Yes, zoom did tell us all! i think he works for mazda :glare:

When I picked mine up yesterday, we checked to make sure it had all the flashes. The guys at the service dept told me that they had just recieved word earlier that morning to halt the flashes.

no i dont but if they are reading today- i wouldnt mind. especially if they would just like to pay me for the services i provide to other forum members:)

thinking about this furthur i like my original reasoning better. that is- the H files are like version 1.x for 2004 cars and the Z are 2.x . that would make the K files ver 1.x for 2005 cars. sinc they are just now looking at the pcms it seems to follow that they didnt know of any potential differences when the flash files and their numbering were created.

So, is this a new, new flash or is it an old new flash? I’ll try to hold my tongue on the dozen’s versions of “M” flashes but it is hard. I had mine done the first of December or so, got a CEL for a converter code and subsequently a new cat. I haven’t really driven the car since then because of the snow. :(

Any more information on which version of M is bad would be appreciated.

You would think with all the crap about busted M & 1/2 flashes they would be working the N flash..

Heck Mazda should be giving something to all board members for provide such valuable marketing feedback to their product. Not to mention all the technical insight on FI that I'm sure the R&D engineer will find enlightening.

here's one of my recent explanations of the flashes

no, im saying it. and so do our tsb's. the US flash files were previously named sw- N3H4(6)Ex. with the letter after the E being flash level. they were that way up to the first up to the first update of MSP04. then the files changed in the 2nd update of MSP04. to be sw-N3Z1(2)Ex with the letter after the E still being the level. the last H file was EM. the next flash file was the first Zfile which was EL but that was the buggy one that caused them to put out the first stop flashing order. that was replaced by ZEM. but these appeared to all be the same "level" as the updated MSP said if you had HM then you didnt need the Z files.

now a recent TSB(which has now been recinded due to programming concerns) showed new file names for 2005 cars-

sw-N3K6(7)EB for all fed and canada cars and
sw-N3K8(9)EB for all California cars.



if you got a flash in december you more than likely have a buggy flash. the only "good" M is the original HM as far as i can tell since they have halted all flashing now. im suprised you got a new cat since the cat code was a symptom of the bad software. did you get a look at the old cat?

You would think with all the crap about busted M & 1/2 flashes they would be working the N flash..


they are most certainly working on correcting these issues. try to remember that the issue really is that the pcm throws false codes. having a cel lit is annoying but it will be rectified.

I wonder what flash they use when they roll a new RX-8 off the lot. Do they have one that works? Did they stop making new cars or do they sell them with engine lights on?

We should call them Microsoft I guess. Each time you get in your car preform an RX-8 update. Select all critical updates. Your car will need to be re-booted for the updaet to take effect. . . .

You know all this complaining, and I'm just happy that Mazda is doing SOMETHING to address the issue. They keep working on new flashes which in my book is a great thing. They don't have to do any updates, but they do it for us. I'm glad. I just wish the dealers were on the ball with this. I'm happy they keep fine tuning the car. They coulda just left us in the cold if they wanted to.

hahah Zoom44 may know more about the current flash sitiuation since I've tried to keep away best I can from these threads, but comon I would be a way better poster child for mazda. I could top the "zoom-zoom" kid in for love to hate value.

Beside "when you look this good, you don't have to know anything" :p

It's a double-edged sword. The GREAT part is that they can make fixes just by twiddling bytes. Witness how they fixed the flooding issue. A generation ago it may have taken significant hardware to fix it, or they may have just given up. The BAD part is that complexity tends to grow to fill the capacity of the system. Sounds like a real pain in the ass for the dealers to keep up with their versions and naming schemes and updates so that they actually can get the right version into the car.

Mazda DOES have to do all of these updates. they bring a car to the US that doesn't meet the emissions requirements. Yes, they have to flash to make it sellable. Cars flood, misfire, and other misc problems whic means the owners bring them to the dealer under warranty. If they don't want to lose their shirts on 100,000 lemon law cars, they HAVE to reflash to fix the problems. Only trouble is, their re-flashes are buggy, too. Now they have more cars coming back for glitches than before becuase they reflashed them all. I can't believe you think they are doing this out of the kindness of their hearts.

Anybody else find it absolutely retarded that a car this nice makes it to the market with this many computer problems????? I love my 8, but why can't they just make it work??? I have NEVER heard of any other car having this many "updates" to the software. Most cars you just buy them, drive them, and take them in only when something fails. I truly feel like I'm driving the windows 98 version of the automobile.

I got the next flash after "M" right after it came out (after running "M" for months with no problems) and have not yet had any issues with the new flash... knock on wood... :eek:

... I truly feel like I'm driving the windows 98 version of the automobile.
I'd be ecstatic to get Win98. From the sound of the on-again-off-again flashes, this is more like Windows 3.1.

I've got a question. I've only had my car for a little over two months but since I have the cold start problem I have gotten 3 flashes done on my car. Right after the first one which was done Nov 3rd, I started getting CEL's randomly when I drive the car over 7500rpm (They flash for 10-15 seconds and go away). The CEL has only stayed on once and hard coded into the computer as a PO302 which they said was a misfire at over 7500 rpm. Because this happened on a Saturday all they did was reset the light and send me on my way.

The dealership just made it sound like it was no big deal and told me I shouldn't be reving the car that high. This I am not buying, but I didn't argure the point at the time because I thought the CEL's were coming for buggy flashes. I haven't seen any mention about misfiring and flashes combined, until this post. Is that a result of the bad flash or do I have another problem I should be concerned about too?

Dammitanyway! I took my car into the dealer for a problem with high start RPM when very cold, (see http://www.rx8club.com/showthread.php?t=48056 ) and just got it back today. And what did they do to fix the problem? Re-flash the PCM!

Of course, I have no way of verifying the program level as it wasn't written on the receipt. I won't be able to know if it will take care of the problem until it becomes very cold here again. (and I wouldn't mind if it didn't become very cold here again this winter!) The car didn't run any differently on the way home, and I hope I don't start getting CELs, since I haven't had one yet.

