OK, i just called my dealer's service dept. and asked about the L PCM reflash. The technician didn't seem to know anything about it. But asked what it was in reference to. He asked if there was a CEL, and since i read some mention of that here on the boards, i confirmed that with him, even though i don't get a CEL.
He then said, he would have to look something up. but he obviously didn't do it then, or will not after our phone conversation.

My question is, what do i ask the dealer? or what do i refer them to in order for them to give me the L reflash? I can cite poor gas mileage, but is that enough grounds? For those of you who've received the L upgrade, please let me know how i should approach this.

One last thing, if i take my car in for the scheduled service, and ask that they also perform the dynamic damper recall, airbag recall, and the eccentric shaft memory clear, how long would that take? I guess throw the PCM reflash in there too. How long would all of this take? Given that they have the parts necessary to do the service.

Thank you.

 

Was there ever a Dyno plot for the new and improved stage one with the L flash? I keep looking and looking, let me know if I missed it.

 

To get my "L" reflash, I told them that I wasn't happy about getting 12 Mpg when the sticker stated that it would be much higher. And that I have tried many different driving styles, which is all very true. It doesn't bother me that I get the mileage that I get, but if there is an easy fix to make it more efficient, I'm all for it.

To have mine reflashed, airbag recall repaired and the mount recall repaired it took 2 hours.

hope that helps.

 

strong bad,

Well that is a huge question. To do the re-flash on your PCM only takes a couple of minutes, Passenger side air bag recall takes aprox. 20 minutes, eccentric shaft clear should also only take a few minutes, as far as the dynamic damper goes? My guess is that your car would need to be at the dealership for the day depending on how busy they are when you take it in.

 

Based on some informal conversations I've had with Maurice, those numbers are about right - but only with a catback exhaust and midpipe. I'll let him, or one of his coworkers (Like RX8 Friend) speak to the specific numbers.

 

Jeepers Fellas...

I don't remember reading where the Canadian boys claimed 40 hp on the stage 1. If you can point to that claim, I would sure like to see it. I think it still 20 ish stage 1 and who knows, stage 2. I think it was that the "L" issue was improved driveability with stage 1.

Read this thread, the information is on page 2

 

You are kinding, right? Any conclusions based on Gteck are very risky. I have a Gtech. You have to run 6-8 runs both directions to draw any conclusions. In addition, one gear runs yield better results than 1/4 mile type reviews. They are coming out with a new release, 3.1 which I hopes help, but until then, don't take Gtech results to the bank. I would think they posted these slips to give us something to ponder, rather than to state they were for sure getting 40 hp increases off the stage 1.
Tom

 

Maybe the Gtech results are not exactly accurate when compared to a real dyno or 1/4 mile run on a track but if you have plenty of baseline runs with it and, as long as it's consistent, it can be used to compare and look for any changes. That's what we are doing here and the Gtech results show an aproximate 40whp increase over baseline. We are not talking absolute numbers here, just difference between runs.

 

As neit_jnf pointed out, the G-Tech is great for relative measurement.
That said, my baseline runs were consistent with published performance numbers.
Additionally, the raw G-Tech data on G's in gear and over time allow you to draw your own conclusions about performance.
Simple HP and torque numbers are only useful to brush off the uninitiated.

 

Nope I'm not kidding. I don't own a G-tech, hell I've never even seen one. So I have no first hand knowledge of its use.

Canzoomer has never made claims based of a G-tech as being fact. At least not that I've seen.

Just looking at the Stage 1 off runs against the Stage 1 on runs shows some impresive results and that is what we are looking at.

It's not like he has taken one run and said the car is now making 280 RWHP. Its the difference to the base package and the Stage 1 that people are making the 40 HP claim.

 

I would love to hear more feedback from people who have stage 1 and then gone from the original Mazda map to "L".

Im taking my car in and am a little hesitiant to get the L flash before experiencing stage 1 with the orig Mazda map.

My stage 1 should be shipping in the next batch.

 

One interesting thing about the ecu we just found out by a member of the German forum. They contacted mazda japan.
Mazda japan reported to him that the ecu does not open fully untill 5400 to 6100km. Till then it is not possible to drive full speed on the autobahn for longer runs, and I rember myself that only for a short time I could go 253km/h, after that the car just only drove around 236km/h with the feeling something is not opening. mazda japan added dthat the airdoors open fully after that amount of kilometers.
The question is why they do that, and would it be better to istall stage 1 later if mazda thinks the car should not move with full power in the beginning. Mazda must think it will harm the car to have full power during the first 6000km This applies for german cars the rest I do not know.

That mileage issue has been talked about several times however I don't believe anyone could ever prove that is fact and not a rumor.

 

Well that person had the rx8 twice on the TÜV powercheck and reported a difference about 40hps testing around 4000km and around 6850km. for him he clearly felt it.

 

What is the conversion of kilometer to miles?

 

62MPH IS EQUIVALENT to 100km .

cheers

OK.. just for an update on the mpg for the "L" flash. I got it last week sometime and just finished up my first tank since I got it flashed and it made a big difference. All in all I went up 5 maybe 6 mpg. Before I was lucky to get to 190 miles at 3/4 tank and tonight I got to 250 at 3/4 tank. The final figures were 260 miles at 11.7 gallons.. I am totally satisfied with that... Hope all of you experience the same...

David....

 

There has been a problem with some UK cars where the actuator motor on the VFD air intake at 7250 rpm sticks. This gives a reduced acceleration effect above 7k - and lower power.

Mine had this problem tho it seems to have gone away. That was at 2k miles.

AFIK I thought the ECU doesnt know how many miles the engine has on it anyhow?

 

Excellent news davefzr...

Hope you continue to see these kind of gains!

 

Fellas...

I REALLY doubt you will see a 40 HP gain going from stock to stage 1. The Gtech runs Maurice posted were just a couple of passes run in terrible conditions. 40 HP is enough to be very noticable and the guys getting these units are reporting mild improvements. I'll be happy to get the 20 to 25 HP that Maurice was projecting off stage 1. Where are all the guys that have received their stage 1s? How about some posts with dyno results (or Gtech runs or even simple timed passes from a certain rpm) from the guys that have received their stage 1 already.
Tom

 

I dont think any customer has stage 1.1 with L map?

Anyhow CZ himself said ignore the power numbers, the GTech data was more to show the change in the power curve which is marked (and usefull), and not the actual power values themselves.

 

I just got my ECU upgraded to the "L" version today at the dealer along with that airbag recall fix. After I got home I did the test to ensure I got the upgrade (hit the brake pedal 20 times under 8 seconds) and my oil pressure guage did move from low to mid back to low.

The dealer informed me that this version has nothing to do with gas mileage and I shouldn't even notice an improvement. However most of the posts I'm reading from people who have upgraded from "K" to "L" have noticed improved gas mileage.

I have yet to fully test it since I am still on the same tank of gas since I got it flashed this morning, but I'm definately going to make a note if there are any gas mileage improvements. Maybe they don't have their facts straight but I just thought I'd make it known that I was told right from their service dept. that it doesn't affect gas mileage.

 

I called and asked my dealer about doing the airbag recall and also the PCM reflash. He said they don't know exactly what updates the reflash has on it. They just do it if the TSB calls for it. He did say they can hook it up to see what version is currently on there, at which point I'll ask to be updated to the new L. Complained about low mpg and also that I talked with N.A. Mazda and they said a reflash wouldn't hurt anything.
Taking it in this Thursday.

 

Syrenic- do you notice any power changes after the flash?
