I was told there is a way to reset the factory tune in my Diablo handheld to save my modified tune. Is this true, has anyone accomplished this? I need a way to have my tune saved and make rpm changes if needed at the track.

 

Not sure what you are trying to do exactly.
If you have a custom tune on the PCM, and want to modify it through the Predator, thats fine assuming the Predator is unlocked.

Thanks

Yes i have a custom tune that i want to save and be able to modify at the track if i have to, such as shift points, RPM, MPH and maybe Fuel trim. I put my car back to factory tune, then loaded my custom tune back in the car and saved it as the factory tune in the Diablo. It looks like it worked. It showed the correct shift points and rpm.
