  • Rev limit can be altered for m/t application
  • Zero trouble codes for downstream O2, cat converters, EVAP system
  • Quicker a/t shifts
  • Modified a/t shift points vs speed and accelerator pedal position (that results, in particular, in quicker downshifts). Individually tuned in ECT Normal/Power/Snow modes

  • No speed limit, both in normal and Cruise mode
  • Fan engagement temperature can be lowered for engine conversion projects with small engine bay
