I have the 03 ecu for MY00 and did notice more drivability ( car use to somewhat bog at low rpm) I think the 00-01 ecus had a more rich tune compared to the 02-03 so i have the VAFC2 for WOT tuning. IF all your worried about is WOT and peak hp numbers then a vafc would be the way to go.

 

your 00 certainly runs a little richer (or should) than an 02-03. If you want to swap the ECU, the latter years should give a couple hp gain.

 

You could just leave it alone.... And not screw anything up.

 

But the codes... may come back.. then I definitely have an issue.

 

I will leave it alone for now. I will deal with it when I go FI

 

dood if the codes come back there's something wrong with your car...you get a new ecu it'll prob throw the same codes...


sorry but what a stupid diagnosis...fix your car

 

Sweetj definitely is not a "dood". She also isn't the original poster. Your sarcasm is very inappropriate.

 

Yea I never said anything about throwing codes...
