So I regard my 3.6L auto JKU Rubicon to 5.13 for 37" tires. After regearing the vehicle went into limp mode. I've tried adjusting the wheel size and gear ratio to represent the changes but it continues to go into limp mode. Tried to research the answer as the new Trail Dash states it is compatible with 2012. Anyone have experience with the Superchips Trail Dash? If so how did you get it to work? I found once source that suggested having the dealer re-flash the computer and then set the gear ratio prior to driving it, anyone with first hand experience. Planned to test out my 37" tires but this limp mode may prevent me from making my trip this Wednesday.

Go to their website and see if your trail dash needs to be updated to work with the 3.6, they have the same part number for the 07' and up

Are you sure the limp mode is being caused by the gearing and isnt something like a disconnect on a sensor?

For anyone else, my solution was AEV Procal. Worked in under 2 minutes!

Sensor shouldn't put it in limp mode. plenty of JK driving around with broken sensors. It will just show the abs light for repair.

Have you got this fixed? Should be able to set it back to factory settings then reset it to your current set up. If that dont work than a tripto the dealerwill be needed.
