I have a customers 2020 charger scat pack.
pulled stock pcm, sent to hpt to be unlocked
PCM came back friday.
Swapped pcm, and pulled car from the other side of the parking lot to get close enough for internet.
Realized i forgot to install the bypass cable.
Went home for weekend
get to the shop this am, install bypass cable, pull factory read file, build base tune, load tune, car starts but will not go into gear. Load factory cal file back and no change. Engine starts, runs, but no shift out of park (shifter will move, but no gear change)
Tried removing bypass cable, same result
Swapped bypass cable with another, still same result.
I told customer his car should be finished around lunch but thats not going to happen now
Any idea what happened? Any idea how to fix?