Oh how I dream of that archaic Nikki four-barrel carb...

I bought my car.....I had the dealership update the any outstanding TSB's = "M" flash.

I drive the car...I do not flood...I do not throw CEL's...I get 17-23 mpg...my car 'freakin flies after 5000 rpm's without hesitation...I don't stall, sputter, puke, lurch, rumble, mumble, vibrate, or rattle (except for the stupid r.v. mirror which is on order for replacement).

I'm not saying people don't have problems...I'm just saying that not all is bad :)

As of now Mazda wants to get all the cars with P0126 codes back to the original "M" flash. The dealer has two choices.

1) Re-ghost the WDS back to 34.0 (pre M-L-M) and reset the PCM in the car back as well.
This solution does not set well with most dealers because it takes many hours of WDS
downtime to go backwards...Remember...there are other vehicles (6,3 etc) with valid
files you will lose.

2) Send the PCM to the National Tech center to have them take the level back to the flash.


They will fix this issue. The CEL the faulty flash sets is a P0126.

Flame away...I can take it.

so they send it back to the original M flash. that would be great. They told me they will have my car for a couple of days while they have to send it back in to get redone.
Why are they even messing with it if the M flash was working?????? If it ain't broke....

And, I'm sure I'll get flamed for this, but how hard is it to get the car's computer to function consistently and predictably? Is this an impossible task?? Why didn't Mazda have this done months before they ever shipped a car over here?

I tried calling today, but they must be closed this week or something. probably working on that plant rebuild right now.

There is no way to flash the car back to a pervious "older" version using the standard machine they use at the dealers. Unless, they are doing something special its not possible.

Zoom44 confirm? I know this because I've seen them use the tool on my car it simply, "searching for update" checks the version number and if the flash currently on the car is newer then it says "update not found". They can't select from a list a set certain flash which kinda sux.

Polak,
yes the dealer can un-flash a flash. Read Snap-On's post, he is correct. The dealer must clear the hard-disk on a WDS and re-load it with an older version CD. I takes a couple of hours, but if the dealer wants happy customers then it should be of little inconvenience to them. I cannot comment on the sending the PCM in to a technical center procedure, since I am in Europe and not familiar with US procedures.

Tbone,
I don't condone Mazda for repeatedly inconveniencing customers with software updates, and to top it off updates that are supposed to solve problems but actually cause new ones! You have a right to complain, I would.

But just to try and make you feel better, when I worked for Chrysler it took 6 to 7 months, sometimes a year to get a software update to overseas markets! Mazda Japan has to go through the EPA and all other sorts of red tape first, so I think their reaction time is pretty good, if not a little misguided sometimes :o

Also, think about Windows. How many times have you downloaded a Security Update, and something else stops functioning!! That is the reason I got a Mac! I am not saying it is OK for Mazda to do the same, but there are so many programs running at the same time in a PCM, sometimes when you tweak one it affects another in a way you didn't (or couldn't) anticipate. There could also be a hardware issue there too, I don't know.

I do believe though, that if you stick with Mazda, they will look after you in the long run. Mazda customers are very, very loyal, because the company really values each and every one of them. I hope everything works out, soon!!

I cannot comment on the sending the PCM in to a technical center procedure, since I am in Europe and not familiar with US procedures... According to my dealer the "un-flash" procedure is not possible because they are "required" to return each previous CD to Mazda whenever they receive a software update. Can't say whether this is BS, or not. However, I was given the same story by two different dealers.

In my case, I had encountered no problems. I had purchased the car during the November 2004 "hiatus" in providing the M Flash. Being somewhat familiar with software update procedures (and wanting the car to to be "up to date" when I took delivery of it), I simply asked that my PCM be updated to fhe last "non-buggy" version of the "M Flash" and was told that it was impossible.

In my case, a couple of weeks after purchasing the car I took it in for the re-flash that now appears to have been "buggy" as well.

Frankly, I am less frustrated by the on-again-off-again M Flash issue than the complete absence of communication from my dealer with regard to what is going on. I would have expected my dealer to contact me once the version of the software I was running had been withdrawn with a heads up. Instead, I have to rely on discussions on this board to even be aware that there is an issue.

Oh no the new flash turned the 8 into scooby-doos' mystery machine! :D

I have every CD ever sent for the WDS in the past 4 yrs so I have to raise the BS flag on that.

:rolleyes:

:rolleyes:Thanks for the info. I was suspicious of the claim. Another benefit of this forum.

polak - as stated above it can be done but you have to wipe the wds and then reload up to the level you want to stop at. but this affects what they can do for other MZ cars which may have "good" updates at higher wds levels that need to be done.

If downgrading is difficult, why not just re-release the code of the original M flash as a new release. Call it "N", and move forward?

To quote Jean-luc Picard, "There are plenty of letters left in the alphabet".

Or. . . if everything is right in the current M but the CEL comes on once and a while the software could just ignore it since that is what we are supposed to do. That way it would be ignoring only the faulty code where as we might be ignoring a real problem.

it doesnt work like that. each new release contains the previous plus the new. kinda like overwriting when saving a game. in order to go back you have to start over and work your way back up.

Ok guys...I am so very confused about the new flashes. I took my car into the dealer yesterday because the CEL was on for the fourth time in two weeks...but this time it had stayed on for a full week without going off. The car had been idling rough, starting hard (almost flooded it so I finally took it in...and I do not EVER shut it off cold), and completely lost power on a cold, not freezing, day in second gear at 4000 rpms. The dealer told me the code for the CEL said something about the gas fumes not being released? (ok, really I have no clue and think it was a bunch of BS...code was P0456). Well anyway, their solution was of course to reflash with the newest flash (after I talked to the service tech and asked him to make absolutely sure that it was not the flash that had been halted). It says that they reflashed per bulletin 01-024/03. Now...with that information, did I get the screwy reflash that they weren't supposed to use yet? I really don't want to have to take the car back in for service again in the next week or so. Just for the record though, car ran great on the drive home from the dealership...smooth idle, easy starts, no loss of power, etc.

