A few months back I got the MM3 with engine/tcm tunes. Just got around to installing it the other day for a variety of reasons .. .Got the error message on install due to the fact there was previous tunes installed. I got the stock recovery file from MM3.
1) is there any way to save whatever tuning I have in there now before proceeding?
2) is the tuning saved in the vehicles modules once installed, like if somebody tore out the mm3?
3) I have a five position rotary switch mounted in the dash from the previous setup. What does it take to use that to change the tunes level on the MM3? I have the full package so there's different power levels available and it would be nice to be able to turn the knob as opposed to strolling through the display.
Thanks for your input!
