Hi All,

I have 08 JK and just installed Teraflex 4" lift and 37" Toyos this week. New gears and drivelines are going to be installed in two weeks, but I am currently using the stock 3:73s. I have both the AccuPro and ProCal programmers and am trying to use them to set the tire size from 31 to 36.5. When I uses either of them to do that, my speedometer stops working. Using either, the programming says it has successfully made the updates and there are no errors. But each time the speedometer needle just sits limp and no longer moves.

The only way to get the speedometer to work again is to set the tire size back down to 31 on the AccuPro, or to reset back to factory defaults using the ProCal.

Has anybody seen this before?

BTW, if you wondering why I have both it is because I bought the AccuPro a few months ago, and then the ProCal came out and I wanted it to disable TPMS. I wish the AccuPro had the same features as the ProCal because it easier to use, but it lacks all the cool things the ProCal does with those goofy little dip switches.

Thanks in advance for your feedback!

 

Did you turn the key to on before plugging in the module? That happened to me when I plugged the module in first. Also I needed to turn it to the on (2 clicks in) and not just the accessory.

 

Thanks guys. I found the AEV ProCal solution on the forums over at AEV.

I still cannot get the AccuPro to work and not sure why. But I am good to go now.
