I thought i had read somewhere that the procal can take away the tpms sensors, or make it so the light does not come on. Does anyone know if thats true?

Yes, you can manually set the sensors to "0" so the light will not come on....

Not sure what year Jeep you have, you should fill out your info

For 08-10 for sure. I think for 2011 as well. I don't think 07 had TPMS
Not sure if they have gotten the procal to work on 2012s yet.

Oh. I forgot to mention that. Its a 2011 unlimited rubicon

AEV's ProCal Module is a hand-held powerhouse! This essential tool provides JK owners an easy, low-cost way to make a variety of useful changes not offered by the dealer or any other re-programmer. Topping the list is the ability to correct the speedometer and gear ratio when larger tires are installed. When the speedometer is left uncorrected, there is a major degradation in the performance of the stability control (ESP), transmission shifting, and engine performance.

The best part of the ProCal is that it isn’t just for correcting the speedometer. The Tire Pressure Monitoring System can now be recalibrated to better suit aftermarket tires without triggering the dash light. Further, the ProCal Module makes it possible to activate daytime running lamps, “one-touch” turn signals, enable a temporarily increased engine idle speed for winching, clear engine codes, and even has a feature to help alignment technicians align the vehicle perfectly for optimal ESP performance.

The ProCal Module is equipped with a series of easy-to-use DIP switches. By reading the simple Quick Reference Guide included with the ProCal module, a user can quickly dial in a code for the desired recalibration. Once the DIP switches are set, simply plug the Module into the vehicle's OBDII. The whole process can be completed in mere minutes and it's just as easy to restore the vehicle back to its original settings with the ProCal.

Please note:

The AEV ProCal will enable axle gear ratio changes to be made to Wranglers equipped with the A580 Automatic transmission (2011+ 2.8L, 2012+ 3.6L)
The AEV ProCal cannot change axle gear ratios for 2011+ 2.8L CRD diesel Wranglers with manual transmissions. See more in the FAQ.
Key Features:

• Correct speedometer
• "One touch" turn signals
• Clear engine codes
• Easy to use DIP switches
• Recalibrate tire pressure monitor
• Increase engine idle speed
• Optimize ESP performance

You can set it to zero and the light does goes out. I have a 2011 and I have done it.
