This PCM upgrade service is required to tune 2015+ Dodge/Chrysler/Jeep/RAM vehicles (all FCA models, except the 2015+ Dodge Viper and 2014 to 2019 Jeep/Dodge/Ram vehicles with the EDC17C79 PCM). 2018+ models also require an HP Tuners Dodge 2018+Smart Access Cable to be able to tune cars via OBD port.






      • Please ensure you are sending in ONLY a PCM. No brackets, rubber isolators, or other pieces should be included, these components may not be returned with your upgraded PCM.
      • After the PCM arrives at HPT, an One of our  engineers will upgrade the PCM and enable your HP Tuners software so that the PCM can then be read, licensed, edited, and flashed with HP Tuners software! This is a one-time upgrade that will not affect other operations of the PCM. The factory tools will still work for service. And HP Tuners will then work for tuning!
      • While there is no hardware change, the back cover of the PCM does need to be removed.
    • Important Notes:

      • Please note this service is required to tune your 2015+ Dodge/Chrysler/Jeep/RAM (all FCA models, except the 2015+ Dodge Viper and 2014 to 2019 Jeep/Dodge/Ram vehicles with the EDC17C79 PCM). In addition to this service, all 2018+ models require an HP Tuners Dodge 2018+ Smart Access Cable.
      • EDC17C79 PCMs installed in 2014 to 2019 Jeep/Dodge/Ram vehicles do not need to be upgraded. The EDC17C79 PCM will update upon the first read of the ECM which will allow read/write abilities.
      • As of 12/21/2015, ALL non-original 2015+ Dodge/Chrysler/Jeep/RAM PCMs that are sent in for upgrade must have a stock read performed before it is shipped to us. This read must be uploaded before adding the Upgrade service to the cart.
      • If you are sending us a spare PCM, please make sure to send a read from the stock PCM. While we can upgrade it as a blank PCM without a read, you would have to flash the correct OS/VIN onto the PCM as well as most likely do a throttle re-learn and/or SKIM re-learn. If you can supply a stock read, we can flash the PCM here. The stock read must be done as a GPEC2A, 2015+ Dodge or a GPEC2, 2015+ Dodge (depending on which PCM the vehicle is equipped with. Please see the Dodge PCM Identification Thread if you are unsure which PCM you have). If you do not have access to perform the read, please download the latest update from your customer page and try again.
      • Once ordered, you can send either an original PCM or a spare. The spare has to be a compatible PCM.
