I"m interested in this. I can easily do the math while driving and to calculate fuel economy, but I'd like to accurately keep track of overall miles with the odometer.
I just downloaded and read the installation manual. Did you install yourself? IF so what Option did you use and where did you mount it?

I was all excited when I saw this thread as the new tires and wheels I just added have caused the speedo to be off my 2MPH according to the GPS.....I think for 2MOH I'll just do the math in my head instead of spending another hundy that I could use for something else that will allow me to have some more fun

There are several electronic speedometer calibrators out there with one popular model being the Truspeed. I'll post more info on that tonight with another less costly calibrator as an alternative to the more expensive Truspeed.
Only non-Rubicon transfer cases have a speedometer gear that can be changed to calibrate the speedometer. Rubicon transfer cases don't have speedometer gears, Rubicon speedometers can only be recalibrated electronically.

|jgorm||I'm a diablo dealer and I, nor diablo techs, could get the tire size change to work on my jeep. I think its called a speedcal to interface on the signal. I'm not sure there is another way.|

|jasongind||Re-gearing is your best option to correct speedo on a Rubi, that's what I as told. There is a programmer, cannot remember the name off hand, but it cost like $380 and once connected to a vehicle it can only be used with that one.|

|f9k9||Many dealer techs have difficulty in programming for the correction of different gearing and tire sizes in the 03-06 Rubis. It's hit and miss and if, you aren't in tight with your local dealer, the costs could add up. Personally, I prefer a speedo correction device and you have many to choose from. I prefer the Yellow box. I can correct for tire sizes, tire wear and gears.|

|jkp||There is not a speedo gear on the Rubi Tcase.|

|biggie||Personally, I haven't checked. This is what I've been told. I am familiar with the the 231 case and gear changing options on it. Everything I've forund so far leads me to believe that there is a signal generator on the T-case and the ECU is programmed to interpret the signal based on other variables like axle ratio, tire size. etc.|

Do you not have a speedo gear on x-fer case?

Recalibrate of '05 Rubicon Speedo
I know it's been asked before but does anyone know the procedure to recalibrate the speedo in a '05 Rubicon without using aftermarket correction devices? I've heard that it needs to be done via programming as opposed to 231 equipped models, that require a speedo gear change. I've been told that factory parameters allow for up to 35" tires. Mine are 33's. The local chrysler/Jeep dealer has not been able to do it and they are supposed to be in contact with tech support for the correct procedure. It's only been a couple days but they do not have a procedure yet. thanks.-TB
