Hello, could anyone please tell me what they would recommend on re- calibrating my speedometer. I have installed new 35'X18 rims and tires and im looking to get my speedo correct!!
Went to the dealer and they told me they can only recalibrate factory oversize tires that they sell! Just not sure what unit is best to do this !!
All help is appreciated !! Thanks!!

 

Aev Procal is cheapest and one of the best options. Lets you adjust many things beyond tire size. About $140 new I think but you can usually get one used off the for sale section.

If you want to adjust power settings then look for a tuner like superchips or bullydog or hypertech.

 

I bought an aeroforce interceptor gauge for the obdII port. Works great and doesn't lock to the vin, so you can fix your friends rides too. It doesn't do performance changes though. It does do high idle for winching and disabling the traction control. I think I paid 250.

 

X2. The procal will give you the basic calibration features and be inexpensive, while a tuner will allow you to get more performance at a higher cost.

 

AEV Pro Cal is more of a Calibration tool than a Tuner. I like the simplicity of the unit. Very user friendly. I would recommend it to almost any Jeeper

 

Can't go wrong with the procal. I wouldn't waste money on 550 dollar tuner for 5-6 peak power on a tuner

 

I agree x2
