That's funny because I'm thinking of going to OEM ECU to gain drivability!

 

I've gotten mine to not sputter between shifts and to idle much better, except after start, I ALWAYS have to hold the throttle down for about a minute and then gradually let off for it to not die.
The problem is now that it's not consistent. Some times a shift will be perfect, the AFRs will almost stay right where they are and other times it'll go dead lean and buck like it normally does. I don't know if its the tps sensitivity, pump sustain, dtps trigger, accel modifier table... something is probably just off.

 

I can recall my car running much better with fewer problems when I was using my old Autronics a while back. My AFR's stayed the same, my car idled much better, and the overall drivability was better. I haven't been as happy with the car since going back to my ECU. That thing brought several Gremlins along with it that over the past couple of years now have not been resolved. I was told to go Speed Density which I did for a while and the car did fine except for massive backfires when shifting as well as leaning out badly at times while under boost. The car has been retuned repeatedly and the problems still remain. So I figured I'd go back to a standalone
and try AEM this time around.
