The Official Superchips Forum

I have a 2005 Jeep Wrangler Unlimited LJ with 4:88 r&p and 35" tires. I saved for months to get a flashpaq so I can reprogram for tire size. I looked at all the information I could find. Called local 4x4 shop as well as quadratec and both said the 3875 will allow me to do this. Today it arrived in the mail. Wated all day to get home and try it and it says "Rubicon models only" I have never read that in any article, did not see it in any discription. Do you sell a programer that will work with my LJ? Guess its time to start saving again for something that might actually help.

Welcome to Superchip's forum!!


Where did you read Rubi's only?

Does this Jeep have a ABS module?
If it does, then it can recalibrate for gear and tires.

If you don't have a ABS module, their is nothing to program.

If you do not have a ABS mod. then all you need is a (speedo gear).

I hit the same message when trying to adjust for 33" tires on my 2005 Wranlger LJ Unlimited. It says this option is only available on the Rubicon models, or something similar. For the ABS are you talking about the brakes? I don't remember if I have ABS brakes, so how can I tell? Regardless, I got the Rubicon only message. When it saved the factory settings it saved 2 files, and when I loaded the "87 Octane", it loaded 2 files. Any other way to get this to work on my Unlimited with 4" lift and 33" BFGs? Thanks

Try going to the stand alone features in advanced features area.
See if it will adjust the tires and or gears in that area.