Tbone: I couldn't have said it better myself! Two more times into the shop for a no start and I'll be talking to a lawyer about the lemon law. I love the car also, but I can't live with these neverending problems.

(ok, really I have no clue and think it was a bunch of BS...code was P0456). Well anyway, their solution was of course to reflash with the newest flash (after I talked to the service tech and asked him to make absolutely sure that it was not the flash that had been halted).

P0456....small evap system leak. Emission system issue. Different code to the one causing the problems. Could be a loose hose clip, could also be the PCM or flash. Whatever, it's a different fault. Not a major issue, though.

As Gomez stated the code the PCM stored was for a EVAP system code..

NO EVAP CODES will cause a drivability issue. The system is different than most cars as it will test after the car is shut off. It works like this..

http://forum.mazda6tech.com/viewtopic.php?t=16&highlight=pbe

The latest flash will flag a P0126 code on HP cars..

Looks like they took you back to the "K" flash based on the 01-024/03 TSB flash file nomenclature. I suppose that the original [read good] "M" flash would have been preferrable, but at least it isn't the faulty "M" flash. Be thankful that they did what they did, because it is apparently quite a hassle for them to set up their WDS to do that.

If and when Mazda gets the newer flash, whatever they call it, straightened out, it probably would be a good idea to have it re-flashed. That is, after lurking here for awhile to make sure it isn't another bad flash.:(

Looks like they took you back to the "K" flash based on the 01-024/03 TSB flash file nomenclature. .:(


no they didn't. they used that TSB to justify flashing the due to the code they found. the TSB will say "if problem Z found flash to at least level x or newer with a WDS at level x or higher. so they gave her whatever the lastest flash they had in their WDS.

2 problems from my view-
a.she was already at a higher level than what was required to stop the false evap test failure codes. so they should have checked for furthur reasons for the test failure code.

b. she specifically asked them to make sure that the flash they were going to use was not a problem. if they had called the tech line to verify- LIKE THE CUSTOMER REQUESTED- they would have been told NOT to do the flash.

my conclusion- whatever caused the code could very well still be an issue AND she could very well have buggy code:(

with all this talk about "flash" this and "flash" that, I'm starting to hear queen in my head..."Flash....ah ahhhhhh.....he saved every one of us!"..........."Flash...!....." :D

"WHAT do you mean flash gordon approaching? open FIRE! all weapons. dispatch war rocket agents to bring back his BODY!" ahhh Flash....":D

I have just ONE question - what do you do if you got the latest flash that may still be buggy. Do you take your car in so they can send you ECU off or do you have to wait for a CEL? :mad:

The "buggy" flash may or may not set a CEL on your car.

A quick recall from some PM's (along with other input) tells me this effects a small percentage of HP cars. I have yet to see a auto tranny car set the CEL for the P0126

I took my car in for a 3K oil change. I explained to him that I knew there was a halt on the latest Flash, but the service guy assured me there was no halt on "this" flash and gave me the latest flash. I wasnt having any problems with my 8. I hope I didnt get the troubled flash that was in a thread from last week. The service reciept says:

"Mazda Special Service Program MSP04. When vehicle fails to start, Hard to start, Lack of Power, MIL with DTC P2107/2108,P2404,P0420. Applicable models VIN built prior to March 12, 2004, VIN RANGE:40100004-40135536, Install the needed calibration, check by starting the engine and no lights are present, 99/99, A4432H,N3H418881A AT, N3H6 MT, XX682XRX,3"

the part numbers you posted are for the original M flash which was fine. however i cant tell from what you posted if that is what he gave you or if that is just what printed since they printed the info about MSP04. he could have "ghosted" his wds back to that level but i would be suprised to hear that he did. did they list any part numbers seperatly from that line. also what is your cars build date? also did you have your car flashed previously?

the part number on the reciept says 26MAZMSP04. I dont know the car build date. I think its on the sticker in my glove box. I will have to look. This is the first flash I have had since I picked my car up the day after Thanksgiving.

The flash error was corrected on the 34.6 update as I recall..the dealer should have 34.8 as of last week. Maybe they are not updating the WDS as they should.

If you had a P0455/456 code for a fuel cap it will be the first I've heard of.

If they can't duplicate an issue with your car maybe they're not driving it the way you do. Take someone from the dealership for a ride and show them. Here is exactly what they wrote up on the repair order about the Code;

9330 F0008XDX F0502XRX 0.7 PO456 EVAP LEAK VERY SMALL LEAK RAN EVAP TEST FAILED PERFORMED SMOKE TEST AND THE SYSTEM PASSED. TESTED THE FILLER CAP IT WAS LEAKING REPLACED CAP

What else would the PO456 be caused by?

I have to take it back first thing in the morning so they can have one more crack at fixing the gas mileage issue.

Ok I just got back from my appointment with Mazda. I had requested a meeting with the DCSM, all I got was the service manager. They checked the PCM and found a new flash.

I already had the "M" flash as per MSP04 when they flashed it back in May.

Now don't get excited, they called it 34.9 which we all know is the WDS revision level. When I pressured them about the file name that they downloaded to the PCM all they could tell me was that it is the latest for the manual tranny and again told me it was 34.9.

So what flash revision later them MSP04 is in the WDS 34.9?

Just driving home, I could feel a big difference in the engine response. Not necessarily more hp, but I only had to give it half throttle to get the same accelleration I got before at almost WOT. That could translate into better mileage, but I'll wait to see some numbers I can average over the next few tank fulls.:D

I am still curious about the flash level in 34.9 that is later than the "M" I had previously.

My totally unqualified, unfounded and unreliable opinion is this (I have to say that as an 'official' disclaimer):

If you have driveability problems and/or unexplained MIL illumination after having your vehicle PCM flashed to the latest level, ask your dealer to return it to the last 'reliable' flash level. How this can be achieved is going to be between you, the dealer, and MNAO, but it is a reasonable request. Those of you who have tried this to no avail, try again (but harder!).

