Car is C7 Z. Upgraded to a ported blower and a Katech 103. Nice increase in power but then I noticed something off. Idle timing is now only 3 degrees, Delivered engine torque is now in the negatives, torque management advance is around 26 degrees and base advance is around 29. Before the TB delivered engine torque was around 15-20, and torque management advance was 7. I've played with ETC scaler, no change, halved and doubled idle external load, speed control reserve and timing went up a few degrees. Played with virtual torque in the idle region and delivered engine torque increased but no effect on idle timing. Any idea on how to tackle this?
TIA!
