So If i reset the ecu with my mods...

:
Yellow 2003.5 MSP!
...which is just an SRI, catless midpipe, and bov, and i dont have any piggyback controllers, the ecu will reporgram itself automatically to run correctly (or as properly as it can) to those mods as I go through my car cycle correct?

How acurate would it be if im correct?
 
you should always reset ecu after installing a mod, the change in air flow has to be known by the ecu so it has to relearn fuel maps

Does the same apply for my test pipe?

its a good idea, but the ECU tunes by the primary O2 trim anyways.

lol i had a feeling youd be one of the guys answering this question. You seem to have an answer to many thinks lol. anyways thanks man (or woman... cant tell behind a computer)
 
Really no need to rest since the ECU is constantly relearning. I would however take her on a bit of drive but don't mash the gas too much depending on what you installed, the last thing you want is to go too lean ect, although that would be hard to do since the factory tune is pig rich.
 
pretty sure he is a guy lol
Haha yeah i just dont wanna discriminate. Sorry yudkib i dont mean any disrespect. I included "woman" cuz my girl is a down ass little grease monkey. I love it too cuz she can fit place where i cant.

Yeah thats what im thinkin too. Im a ctually hoping that it does lean out the car a little bit but not too much. In need to pick myself up an Air fuel ratio gauge.

For the mods, I just put put a filter on the MAF instead of the airbox and a catless midpipe oh and a dual port bov, the ones that arent suppose to stall you car. I havent actually tried any of my mods yet because my lsd still hasnt come in so my transmission is just chillin in my garage. Its funny cuz i hactually have a picture of my brother standing in my engine bay with a nice little thumbs up
