Asking Dealership to update my computer tire size from 31 to 34, does that void certified powertrain warranty?

Very Similar as the Flash Cal I installed

I have at least 1 local dealer that can't/ do it cause they can't find a billable code?? Some people say they may not have paid a license to do it??? Weird. That's on 23 Sport ( from 245/70 to Rubicon take offs). As it turned out, the speedo is fine when comparing to GPS app on phone.

If you can, re-flash it. I ran my wrangler on larger tires and a re-gear for several years. After the reset it runs better because it has correct data. The dealership knows you've changed stuff so they can claim the incorrect computer settings affect true mileage and other things

You will pay the dealer what it would cost to buy a Jscan setup. It has been reported that some dealers will no longer do this.

The warranty issues will come later, if you try to make a drive train related claim and get a bad dealer that wants to blame it on the non-factory wheels and tires.

That would be a very difficult sell in court though, considering 35's are a factory option and 37's are incredibly common in the aftermarket with little trouble

Yeah, but how long would it take to get it to court, and how much would it cost? Some dealers are very accommodating, and some will look for any reason to not do warranty work.

My dealer did it for me. No big deal.
cost me about $125.00.
I do not want or need a Jscan or tazer

Basically I swapped from the stock wheels to heavier offroad tires, and I've run into issues hitting potholes causing traction/transmission issues, I know I need to update the computer but I'm afraid of going to the dealership to do it as I have the certified warranty. Should I wait the week or two for tazer or go to the dealership?

My dealer wouldn't do it, but I did it myself.
