Dealership can now reprogram / calibrate speedometer and odometer for bigger tires

[Shak14]

Get OBD Jscan App, 12+8 Chrysler bypass wires and OBD2 bluetooth adapter (total cost of $75 for all to your door)

Save your self time and money ... and sanity

Also will be able to program your tire pressure (set mine to give out warning at 20spi) and anything else that Tazer does.

Where did you set your tire pressure?

Yep, got that far. I set the light load inflation to 25 and still getting a warning because my tires are at 30

So, I have a 2020 Rubicon JLU which has 35's. My plan in the very near future is to regear. Discussed this with my local dealer. The service manager and myself watched the video. He allowed me to watch him walk through this process to change to my proposed new gearing and the 35's.

Everything was fine until he tried to input the new gear ration. The option for the gear ratio and change in transfer case ration is not an option. We selected the new tire size and selected the tire as remaining an OEM size and the option to change gear ratio is simply not there.

I understand that a Tazer can make these changes for me, but at this point I prefer that a dealership make these changes.

Any thoughts?
