3.0L EcoDiesel PCM Upgrade Service

3.0L EcoDiesel PCM Upgrade Service | Ram 1500 (2020–2022) & 2020 Jeep Wrangler/Gladiator

This 3.0L EcoDiesel PCM Upgrade Service is a required send-in modification for select 2020–2022 Ram 1500 EcoDiesel and 2020 Jeep 3.0L EcoDiesel vehicles before custom tuning can be performed.

Beginning with later-model EcoDiesel platforms, the factory PCM contains enhanced security protocols that prevent direct calibration access. This service modifies the controller to allow supported tuning platforms to communicate properly with the vehicle.

This is a send-in service only. The PCM must be removed from the vehicle and shipped to us for modification.