Good luck.

For what its worth, the dealer just flashed my car to the latest, under the MSP04 bulletin or whatever...and I'm pretty sure I was at the M flash already. However, so far no CEL or anything else, and power is either the same or better (my butt dyno says I'm getting better power up top but I consider it very suspect).

jds

Just got flashed yesterday (was already M due to rough idle and extremely rich). Told service tech not to reflash but he said they got another version and it was fixed (I never believe what they tell me). Haven't had a CEL yet but I did notice a bit of lag in the upper range but I haven't given it any more runs up top to see if she was just being finicky.

Try driving hard in 3rd gear and shift into 4th just as hard. I am getting a CEL when I do that. Never got it before.

I'll give that a try tonight or tomorrow morning and let you know (via this thread of course).

Yeah.. I am running way rich now too. Popping on almost every gear shift above 5,000. I have a CANScan unit and was logging 11's throughout the rev range.. yikes.

Yeah.. I am running way rich now too. Popping on almost every gear shift above 5,000. I hae a CANScan unit and was logging 11's throughout the rev range.. yikes.

Does the CANScan read the CEL?

Yup. P0003, which I still have yet to hear what that means, and a P0100 (MAF Sensor Related).

Last night I took mine hard (to 9k) through 1,2,3, and hard into 4 three times in a row. I did not notice the slight lag I thought I felt on the way back from the dealer (above 7,000 rpm) nor did I get a CEL. I'm guessing mine might be OK and for once my service rep wasn't BSing me.

I'll try that test on mine as well. So far so good, but I haven't specifically done that.

How do I know IF I have the M FLASH? Is there a way I can check? Please email me with any answers...... joeoh89@yahoo.com

If and when Mazda gets the newer flash, whatever they call it, straightened out, it probably would be a good idea to have it re-flashed. That is, after lurking here for awhile to make sure it isn't another bad flash.:(
Just got my car reflashed yesterday morning because of poor gas mileage (9-10mpg). They could not tell me what flash level I got, but said the WDS version was 34.9. and I had the original "M" back in May.

Anyone know what flash is on 34.9?

BTW, 2 weeks earlier I had a CEL with code PO456 and they replaced the gas cap.

Either way, I don't have any mileage numbers yet, but I do know that I got 50 miles on the first 1/4 tank whereas before I would only get 69 miles out of a 1/2 tank. I guess that means that it is better unless the next 19 miles take it down to 1/2.:rolleyes:

maybe the flash just changed the way the needle moves....

I only have two numbers on my car. Guess I cant get the file name that they used.

N3H6-18881-M

SW-N3H60M000 I think..

If we ask, can they tell us the file name they used to make the update?

\

So what flash revision later them MSP04 is in the WDS 34.9?

I am still curious about the flash level in 34.9 that is later than the "M" I had previously.


have you read my posts about the changing of the file names? hopefully you have so you understand what i say next- the newest wds level is now 34.10- remember that is used ford parent company wide so not every new wds update has anything to do with a mazda product or the rx8 specifically. so the wds level that had the msp04 flash had the file named N3HxEM or M flash. after that files are N3ZxEx. Z-EL was the known buggy flash and Z-EM is the supposedly unbugged flash. 34.10 still has the Z-EM and nothing newer. so that means 34.9 also had the Z-EM file and nothing newer.

Anyone know what flash is on 34.9?


i gave a long answer in the other thread
short answer Z-EM or the supposedly unbugged file

So it's a matter of the WDS level? is 34.9 related to WDS? I thought that was just the diagnostic tool..

No flaming please :)

Be kind haha....

***Just saw your other post....*** Looks like it's related...

I only have two numbers on my car. Guess I cant get the file name that they used.

N3H6-18881-M

SW-N3H60M000 I think..

the first is the part number for a flash with the last digit being the level

second is the actual file name except after H6 it should be an E. letter after the E is flash level. that number is for the original Mflash. new part number and file names have replaced the H with a Z and the number after the H for auto/manual has changed.

So are we to trust the file name on the sticker or can they verify it somehow using the WDS..

I dont know how you keep all this straight..

Thankx for relaying all this good information to us.

its either a gift or a curse....

i would tend to believe the sticker since they had to take the time to do it. if you have had nothign since then you are on the original H-EM flash. i wouldnt worry about getting anything newer until you had a problem described in a future TSB. im not.

I have read what you said about the file names and thank you for that explaqnation. That means that I had "M" from back in May and they just reflashed with Z-EM yesterday from WDS 34.9 which they thought was the latest WDS, in an effort to cure my mileage woes.

That was the reason they did the "M" flash back in May, to fix my mileage. Funny thing is I was getting 13-14mpg before the "M" flash and after it went up to 17-19 during learning mode. Then over the course of 4 months it dropped down to 10-12. Then after another 3 months it dropped as low as 9-10. Now I get the Z-EM flash and mileage and overall performance seem to be better right off the bat on the first 1/4 tank I have used. Part throttle response is definitly better.

So what will happen now over the next 3 months? Why does it appear that it runs better when it is in learning mode right after a reflash or battery disconnect as it did when they reset my P0456 CEL?

I will definitly keep a close eye on the mileage again.

I am getting a P0100 but it's not listed on the TSB.. Maybe I should try getting the new flash... Thankx for the info.

maybe the flash just changed the way the needle moves....
The pesimist in me wants to agree but the optimist in me wants to say who cares as long as it will pass a gas station.:rolleyes:

i gave a long answer in the other thread
short answer Z-EM or the supposedly unbugged file Thank you I got both. Did you see my question about mileage being higher when the car in is mearning mode in the other thread? That is something I am concerned about since it would actually point to something else being the root cause for my poor mileage. Maybe the current on the MAF or O2 sensor is different during learn mode on my car and one or both the sensors or the ECU or wiring harness needs R&R.

Is there any way to determine how long learn mode is actually in operation?

