The calibration is just disabling rev hang and enabling pedal follower, so the engine behavior itself should not really change.
In the engine diagnosis tab I set P6065 to "no MIL light" to hopefully fix it, but that did not help.
I also tried scanning for the code in VCM Scanner, but it reported no DTC codes.
Is there anything else I should look into? Is there any more information that I could provide to help figure this out?
Thanks in advance
