HI! An old member returning, seeing whats up with everyone. Noticed tracker is nowa moderator, lol aint that somethin'? I own an 06 mazda3 sedan 2.0 autotragic w/slap stick(uber slow). Havent modded, might in the future though depending on the answer to this question-"after adding to performance mods, will the computer relearn and correct itself and go back to stock power?" let the post-whoring commence!

 

14.7:1 is the perfect air/fuel ratio and the PCM is programed to achieve that by various inputs and outputs. The PCM has perameters and not fixed settings persay. So say if you gave it more air it would compensate and you would still have more power. Give it headers and better flow it will add more power and not compromise the PCM's goal of achieving 14.7:1 air/fuel ratio. There is a point that you can go past the abilities of the PCM's parameters.It can only advance/retard the timing,change the injector dwell so far. Really depends on what you do and how far you go. You can trick the system to do what you want up to a point.

 

Awesome, thanks. the only problem i have now is that i cant afford the upgrades i had my eyes on when i WAS making money. Back when this forum was new, everyone told me that it was pointless to do upgrades because it'll go back to stock after a few hundred miles[:@][:@][:@]. Now since i know, im definately opting for a new exhaust system, since im close to running out on my warranty

 

wow you still have a warranty on a 2006. thats interesting. actually the principal of my high school has a 2006 mazda3 as well. he thinks its the greatest car in the world. and i told him i had a 2008 he looked at me funny lol. anyway welcome back even though i never met you before but maybe now i will haha.

 

am i not suppose to have one?[sm=dontgetit.gif]

 

That's only 2 model years ago Jaime, andprobably less in time driven/owned.

Krim, I believe you have the 3yr/32K warranty on the '06 models, right? You probably have about half of that left, unless you've racked up the miles?
The earlier models, like mine, had a 4yr/50K, but I think it was '06 when they reduced that and started getting stingier.

 

well just the fact that i didnt think that it was still under warranty. probably because i figure that that was 2 years ago and the mileage has surpased is mark. but then again i am probably wrong

 

i have an 05 MazdaS that is still under warranty...time will expire long before my miles will be up. Currently the car has 13,974 miles and was purchased brand new in June 2005.I split time in the car with 2 motorcycles...Harley Road Kingand Yamaha R1!!

 

yea its all about how much you drive. me personally have had the car for about 3 and a half weeks and im at roughly 2200 KM hehe. bought it with 2.

 

Actuallyi think i have the 4yr/50Kmile warranty. I could be wrong, but thats what it says on the sticker IIRC. gotta look at it again(still have it, lol). I have 29K about to be 30K. Eh, virgin, are you apart of another forum underneath another name? Im a ninja you know, so dont lie! i'll karate chop you 5 times dead before you hit the ground!!!!11!!1