I also read somewhere that not all MAF sensors used in the 8 are accurate or may just barely be within operational specs. Is there a way the MAF can be checked independently of the ECU?

Well I got my car back on Jan 4. The dealer service order says "Incorrect PCM Software. Remove PCM Send to Mazda for Reprograming, Reingstall 6X 9J (PCM PNMC)"

Yesterday, the car seemed OK, no check engine lights or anything...but then again the last flash took a couple of days before problems showed up. Then today I start the car tonight (ambient temp 20F) and it starts quick revs up to about 2200 RPM sits there for 30 sec and then drops down to 1000RPM. After about a minute of idling, the RPM drops down to about 750RPM. The whole car starts shaking, the steering wheel starts vibrating violently, and after about 10 seconds of this, I think I need to get the revs back up a bit. I barely tap the throttle and the car just stalls. When I start the car back up it starts up instantly revs to about 2000, drops to 1000 and is fine.

This is about the same problem I was having the right after I got the car flashed originally a couple weeks ago, but before it the engine would stutter, then stall under a light load. This time I was just waiting for the car to warm up, so it was sitting in neutral.

I guess it is time for another call to the dealer.

let it learn a little before you jump on them. it could be the new ecu needs a couple of start cycles to really settle in. see if it clears up over the next day or 2

Thanks for the advice, I will give it a bit of time, and see what happens over the weekend. I just filled up the gas (after this occured), so if it was "bad gas", it shouldn't happen again.

had cel problem in december. dealer replaced pcm and reflashed, not sure which version. one week later no start! dealer relaced all spark plugs with updated parts. Anybody else need a new computer or plugs yet? only have 6700 miles on my titanium 04 6sp.

does it cost money to get ecu upgrades? no right,...

they did not want to do the m flash because they was scared if it messed up the E manage. That what they said.the dealer

I did read through this thread, but didn't really find the answers to my elementary questions....

I know the ECU is the computer that controls fuel input and the engine to some extent. I know a "flash" is an update to the firmware code in that computer. How does that relate to my 8??

How do I find out what version of ECU software my car has (do you need to go to the dealer?) , and is there any reason to request a flash to the newest one, other than the fuel consumption issues described here? I just got a used '04 and have no idea what it 'started' with. How does this alter performance or anything else?

you should be at least on M flash. if your car is on an earlier flash it needs to be updated. aske them to check your car for available updates. Mazda wants all 2004 cars brought to at least M so if yours is not they shouldnt give you any problem over it. there is no tsb for the P flash so it doesnt addres any particular concerns THAT WE KNOW ABOUT RIGHT NOW.

Dear everybody,

Does anyone know what really does the R Flash over the N Flash?

I have read through different posts that mileage seems to be better and that there is a bit of low/mid revs torque, but still not numeric/objective data (i.e AFR vs speed and load, ignition timming...) about that.

I am currently on N (from M) and I am enyoing the advantages of N, but would like to know how worth is to go to R.

Regards

jird20

we dont know what change from N to P so not going to be much help there. we do know what changed in R. read the recall papers:)

I havent gotten mine yet.. Can you point me somewhere that I can read this if it's posted online?

check the rosenthal tsb page;)

does it cost money to get ecu upgrades? no right,...
Generally, No. You should not have to pay for them to flash your ECU to the latest version if they are told to by Mazda. But no all dealers are created equally and there is the odd chance that one might try to charge you if the latest flash isn't part of some upgrade program they have to do. Watch this forum and learn about what you want and what you don't in terms of flashes. Not every 'new' flash has provided significant changes or noticable improvements.

As for low RPMs, I have noticed that Ignition Advance keeps at 44 (highest) above 3000 RPMs. Anything lower than that goes down to 43 and below. Anything higher than 4000 RPMs, it's all kinds of ranges. Above 6000 RPMs, open-loop, 30 is the maximum.

I have just gotten 275 miles and the fuel needle is at the 3/4 line (1/4 fuel is left). This is with a 90%HW/10%City, REVi intake + Ram Air, and hot plugs.

Pretty neat :D

Thank you Xyntax,

As far as as I have seen, R Flash is pretty new (July) so about exceptions like yours, there is no much experience about it in general.

I will keep on following the threads about this interesting topic.

Cheers

Okay guys, I'm new to the forum and I'm just researching things for my mom's RX-8, so please don't be harsh on this poor 350z owner :)

Her build date is 10/04 and the car gets terrible gas milage. She doesn't really need any more power because she won't really notice the difference. The main thing is the gas milage.

I've read a little bit about the flashes, but I still don't know what to ask my dealer. Can someone clarify this for me?

what do you mean by poor gas mileage?

I can watch the guage go down as I drive basically. I haven't had the chance to test it over more than 100 miles, so I haven't been able to record it. My mom is automobile stupid, so she doesn't know what kind of milage it's getting. I'm guessing about 225-250 a tank, all interstate.

It's a 6-speed by the way.

anybody can watch the guage go down as you drive for 100 miles. when you have actuall numbers come back and ask again in a MPG thread. there are tons of them. but x miles per tank is not useful information at all. not worth getting into and hijacking this thread anymore. get miles driven and gallons for refill. gear,cruise etc etc.

Thanks for the... uhh .... help. I guess.

Thanks for the... uhh .... help. I guess.

You should read the sticky in the issues and problems section by Polak about several flashes.

Until you establish your true mpg not miles per tank, we won't know if your mpg is low or not. miles per tank is useless.

The site has many :eek: mpg threads ... it is one of our favorite :rolleyes: topics ... it's a sports car.... do a search

as with many engines the rotary mpg improves with miles....

Thanks for the... uhh .... help. I guess.

The fuel tank meter is not linear, the first half tank goes really fast, but the third quarter usually last forever:

60 miles when needle is at 3/4 (~60 miles for fist quarter).
130 miles when needle is at 1/2 tank (~70 miles for second quarter).
230 miles when needle is at 1/4 tank (~100 miles for third quarter).
270 miles when refuel-light turns on, this is 1/8 before empty on the scale.

