Here's the reset procedure: http://www.quadratec.com/jeep_knowle...article-89.htm

If I were you I would do it in this order:

1) Unmarry the Trinity (install original backup tune).
2) perform the factory reset procedure.
3) double check that the Trinity is really updated. Some updates cannot be applied while the Trinity is "married" to a vehicle.
4) double check that you have the latest tune from RIPP.
5) install the RIPP tune.


I really doubt the factory reset will have any affect. It mostly resets things like long term adaptive memory (fuel trims, etc). I know for a fact that long term fuel trims are already reset every time you install a tune. But you might as well do it just to be sure you are starting fresh with everything.
