That's great and all but while I don't worry about taking my FlashCal'ed Jeep into the dealership for an oil change, etc. I would probably reset if I were going in for something more serious like something going wacko in the electronics somewhere (IE anything that could be related to a CPU issue) because if they go in and see that something was changed via an aftermarket product, Chrysler will use that as an excuse to void the warranty and give you the finger. Not every dealership would do this (some dealerships are really nice/customer friendly) but to have work done under warranty, the dealership has to have someone from Chrysler come look at it to say yea or nea. Those people are usually sticklers. Case in point, a guy I heard about/saw a video of had a brand new 2012 JKUR that he bought built up form a dealership with all the fixins; big tires, wheels, 4" lift, fenders, roof basket, bumpers, etc. With 7k miles on it, something broke in the front axle (idr what to be honest) BUT since the warranty clerk dude works for Chrysler and gets paid by them, not the dealership, the owner of the now broken 7k mile JKUR got f*cked. He claimed that he never took it off road which I'd believe cause the dude looked like the mall crawler type. If it were still stock or just had different tires I'm sure they would've said "Yes this is a defect from Chrysler, please let us fix this for you" but since it was built, thats their chance to say "Nope you changed too much, you'll have to pay for this yourself." Same thing can happen here...if it's a problem with your CPU, and they go and see you changed it via a aftermarket product, they'll be swift to give you the finger and blame the reason on the FlashCal/ProCal/whatever.
