***Due to hptuners being 8-10 months out (backorder on tcm's) we are no longer offering the actual module for sale until we can get stock, tuning is still available for them if you can get yours unlocked or through other means**

 

For off road use you will need at least the minimum:

  • ECM
  • MPVI2 with 8 credits
  • Can bus jumpers
  • EGR solution
  • DPF solution

 

The rest is optional.

 

DSP5 tunes are based off steering wheel controls. This is true switchable tuning where each tune setting has it's own sets of maps.

  • To change positions, simply hold down the cruise cancel button for a few seconds and push up (resume/increase speed) on the cruise to go up in tune levels, down to go down. The glow plug indicator light will blink the amount of times for the tune level you are in.
