I want to go back to my original tune that I saved when I first started tuning the car. However I have since upgraded to the RTT OS and now when I try to flash by writing calibration only it tells me the VCM doesn't have the correct OS. Do I need to write entire to fix this? I kind of afraid to to do it with all the warning and such.
Write entire, since it's a different OS.
Best regards,
Bill
