Lost my cold start Fast idle after installing EFI Live.

[Dragbear]

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.

Just went thru this last night I had to turn it back on in the dash.

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

Here you go.
