But cloning the tune clones all the data still right? I want to keep my stock PCM stock and just get another PCM to tinker with so if something goes wrong, or I send it out and the tune isn't working for my car, I have a quick swap backup.


yes for all intensive purposes, done right, you end up with something that the car/diagnostic equipment cant tell the difference in.

im using a 97 ssei sc/65e file on a 97 bonnie sse with the hydrostatic 60e PCM with just some changes.

as an aside...one local's 02 gt had an odd hardware number pcm and constant knock intermittent idle missfire issues. (when swapping everything including the motor doesnt change anything you look elsewhere...) switching to a 7440 cured all ills. odd thing is he bought it nearly new, completely stock. so always check your pcm numbers
