This says any outdated EGS53 TCM will be automatically updated before tuning.
The problem I have is that the EGS53 is the newer version. Is this a typo?
I have tried this on FOUR EGS52 TCM's and it has read them and will write one time, thats it. After that I get 7x writer error codes.
I've tried it on THREE EGS53 TCM's and it works fine, can read, write, etc.
Can an '06 that had a 52 be upgraded to a 53 with no problems?
The only difference I see is an added PWM Solenoid tab under the General tab and 27 tabs for the torque converter under Toque Management.
I pretty much wasted four tcm's because of some problem. In my other thread is was assumed it was my 13 year old tcm, or wiring, or laptop, it CAN'T be hptuners. WELL WHY DOES IT WORK WITH THE EGS53?
Who would have 7 TMC's laying around? I do. I'm not running a shop either.
