2013 ZL1
A6 Transmission
Upper and lower Pulley set. Ported blower.
His shifting is really goofy, pulling timing where it shouldn't be. Under REALLY light throttle.
I think I know where the problem is, but I can't get EFI to datalog "RPM vs EQ Ratio".
Sorry for the lame picture. But I can get the vehicle to datalog RPM just fine (obviously). But the EQ Ratio, I can't find it anywhere amongst the PID's.
Any thoughts?
