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

Dodge / Jeep / Ram 3.0L EcoDiesel PCM Upgrade Modification Service

SKU: SM-001

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. 

NOTE: PCMs with broken “LOCKING” tabs or connectors WILL NOT be accepted for upgrades.

• 2020–2022 Ram 1500 3.0L EcoDiesel
• 2020 Jeep Wrangler 3.0L EcoDiesel
• 2020 Jeep Gladiator 3.0L EcoDiesel

(Verify application before purchase.)

Important: Smart Access Cable Required

These vehicles will also require the Smart Access Cable (SKU: H-002-01) for proper communication with supported tuning devices after the PCM has been upgraded.

The Smart Access Cable is sold separately.
