Mazda Reflashed my ECU, Now I Am Not Getting a Black Tailpipe!

[alien1979]

You read it right. I took my Speed3 in for some warranty work and asked them if there was an updated program for the ECU. They did find one and reflashed it. I was complaining to them that the boost seemed very irregular. One day the car was fast as hell. The next, nada.

I picked it up a week ago, and the tailpipe is still clean. Before, the pipe would turn black after one day of driving.

Any thoughts or conclusions? Did they accidentally install the MS CAI program?

P.S. The car does feel a bit more torquey, but without dyno proof its subjective at best.

According to this thread, Josh at RonTonkinMazda says that there is not ECU reflash. Who is your dealer?

i emailed mazda we have done one and have not been told about any reflash so i should find out for sure if there is one or not.

****There is no reflash for the MS CAI and if your dealer says there is they are wrong**** What dealer said there was a reflash?

my dealer is courtesy imports, out in vegas and they have it...it is to fix teh a/f mixture through out the rpm range...i have my appt tomorrow morning

there is a reflash for the p2006 code not for the ms cai

 

[SwampAss]

after I installed my CAI, my soot problem has been cut down drastically. I haven't been the dealer since my P2006 code back in Jan.

Jeff Haas Mazda in Houston, TX. Update F0010XFX 0.3.

I had a chance to ring it out this evening and the car really does feel faster. On top of that, it was somewhat humid today, which typically the car feels slower on days like this.

Please reread my post. I DO NOT have a CAI. I only asked the dealer about a reflash since I was having intermittent problems with boost. Sometimes the car just didnt feel that fast. So far it feels pretty damn good with this version of the ECU software (nee firmware).

Doh, I thought that was the update number. That number is just the job code for Mazda. Sorry.

reread mine. I didn't say you did. Just noting similar results with no "update".

Wasnt directed at you, smartass. Oh, I mean Swampass. (poke)

Damn donkeys getting smart all of a sudden.

Tailpipe is still pretty clean. Wish they had put the actual update version on my invoice.

The dealers are cost driven. Mazda will only reimburse them for warranty work thet they deem was a fault in design or bad part. Distinguishing this from environmental issues or abuse is difficult, so they choose to take the "guilty until proven innocent" approach. Blindly or half winked doing a re-flash for someone is a risk in accrued cost to the dealer. The re-flash they have now is for people complaining about power fluctuations. If you want the re-flash but don't necessarily have the symptoms, they wont do it or even admit they have it to avoid causing more drivability problems in the future....i.e. more cost.

man it's like deja vu all over again like with the msp

 

[alien1979]

so the bottom line is that we have to wait for the aftermarket to tune the damn engine correctly? dont get me wrong, if my car never made any more hp, I would be happy. Its not bad out of the box. But when you have past experience like many of us have with the potential of certain cars, it makes it hard to say no.

The black soot problem you're experiencing is due to your AF ratio being too rich. You're dumping fuel if that's happening.

 

[Mr.Jake]

My car has been doing the same thing lately. It seems to haul ass one day then the next day my moms sunfire would kill it. Right now it has not been holding boost, ( thats what it feels like anyway) I thought it was a bad turbo xs valve again, but the stock one didnt really change anything. I though it was something I did, but this kinda makes me thinkg now.

I realize you are trying to be helpful, but I am quite aware of what causes the tailpipe to be black. I didnt want to come on this board spouting off about what I do and dont know.

That being said, I come to these forums for help and knowledge and appreciate all that I have gotten.

This is my first turbo car and I wasnt aware that the OEMs set them up to run this rich. I realize they need to account for anything the car might see environmentally, but this seems to be excessive.

Whatever software (firmware) they loaded seems to have helped the car immensely. I only wish I could provide the group with a number to identify it.

What kind of gas are you putting in the car? If it's not 93 octane that could be the problem.
