Just some good info that might help some other people out (and save hours of tuning frustrations)...We just wrapped up a tune on a turbo 09 Scion TC. The car would hesitate hard, mostly at full throttle, though the AFRs and timing looked great. After hours of messing with the tune, I talked to Henry at AEM. I told him we were running the Z110 hex and he recommended flashing in an older version. We flashed in the Z107 file and like magic, the car ran beautiful. So for those wondering if it will work on the 09, yes it does but make sure you are running the Z107 hex.
Hope it helps. I couldn't find much info on the 09 when I searched.
did you ever try z104.hex? how is your idle on z107? do your afr's vary quit a bit in idle? does the car sometimes die when comeing to a stop or starting at a stop? is throttle a bit more laggy than stock?
