Looking for Cobb AP tunes
 

Hey everyone, I recently got an accessport and have been exploring its tuning capabilities. I have the AccessPort Manager and AccessTUNER race tuning software, but don't know enough about editing these to feel comfortable about creating a new map from scratch, but I am competent enough to make minor updates as I add to the car.

Currently I am running MM's most updated base tune for my car, but that explicitly states that it isn't supposed to be used with a modified intake, and probably isn't set up for an exhaust upgrade either. The tune works great in my car right now, with a much smoother engine feel, powerband, and idle. It might make a bit more power than the stock map, but not enough that I could feel much of a difference.

BUT, I can't edit MM's tune with my software (i'm guessing he locked the file), so I can't improve on his tune to compensate for my modifications. It works fine, but I feel like I am wasting a lot of the money that I put into the car mods, as I haven't tuned to really utilize them.

So I am looking for a tune optimized for an rx8 with minor modifications that I can use as a starting point to do my own tuning.

Mods to my car: Brand new engine (I have put about 2000 miles on it so far, and was gentle with it for a 700 mile break in), RB rev8 catback exhaust, K&N typhoon intake, OMP adapter to run 2-stroke oil, MazdaSpeed lightened flywheel, exedy street disc clutch, plus handling upgrades (MS strut/tien spring combo, AutoExy tower braces in front and back, AutoExe sway bars, Hawk HPS brake pads and performance brake fluid)

Mods in the works that I will try to retune for myself: RB REN v.2 Race Pipe (high flow cat and resonator), RB exhaust header.

If anyone has a tune for an engine setup similar to mine and is willing to share it with me, it would be greatly appreciated! I'm just looking for a good starting point to modify on my own as I add to the car.

Sharing maps is largely pointless on the rx8. If you have the MM service why not get the full tune? I don't understand why you are just running the base tune.

I have a base tune, but only because I still have mods to install (OMP lines, Sohn Adapter, Radiator). When I'm done, however, I will be all over the remote tuning service. Seriously, do yourself a favor and let him do it.

If you're looking for other maps though, I have a valet and no-start map ;)

I was looking for performance maps to maximize the potential of exhaust and intake upgrades. I have one mm tune that I got with the ap, but I am waiting until I can get exhaust headers and cat/midpipe until I consider getting him to tune it. I don't want to pay for a tune now, then again when I upgrade parts

If you got a hold of his base tune, you have his tuning service for 6 months from the time you received it. So no matter what you do, it's up in 6 months.

Again, Your tuning service is up in 6 months! So start now! Even if you do add mods to it, just tell him, and he'll compensate for it. You already paid for it! Use it or lose it!

P.S. For the most part, performance tunes on RX-8's are completely custom. You won't ever find a worthwhile one size fits all solution, because every setup is different, every engine is different, and the condition of all the parts are different for everyone. Yes, it really does make that much of a difference.

I realize that every application requires a personalized tune, but I am sure that there are other rx8 owners out there who have a non MM tune that is a slightly better fit for my car than the map I am currently running. I have the MM tuning service and am making the data logs as I have time. But I can't edit his tunes myself, he locks them. I want to be able to check, edit, and experiment with the maps so I can learn more about tuning.

All I want is a map for a lightly modified car that's even somewhat close to mine, as it is definitely going to be better than the editable maps I have right now. At least to serve as a starting point for me to try creating my own map.

If I can make a good map for my application, I will share it with everyone who wants a starting map like me or for people who just want a slightly improved tune designed for a lightly modified rx8. I don't know how much the diy tuning community here shares, but it seems like a good idea to me.

We get what you are saying, you clearly do not get what Junkman and 9k are saying.

It doesn't work that way.
Each car is unique.
Each car requires a uniquely scaled Maf
Each car requires uniquely dialed in fuel tables

You could probably share ignition maps.

Furthermore the AP is married to the ATR so you can't really load one map from XYZ users car on to your car. You should be able to view the map as long as the ATR version is the same year ... mmmm I think there is a bit of a hack around this.

That's another thing, there are differences in the ECU maps between 2004-2005 and 2006-2008 (might actually be another change in there as well)

Basically what MM is doing is scaling your maf and fine tuning the fuel tables.
You wouldn't believe how rich some of the engines run and so he finds most of the power in tuning the correct AFR.
He might work some magic on the ignition tables and he'll adjust your Throttle duty cycle is you're interested in adjusting the sensitivity of the gas pedal

If you want a good starting point just download or use the Cobb StockStyle or Stage1 map

BTW you should likely ditch the K&N typhoon hot air intake. It does not have a very good reputation. Go with the AEM or back to Stock, maybe the Racing Beat.

You can open any unlocked tune in your ATR program and then if you save it with ATR it can then be installed in your car. The save process converts it to your vehicle.

Just fyi

Thanks Team.

