Has anyone out their used their ST3 or Powergate on another car?? I have my stock file plus two modified maps saved on my laptop and was wondering if i could get the maps for my friends S3 and saved them onto his laptop. I no the device would need resetting to put the new car's maps on but surely if my files are saved then its just a case of resetting the device after he has finished and saving my maps back onto it. Can anyone help?????