So, the first half gives the impression the RX-8 is a guzzler, but the last half gives the impression the RX-8 is very fuel efficient. My RX-8 manual oscilates from 19.5 to 21 mpg, that is with a lot of bumper to bumper and city driving here in LA.

Newer flashes usually show better mpg. Besides, this rotary engine get much better mpg and jump-off-the-line-acceleration as it breaks in, looks like that is after the 5000 miles.

I have had every flash, and from day one my ecu is clear of errors and I get 140 miles per fill up - thats about 12.8 mpg. These flashes do not help enough to change my gas usage. Even when I baby it I get 13.1 mpg. There is somthing else going on. I do mostly city driving. On the highway I get 18 mpg.

So I had the recall work done today and when I ask about the flash version I was told...N3Z1-18-881S. I understand now that the 'S' version is for AT, my 8 is a MT. Car runs fine, redlines without issue...and seems to do so smoother then before the recall. Idle is about 100rpm higher, smooth idle. I would think that if I had the AT flash I couldn't redline to 9K...comments?

I have noticed that the AC doesn't work as well...not sure there is any relationship to the recall work however. As for the recall itself...no issues found.

i got mine reflashed today as well - to N3Z1S .... which "version" would this be considered? R?

ok I hate to ask this question as I am sure it has been asked before. but I couldent find anything on a search. so I decided rather then start a NEW thread, I would just revive an onld one. :)

what does the new flash (on the new recall) do? (I hear it injects more oil, and thats about all I have heard. I am sure it does more then just that.)

and what "letter" flash is it? (N???)
only info I found was this would be my flash N3Z2-18-881T (2004 M/T)

I found alot of info on the thread that talkes about the J,K,L,M, flashes, but nothing recent.

thanks to who ever has the answer.

All I know is my flash code was 5 digit's long and ended with a 'T' which is the latest reflash for an '04 MT they said. The '04 AT cars get a 'U' at the end of theirs I believe.

Who knows what the heck these things do anymore. Car seems to be doing well with it so I would make the appt. and get'r done. They also check the cat, and a few other things per Mazda's direction.

Go the the link below and see the table on p.16. The letter doesn't much matter--although I suppose it's "T"--as long as the part number of the update is the correct one for your vehicle and location (which it is in your case.)

PoLak,
In this helpful sticky that you made, would it be too troublesome for you to edit in approximate dates when the said ECU flashes were introduced?

http://www.rx8club.com/showthread.php?t=50119

I just got a used '05 and I'm looking into getting a new flash. I looked through this thread and a few others about the flashes, but I didn't really find the info I want. Is there a significant flash for the 2005s, or just the '04s? Also, what other stuff should I be looking for in terms of dealer maintenance or recalls? They never fixed the foamy oil problem, so I'm thinking of getting that done too.. Having to check the oil 27 times before you get an accurate reading is ridiculous.

But yeah, Flash it or no? I don't know what version I'm on, but i tried pumping the brakes 20 times and nothing happened. Is that only for 04's?

just go to mazda usa and sign under owners with your vin. itll tell you if you have any warranty or recall work that needs done. or just call. if all recall work has been done you're on the latest flash

How are you guys getting this mileage of 270?

My light comes on at 180 miles.

It says there are no recalls.. But it also doesn't say any repair info either, so that must be wrong? Shouldn't it have a record of the repairs the previous owner did?

Anyway, I called my local Mazda Dealer (Schwartz Mazda in Shrewsbury) and they said the car had some work done before.. 2 sets of plugs, replacement cat, upgraded software and replaced the rotors twice because of rust. They told me if I wanted the newest software I'd have to pay for 1 hour's labor.. :( that sucks. I'm going to get the milky dipstick recall/tsb done because I can't check the oil ever, so maybe if I ask nicely they'll do upgrade the software.. If they make me pay for it, is it worth it?

ask what letter the flash is. my dealer told me there hasnt been anything new since the 06 recall.

recalls are done you are golden as far as flash is concerned. the owners bit lets you keep track of what YOU do and tells you if there are recalls that need to be done. It wont tell you what the previous owner did- even if he bothered to keep track on there

So what is the latest flash? There is a sticky thread that Polak started but nobody seems to update it anymore.

t or something. look at the recall pdf they are different depending on model year etc

Apparently there is a new flash out?
I had a CEL. I have a 2007 6MT. The build date is Dec 2006. I took it into the dealer to clear the CEL and they said there was a new update PCM and they updated that. So either it's new, or there was a PCM flash update between now and DEC of last year?

Anyone know anything?

no idea - when last i checked about a month ago there wasnt anything new. im currently unable to check. got any supporting paperwork from the service that might have the number?

yes as I do.. I asked them to give me a copy of the computer report. Here is the pertinent info>

PCM Part Number: N3M5K
PCM_FILENAME: SW-N3M5EK000
RCM Part Number: _14B056_DA

I don't know what this filename means. I've only heard of people on this forum talk about stuff like "M revision, N revision etc.. etc..."

Please help Zoom44!

well there ya go- your 2006/07 us fed/ Canadian emissions 6mt rx-8( thats the n3m5 part) is now on the "k" flash(the letter after the e) for that model year car. that means thre have been 4 flash revisions(not 5 as they skip i so as not to confuse it with a number) since the recall flash posted by me again a couple posts ago. flashes are usually just minor bug fixes. so since there hasnt been a big tsb or recall for awhile thats more than likely all they are

So is "K" the latest flash or what? It's confusing since I read about M, N, R flash etc...

This is confusing, the flash letters in Canada are not the same as the flash letters in the US.

yes its confusing:) there are different "part numbers" based on different Model years now. in the beginning there was mnr etc but with different model years they had to separate the flashes because of changes in regulations and because of a physical change to the pcm . canada bulletins may list a different number but the underlying flash numbers are as i stated above

2004 A/T (All) N3Z1-18-881U SW-N3Z1EU000
2004 M/T (All) N3Z2-18-881T SW-N3Z2ET000

2006 M/T (Cal) N3M1-18-881F SW-N3M1EF000

where the letters/numbers before the "e" are for the model year/transmission/ emissions spec and the letter after the "e" are for the flash level.

