With this setup is it truly on the fly tuning? What I mean is when i first hook up the programmer does it install all 5 tunes into my ECM and then I dont have to have it plugged in anymore to use my tunes?
Only if you want your speedo to be accurate, you'd still need separate tuning for the TCM.
One of the only downfalls to the auto-cal is you can't make any adjustments from it, they have to be made from the V2 master suite that it was originally programmed by
