    Throttle 100% with pedal 30% in 0 VSS

    I'm struggling to solve trouble shooting now. Need your warm help.

    I just install the LT4 supercharger on my 2017 Chevy Camaro LT1 V8 NA 8speed AT which taken off the blower from other Camaro LT1 to LT4 conversion.
    I knew I have to break out the air temp signal from T-map sensor. But didn't yet.

    Try to cranking and snatching the gas pedal a little bit on idle RPM. Probably pedal position Max 30%. But, TPS suddenly goes up 99% and DTC came out P0100 & P0106 & P0068

    Can you review the log file(1min 18sec point) and hpt on my car?
    I don't know why driver pedal torque request goes up till 27000Nm suddenly compare to low pedal position.

    +1 on this, but on v6 I'm 99% sure the issue is in the Driver Demand tables being inconsistent after going FI from NA. I have the car in the paint shop for the week, after that I'll upload the update done with the DD tool and report if it will fix the issue
