I am new to this forum as well as owning a modified jeep.
I have read some other threads but still was confused about re-calibrating.
I have a 2016 JKU automatic. I put a 3.5" and added 35x12.50x17R. Have read and understand that the recalibrating is important for odometer as well as your shift points. My question is regarding a specific product.
Does the FLASHCAL PROGRAMMER (about $150-170 US) automatically adjust the shift points when you adjust the tire size or to accomplish this do you have to go all the way to the Flashpaq?
