Part of it could be in your Virtual Torque. A higher flowing TB could be indicating too much airflow to the ECM, and it could be pulling timing as a result. Making adjustments, at commanded timing, at that cam angle, could help with this. I'd log and look at ZERO PEDAL TQ, too, and make adjustments from there, if necessary. It should be close to ZERO. I'd, first, make sure the airflow model is correct.

JMHO.

I am seeing around -6 to -12 at idle. All this virtual torque stuff is mind melting just to restore proper drivability. Maybe the Soler TB was a bad idea. I do think that my airflow model has been off for a while though, definitely even before I put it on. I think this just sort of exacerbated an issue that was already there.
