    Default Lost my cold start Fast idle after installing EFI Live.

    Any one come up with any answers on why some of us lost the cold start fast idle after tuning out trucks.

    I had with the H&S mini max but when I went back to stock and install a tune with my V2 it no longer worked. I don't see any were in the tuning where we can adjust the cold start idle. Just the base idle!

    Do you have the steering wheel buttons to turn it back on ?

    I thought I saw somewhere that it had to be "flashed in" by the dealer. Meaning it is a part of the calibration not currently accessible, if you built your tune on a base file that has it, it will work but not otherwise.

    Everytime you flash the ECM or the vehicle loses power, this needs to be turned back on.

    Here you go.
