Device to use for fixing speedometer

[Anchored626]

Does anyone know if the z automotive z tzr jlm tazer jl mini programmer will work for a 2019 Wrangler Sahara to fix the speedometer after bigger tires? Shows it may also be able to do a lot more as well that may be helpful. If so is there anything else you need to make it work? Thank you

Yes, that's one of many things you can do with the Tazer JL Mini.

It's advisable to also get the extension cable.

The superchips one also does this but most people buy the tazer. I have the superchips one because it came in jeep when we bought it.

Yes the Tazer Jl Mini $$$, or JSCAN $, will both do what you need. Tazer SGW extension harness is highly recommended in either case. You will thank @Ratbert later for his suggestion.
