    Maximum Engine Torque PID

    Hello,

    I have a problem while tuning 2012 Camaro V6 E39 with IPF Supercharger kit.
    The Throttle seems not fully open until 4000-4300 RPM.
    As I figured out the "Maximum Engine Torque" PID shows lower value than "Engine Torque" PID.
    So I'm trying to find out what table or option is setting this PID ("Max Engine Trq").
    I've tried to change almost all tables of "Torque Management" section.
    I have attached the log file, please look at the end of this log, and watch the "ETC Position", "Engine Torque", "Maximum Engine Torque" PIDs

    Thanks guys!

    I would also like to understand the Max Torque PID better (have asked the same question, but haven't received any answers). I wonder if it's somehow based off of the Peak Torque table values? I have read that you should NOT max-out the Peak Torque table like some do (at the very least, it can cause PE to never enable - and may have other side-effects as well). In case you haven't already, do some searches on "Peak Torque" and "Driver Demand" - they both seem related to this discussion and there is some good information out there about them (although, a lot of questions remain as well).