However is there an issue between 04-05 ATR and the 06-08?
Because with my 05 ATR, I do have issues loading other open Maps for 06+

I can't recall at the moment the error.
I'll try and get a screen shot later and post it. Would love it if you could help me fix it.

---- EDIT ----
Ok Team I several maps from other vehicles ranging from 04 to 06.
If I try and load any of those maps using my ATR that was downloaded for my 05 I get this error.

Attachment 225857

So what I've had to do is copy and paste their specific version of ATR (different folder for each) on to my computer. I launch the specific version of ATR I want to use.

Suggestions?

For example if I want to view FazdaRX8's maps (04 IIRC) .. I need to launch a copy of ATR he sent me.

I think that is the error that I get when I try to load MM's tune, I am assuming because it is locked. My problem is that I want a tune like his, but unlocked so I can open and edit them myself

All of MM's tunes are locked, otherwise people would just share them and not purchase his service.

Yes, I realize why he locks his maps, and I don't mind that he protects the work that he does. But MM isn't the only one that knows how to tune these cars, and I bet at least some of the others don't lock their maps. I realize that it won't be a perfect fit, but I don't see how it could be worse than a stock map, and it would give some clues about where to start editing to perfect the tune for my specific application.

TLDR: MM is awesome and I don't mind him locking his maps, which is why I am looking for non-MM maps that are unlocked, and I realize that they won't be perfect.

So why don't you just look at the Cobb Stage1 map?

For some reason the Cobb stage 1 map is horrible for my car. It won't idle, I have to use the throttle to keep it alive. Even after letting it sit and relearn idle it barely does it. Also, above 6k rpm I get a lot of misfires and power totally cuts out. Even the stock map works better than the Cobb stage 1

The only modified item that it appears you currently have installed that will have a large impact on the tune is the K&N Typhoon Intake.

The rest of it doesn't impact the tune or very little.

Load the Cobb Stock Style Map.
Get a few drive cycles in and then get an idle log.
Adjust idle area in Maf.
Drive cycles
Cruise logs in OL
Adjust Cruise area.
Drive cycles
WOT logs in 2nd and 3rd
Adjust fuel tables
Rinse repeat.

Thank you! Do you know where I should look to find information on target values for MAF adjustment, cruise area, and fuel tables?

There are a bunch of threads under my Username that go over all the scaling stuff. I'm too lazy to search for them, but they are on this site.

Cool! I'll check that out

Hi everyone, I just recently purchased a access port, came with everything I need for it to work, the problem is, is that my 8 is an 07 AT and there are no maps on the cobb cd for an AT or as far as I know, so does ANYONE here have or know where to find 04-08 AT-fed maps?!?!?!, apparently I am getting into this at the wrong time cause cobb no longer offers rx8 maps :/, I would use MM calibration service but hes asking an arm and leg just for a custom tune, please please can anyone help

Doesn't look like Cobb ever made maps for the AT

cobb . mazda RX-8 accessport . map listing

They once did, but the Cobb maps are pretty useless.

I read this in a stage 1 map.

YOU MUST USE THE FACTORY INTAKE SYSTEM ONLY. NO OTHER AFTERMARKET
INTAKES ARE CERTIFIED COMPATIBLE WITH THIS CALIBRATION. THE INSTALLATION OF ANY OTHER HARDWARE SUCH AS HEADERS OR CATLESS EXHAUST MAY ALLOW THE VEHICLE TO RUN LEANER THAN DESIRED, WHICH CAN CAUSE ENGINE DAMAGE.

thoughts on the catless?

read that here: http://www.accessecu.com/accessport/...1%20MTv100.pdf

got to there from here: cobb . mazda RX-8 accessport . map listing

Only map Cobb released for the 4AT is the base one that comes with ATR.

Hoping someone can shed some light. I just received my first cobb, and downloaded the online cobb maps in the link above. Whenever I try to load any of the maps, I get this error.

In the cobb that I purchased, there were other custom maps already on the cobb (couple of them have been derived from the cobb maps) and I can't open any of those ones either.

You might get that message if you try to load new maps without loading the Cobb one as a 'base' first with a reflash.

(your mileage may vary, I'm drunk again)

Which Cobb one are you referring to? I tried loading all the Cobb ones available

Is the Cobb installed on the car properly?

I haven't actually put a tune of any sorts on the car as of yet, it's still stock. I was simply trying to read the maps on my laptop, connecting the Cobb to the laptop.

There aren't any specific instructions to get going here...is there a standard procedure to be able to open/edit the tunes?

Typically, accestuner race and an installed accessport should be all you need to view them. Unless you downloaded the wrong year, make, model tunes.

I am having the same problem. I am new to using this tuning system.

I connected the AP to my car and uploaded the stock style tune from my updated AP V2B. During this process it also downloaded the program in the ECU.

Once I did that how do I edit the correct base file in ATR and then upload the tune back to my 2004 MT?

Honestly,
I'm not trying to flame.
But if you can't figure that out you shouldn't be doing this, really, honestly, not trying to be a meanie.

