Just lifted and swapped 4.88 gears and 37s on 21 Rubicon 4xe first time swapping gears with the 4xe. Iv tried jl tazer and superchips neither works. Tazer has the options for tire and gear ratio but immediately sets off stability control and abs lights as soon as you enter the options. Its got the latest update 11.3.0 as of 9/1/21 guys at tazer don't have a fix yet. Superchips wont even connect at all. Anyone else got any ideas? I've done the same setup with the tazer on the normal 3.6 and 2.0 30-40 times without issues.

There is a discussion on this on the JL Wrangler forums.

I don’t think any programmer does gearing changes yet.

Yea I too have been patiently waiting. Went ahead and threw on 35 in the meantime this gets sorted out. Since we have a JK on 40's having the 4xe on 35 is fine until its not.
