What kind of ecu does the new evo use? Is it one that learns and adjusts to conditions? I currently have a celica gts. When you install S-afc and tune it, after a week it will go back to factory settings on the ecu. So you pretty much have to tune every week. This is why many celica owners do not use the s-afc. I plan on getting an evo within a week.

 

i believe similar problems have been asked of the evo before and the general agreement was that the evo doesn't adjust for the SAFC. Tricking the air flow sensor seems to work just fine.

 

Excellent!
