VersaTune User Forum

Hi !

I have latest version of versatuner installed to my car, and I wonder - can I upgrade TCM callibrations using IDS with VersaTuner installed ? Should I revert my car to stock firmware ?

We don't touch TCM calibrations, so you are free to update them. It should work with VersaTuner installed. If it doesn't it's changing something in the engine ECU too, in such case we would need to look into it.

Follow_me8, what are you using to tune the TCM...ive been looking at this for some time and found nothing (except maybe for TCM-2000 : https://www.powertraincontrolsolutions. ... Controller )

Thanks