2004 & 2005 AT flashes are one letter further on than their comparative MT level. When we talk about M N R etc we are talking about 2004 MY levels. 2005 2006 and 2007 codes started later than the 2004 year so they are at a different point in the alphabetical nomenclature. The newest flash level for your vehicle is "K". as far as i can tell for now the 2006s and 2007s are on the same flash part starting with N3M1/2/5/6 .

whenever it says"fed" that means the US FEDERAL EMISSIONS SPEC and includes the Canadian emissions spec. Cali means California and other states that have picked up the California emissions spec.

damn!! im already confused and i just read the first and last page....someone lace me up on the info....on whats the newest and latest flash??? do i have to pay for it if i have warranty??? how can i tell if my car has already been flashed???

so for example if i have an 06 rx-8 i should have 2006 M/T (Fed) N3M5-18-881F SW-N3M5EF000 which would meen it comes stock with f? and f = some base map? the old ones were l but what would the newer ones be on? you say the newest is k, did they go from m, n and wrap all the way around between posts?

hi all. i need some help regarding reflash and ecu updates. i picked up my '07 gt model in oct '07. my dealership closed down and i just scheduled with star mazda in glendale CA. they ran my vin and said there was a recall for my '07 car regarding an ecu update.

my question is... what is my current flash for the '07 and are any current updates gonna be better than the older one i have in my car?

the service advisor said the recall was based on customers complaining on low on power... so what do you think they're gonna put in? and how significantly different is the map changes?

thanks in advance
trochoid

^^btw, help would be appreciated.
i did my search, and was linked to this thread to ask my question. schedule appt is for coming monday, tomorrow.

edit: phil...trust me, i tried. and some posts either cannot be shown, and topics regarding this are either 40+pgs or whatnot.
i'm concerned... just not enough time to do the research. trust me...i wouldn't be lazy, and its not like i'm a newbie or something... just need the extra helping hand for a hard to answer topic.

any answer or help is greatly appreciated.

Not sure you know how to search - go to Rosenthal forum and see if you can figure it out from there.

well there ya go- your 2006/07 us fed/ Canadian emissions 6mt rx-8( thats the n3m5 part) is now on the "k" flash(the letter after the e) for that model year car. that means thre have been 4 flash revisions(not 5 as they skip i so as not to confuse it with a number) since the recall flash posted by me again a couple posts ago. flashes are usually just minor bug fixes. so since there hasnt been a big tsb or recall for awhile thats more than likely all they are

zoom: sorry for my curiosity and concern. i've found a new dealer to bring my car in due to the purchasing dealer closing down...
anyway, asked for warranty alignment. but was scheduled for both alignment, AND a ecu recall for refalsh of owners complaining low on power for my '07 GT with 6MT.
i don't know what current flash its in... but would it be fine to go with their new "flash" update? - i have known its been asking me to fuel up sooner... but as mpg goes... i haven't the chance to calculate what its getting now. and it does seem a bit "lagging" around 6k~ above RPMs...

is it gonna fix it? better gas mileage?
what parameters are altered for the new flash? STFT, LTFT...?

ok... so looked up the new updates in the bulletins.
among the list of fixes...it alters MOP settings and ignition timings for high amb temps.
there are actually "2" bulletins out.
01-013-08(lack of power pcm reflash)
01-014-08(lack of power) but is more based on customer complaints and detailed checks(carbon removal,coils, ssv, baro sensor, etc) and failing under this/those checks will warrant an engine replacement
sounds correct so far...right?

ok, so according to the bulletin, if i go in for the recall i will be getting part #
N3M1-18-881k which will be a "K" flash by the part #. is that correct so far?

I checked mine today, i have the "U" flash "sticker on door jamb says 11-26-2007" by Mazda and verifies w/Mazda VIN serial # search at dealer, this flash might explain why engine was so clean. "J" flash done previous year b4 the "U". It Runs Gr8t, it does love oil though 1/3 qt. every fill-up:beer: , if i get on it , but then again this car is so fun to rev, i'm waiting for it to hug me back...

How would I know if I have the latest flash? Do they automaticly check when you bring it in for routine service?

I would ask the dealer to check there computer (Mazda warranty vehicle history report) the service Manager should know how to retrieve this report, i would not rely on them telling you, you must be the punctual one here just like the Dr. giving you a prescription ask all the questions until you understand and feel comfortable, i noticed after looking at my report the dealer ran for me the U flash is not on the report but my local dealer did the Flash and the sticker is on the driver door jamb. I will have discussion with them on Monday morning...:uhh:

i just got myh new V flash done while i had in the shop for other stuff. it doesnt take long at all either and it is worth it.

Visited Mazda dealer (Auffenberg O'Fallon IL) and got the repair history on why it got the "U Flash" apparently the dealer whom the guy traded (original owner) in on a Chrysler product, flooded the car and had to have it towed, gas cleaned out of engine and U flash done, Chryco dealer refused to have battery replaced and starter upgrade. Dumb ass Chrysler dealer :anger: knew the battery was insufficient, i had the dealer i bought it from replace it before i purchased the car. Mazda told me anytime car is in for service it is always in their best intrest and ours to do "ANY" PCM Flash updates. Getting starter upgrade tommorow.

Got new starter installed this morning, it has made a BIG difference, engine does not even t rn a full cycle and it is on, WOW :jump:

04 with 40K miles - manual trans

What is the latest flash? I got mine done in Sept 08. Dealer said it was for 'improved performance'. Well, the performance did not improve (you can't get more torque out of a 1.3L rotary engine, period - and the thing always performed very well >4K rpm) but I lost 1.5 mpg and now I have this weird very high resonance vibration. The engine sounds more like Lauren Bacall than Beonce, if you know what I mean. A bit gravely. After running with this flash for 3K miles the vibration is now at a point to where at the end of my 30 minute morning commute my hands and feet feel like I've been in a low electrical field or something. Very strange buzzing sensation (and no I don't partake of any substance abuse during the commute).

