Sorry if this has been covered or in the wrong area.
New to HPT so I apologize for being somewhat inept at this.
2009 SRT Challenger.
I cannot get the TCM tune to take. The PCM tune loads no problem, but noticed nothing ever changes with the trans so I am digging in.
It spends time loading, and it looks like all is going well but when I go back and upload the TCM tune back into the laptop a while later and do a compare it is still stock. Hmmm Note the mismatch.
I cycle the ignition as required after it allegedly loads. Even tried opening the door for 30 seconds after I cycled it as the Tuning School states in their paperwork, which turns out to be of little help in my application.
The laptop powered with its 110v charger when connected to the vehicle.
VCM editor 4.10.5 and and the previous version didn't work either.
I do have a debug.dat file if that is of any use.
Thank you in advance for any ideas. It is an EGS53 TCM.
