Yes I would remove all traces of any programmer before going in for any type of dealer service, it honestly only takes mins as @Rhinebeck01 has pointed out.I just upgraded my wheels and tires for 33” on 17” wheels on JLU Sport S and I am curious about that I need to program to put 33” tires on computer?
If I do, then I want to use Tazer JL product.
Do we need to disconnect even we going for regular maintain services as well? Like oil changes? Sorry This is my first Jeep and I am new to modifying.
As far as tire sizing goes this is what I did when going to 315’s from my stock Sahara tires.
1. Measure the height of tire while sitting on a flat surface ( mine came out right at 34” )
2. Turn vehicle to run position but don’t start engine
3. Go into the Perf setting and from there select the tire size using the up/down arrows and then select ok to accept it.
4. DL a GPS speed app to your phone and then compare the two speeds and adjust the tire size with the Tazer accordingly.
My speed was off by 5 MPH with the tire size set at 34” so I just kept bumping up my setting one selection at a time ( testing after each one ) and ended up at 34.49” I believe and it’s spot on perfect from 70 MPH and down