Anyone else experience either the mpg drop or the weird sound/vibration situation?

Thanks

I got mine reflashed in Sept 08. Dealer said it was for 'improved performance'.

Could be a worn motor mount. or something they did other than the flash causing it. I would bring it back. A re-flash should not cause vibration at cruise on the highway.

Hey zoom44,

Thanks for the part numbers you provided.

I visited my dealer yesterday and asked to check my ECU version to make sure there's no update available.

Computer showed that I have the latest version available. I have a 2004 MT and the version is N3Z2-18-881U

You mention that lastest version for 2004MT is N3Z2-18-881T

Does this mean that my dealer didnt have the latest T version available?

yes its confusing:) there are different "part numbers" based on different Model years now. in the beginning there was mnr etc but with different model years they had to separate the flashes because of changes in regulations and because of a physical change to the pcm . canada bulletins may list a different number but the underlying flash numbers are as i stated above

2004 A/T (All) N3Z1-18-881U SW-N3Z1EU000
2004 M/T (All) N3Z2-18-881T SW-N3Z2ET000
2005 A/T (Fed) N3ZA-18-881H SW-N3ZAEH000
2005 M/T (Fed) N3ZB-18-881G SW-N3ZBEG000
2005 A/T (Cal) N3ZC-18-881H SW-N3ZCEH000
2005 M/T (Cal) N3ZD-18-881G SW-N3ZDEG000
2006 A/T (Fed) N3M6-18-881F SW-N3M6EF000
2006 M/T (Fed) N3M5-18-881F SW-N3M5EF000
2006 A/T (Cal) N3M2-18-881F SW-N3M2EF000
2006 M/T (Cal) N3M1-18-881F SW-N3M1EF000

where the letters/numbers before the "e" are for the model year/transmission/ emissions spec and the letter after the "e" are for the flash level.

2004 & 2005 AT flashes are one letter further on than their comparative MT level. When we talk about M N R etc we are talking about 2004 MY levels. 2005 2006 and 2007 codes started later than the 2004 year so they are at a different point in the alphabetical nomenclature. The newest flash level for your vehicle is "K". as far as i can tell for now the 2006s and 2007s are on the same flash part starting with N3M1/2/5/6 .

whenever it says"fed" that means the US FEDERAL EMISSIONS SPEC and includes the Canadian emissions spec. Cali means California and other states that have picked up the California emissions spec.

Another question that intrigues me regarding reseting ECU with the 20brakes pump maneuver.

Whenever I reset my ECU using this technique, the car becomes a BEAST for 1 engine cycle. It becomes SO different : throttle responds so quickly, torque is higher at mid rage, RPM is smooth and constant, the car feels suddenly ligther and specially specially (the part I dont understand) the gearsbox becomes so smooth and shifthing is much much more easier.

I simply need to perform the 20brakes, turn on the car, and already the gearbox feels so smooth, so 'neutral'...

Is there any explanation to that? I just love to drive my car with ECU reset which is somehow ridiculous...

Also, whenever we do a ECU and PCM reflash (odometer + 20brakes), is there any SPECIAL learning driving routine that should be used? I know it was mentionned in one of the TSB to drive the car for 30sec at RPM blablabla...

Is it necessary and important?

I'm sorry if these questions were answered before, simply guide me!:)

Thanks all!

If you check the date of his post, that was a little over a year ago. There was probably a since then.

Thanks all!The PCM will relearn it's expected setting that Mazda were shooting for. These settings are not necessarily for maximum performance. They have to comply with government standard for emissions too.

is there a good/better/particular way of driving to make the PCM relearn the expected settings?

is it normal that my car becomes so much smoother and faster when I reset ECU? What about the relationship with the gearbox? I can tell the difference right away when changing gears even in neutral.

Thanks:)

Could be a worn motor mount. or something they did other than the flash causing it. I would bring it back. A re-flash should not cause vibration at cruise on the highway.

Thanks Shaun

You called it. Broken motor mount. She sings like a pro again.

okqy so if i dont know what flash i currently have on mine, how can i find out? i have an 04 and as to my knowledge its never been messed with as far as the pcm. so should i ask for a new flash? and if so which one?

Only the dealership can tell you which flash you currently have on the PCM. You'd want the most up to date flash mazda has released.

If you have the Nav system, can you find out what flash you have in the secret menus?

I would be interested to hear about these secret menus. Tell me about them please.

Unless this poster knows something of which I am unaware - there ain't no secret menus and the Nav unit has no direct connection to any part of the car other than the placement and electrical power connection to the car.

The easiest way for you to gain the "flash" knowledge is to look under the hood. The dealer placed a tag with the flash information normally to the hood lip. Or stop by your dealer and have him run your Vin.

EDIT: Why worry - by a Cobb AP and then you don't need to worry about which flash you are on.

Well I have not yet tried this but that's what I get for being so sure. I think it's only good for 2009s but hell I was wrong about it being there.

Thank you Spirograph - I will try this tonight just for a kick - never heard of it nor see it before.

I've accessed all 3 menus on my '04. There's all kinds of logged data from way back when it was new, and a whole bunch of stuff that I don't yet understand.

hah wow i had navigation in my car for over a year and i just sold it for a lotek pod, now i kinda wish i wouldve seen this before :icon_no2:

Here in Croatia things are a little behind the US,the latest flash available is N3ZH-18881-C , does that mean its a "C" flash or is there a code difference for European/Jap flashes.

what is a m or l flash

what is a m or l flash

Flashes are similar to BIOS updates to a PC. The 'Flash' updates the RX-8's ECU with newer instructions based on what Mazda deems necessary. The letters correspond to the release of the flash. Its been a few years since the last flash. If your up to date on recalls you also up to date on flashes. A simple call to Mazda USA with your VIN can confirm if there are any open recalls.
