OVERVIEW
The AEV ProCal SNAP is a simple, easy to use electronic
recalibration module for Ram Truck. ProCal SNAP has
the ability to recalibrate your vehicle’s speedometer to
compensate for non-factory tire sizes, replacement axle gear
ratios and aftermarket or dierent transfer case gear ratios by
simply plugging into the OBDII diagnostic port and inputting
the numerical values using the stereo’s audio equalizer.
PLEASE read these instructions completely before
attempting to use this module. Follow these order of
operations:
1. Install the included AEV ProCal Harness using instructions
from aev-conversions.com.
2. Pair ProCal SNAP to the vehicle.
3. Recalibrate vehicle with ProCal SNAP
NOTE: The ProCal SNAP does not record the changes into
your vehicle’s history with FCA/Jeep. Any Warranty or Recall
that requires a re-programming of the modules may erase
the ProCal SNAP settings and require you to use the ProCal
SNAP to adjust your settings again.
