    • Calibration is locked. Customers cannot view or change any of the tuning parameters.
  • Customers can use Dynojet PV-3 or PV-4 devices to flash our provided DJT calibration file:
  • DJT calibration file is software level 942. This is the latest version H-D has released for 2017-2020 touring models. The stock calibration will be overwritten when new calibration for the MK136 is downloaded/installed. This file covers both twin cooled and oil cooled engines.
