6.7L Cummins (CMF)

This collection is made for 2019–2021 Ram 2500 and 3500 pickups with the 6.7L Cummins CMF engine. These trucks require updated connections, which is why we offer the Dodge Smart Access Cable for 2018+ models. Pair that with the EZ Lynk Auto Agent 3 or EFI Live AutoCal V3 to load tune files designed to delete DPF, EGR and DEF systems where legal. The SOTF Switch & Cable Kit makes changing power levels quick and easy during operation.

For drivers running Mini Maxx devices, both V1 and V2 DPF Delete Tuners are supported, along with the OBD2 to HDMI Adapter for live data. Every tuner and cable here fits within the 2006–2021 range, but each part is confirmed to work with CMF‑coded ECMs found in 2019–2021 models. These products are intended for off-road or closed-course use only.