I have a lot of experience tuning LS, LT and other PCM's. Some of these engines had over 600 rwhp and 600 rwtq. The above questions were specifically targeted to understand the file management part and were just basic things that are specific to the way the ATR and AP interface and the rules around which files can be edited. I was having some unusual problems that may not appear frequently. There are some slight differences in the way the map files are managed and the way ATR operates compared to the other PCM and E-PROM systems I have programmed. This is my first import and things are set up a little different.

I did figure out the file management part through trial and error. Most tuning applications have some basic guidance on the interfacing but the instructions I found online did not clearly stipulate how files are managed and what ATR is doing with the data files. Unfortunately, I guess my search skills are not good enough, and I was not able to find out the answer to some of these questions. For all those working on this here is what I learned:

1) The first problem I had was that no matter what *.ptm file I loaded I could not save it through ATR (even the cobb files). I ended up uninstalling and reinstalling ATR and that fixed this problem. It had not been used in a year and something was not working correctly.
2) I started with the Stock Style Cobb Map, edited the parameters and saved the file to my local hard drive on my laptop.
3) The other problem I had was with the AP Manager. Even though I tried to update it and it said I had the latest version, there appears to be a completely new AP Manager compared to the one I was using. So I also uninstalled my old AP Manager and installed the new version.
4) I then uploaded the *.ptm from my hard drive to the AP Manager and then within AP Manager transferred (uploaded) it to the AP.
5) Once it was on my AP I could download the updated map to the PCM. I was able to easily tell it was properly downloaded because I waited until the car reached the new fan temps and it worked as expected. The idle was also spot on to the modifications I had made.

I also surmise that within ATR it is using the *.dat files somehow. I'm not sure if that is the base map and the *.ptm I loaded is the working map. If someone knows the answer to this it would be helpful to clearly understand how the ATR processing works.

Thanks everyone for your help on this forum. It has been instrumentally helpful to keep my RX8 at the leading edge of it's performance.

The base map from cobb is supposedly supposed to be very very close to mazdas stock map, so if you noticed any changes from cobbs base map then it was definitely changes you made.

I also recommend that you might want to raise the OMP levels under load a tad bit, to me they seemed a little low.

I added 20% across the board on OMP values with a max value of 60. The cobb tables that I viewed equaled the values on my ECU OEM MSP 16 map.

So does this mean I can't use the Cobb AP with a catless exhaust? If so, no wonder I had issues. I am running the Cobb stage 1 tune and I have a turboxs catless midpipe and racing beat catback, and I installed my Cobb AP a day ago. I was driving today, and I got an engine code and I read it and it was: P2096 (Target AF feedback system too lean) so I don't really know what it is for and am hoping that there is a way to run the tune with a catless midpipe.

well If you had read anything in the forums. They all say do not use the cobb stage one. the car doesn't ahve any hp left on the table for a throw in tune. to gain anything at all it has to be a custom tune. Your exhaust won't hurt anything at all, but the cobb stage one might if you do anything mroe then light driving. The midpipe will cause you to have codes for no cat.

Oh. Well crap... Well, is there any other way to get a custom tune other than MazdaManiac? Other than tuning myself too...

You can find someone who does custom tuning or a shop that dyno tunes Cobb. I've come to find resources are limited in that. Most people stick to MM and his remote tuning sessions.

Well the thing is, I bought it used for $300, and I don't really want to spend another 300 for the tuning service

I sent you a pm

Hello evreyone im new on rx8 world and accesport world, Question? If i buy a MM accesport will that come pre-loaded with tunes or i have to down load different tunes from the web? My question is: Can i choose different tunes or i have to talk to jeff so he can tune it for me?

It will not come with a pre-loaded map (don't use the stage 1). You'll either have to tune it yourself or else have Jeff or another tuner (Kane, Brettus, etc) tune for you. Search around the tuning and major horsepower threads for tuning solutions.
If you have no knowledge of tuning, I recommend having one of the above, or a rotary knowledgeable tuner do the work for you.
And don't ask too many questions without doing some prior research on the subject...

do you still have the ATR software?

What car year and trans do you have? Cobb technically has ended support for this. But if you call they should still have the software. It won't be for long tho. I have 2004 usdm manual if you need it

I have a 2007 rx8 6 port 6 speed and a Cobb AP...

I called them they want me to pay to 150 for a class... I don't need a class to tell me how to tune a car... not my first time.

Its a CYA thing for them honestly. Its not all that bad you can skip and just take the test. Look at it as a way to get the software. I will say if you don't do it, or find another way soon you WILL not be able to get that software here in the near distant future.

The software is linked to your specific AP. You either needed to get the software from the previous owner or pay Cobb money to take the class. That's the current state of AP's unfortunately as far as I know. I tried providing my version of the software to another user here and it didn't work. If I recall correctly when I originally got my AP I had to contact Cobb with the serial number of the AP and they then sent me a link via email to DL the software.
