i have a couple of questions is it possible to edit the tune in the tuner with a computer? does anyone know what the ajustments are on the tune? like what was changed like what the timing was changed to and so on.
Tune parameters are only adjustable with the handheld unit itself. The only way I know of to see what changes the tune makes is to datalog, and I don't think the Superchips 1725 tuner does that.
