PROCAL MODULE Sold Separately 

*** PROCAL MODULE Sold Separately ***

All 2018+ model year FCA vehicles have a new security feature that was implemented to prevent the OBD-II diagnostic port from being used for aftermarket recalibration tools and performance tuners.

The 2018+ Ram ProCal Module includes AEV’s Bypass Harness kit. This kit will bypass the new security feature, allowing the vehicle to be properly recalibrated by the end user, instead of having to take it to a dealership and potentially being flagged for aftermarket modifications. Installation takes less than 5 minutes with no permanent modifications to the vehicle.

  • Easy to use DIP switches
  • Recalibrate speedometer for larger tires (up to 48″ tall)
  • Recalibrate TPMS*
  • Axle gear ratio recalibration (3.21-4.88)
  • Turn one-touch lane change on/off
  • Turn fog lights with high beams on/off (off-road use only)
  • Optimizes ESP performance
  • Will not interfere with most performance modules or tuners
