Key Features
DFM Deactivation: Eliminates engine cylinder deactivation for smoother throttle response, better exhaust tone, and consistent V8 performance.
Plug-and-Play Setup: No tools, wiring, or permanent changes—just connect to the ECM and start driving.
Safe and Reversible: The module makes no changes to factory programming and can be removed at any time to restore OEM behavior.
Designed for GM Refresh Models: Specifically calibrated for newer GM trucks and SUVs with updated electrical systems and ECU protocols.
Improved Driving Feel: Prevents the inconsistent shifting and engine lugging often caused by active cylinder management systems.
How it works
The RA007 DFM Module installs directly into your vehicle’s ECM, typically located under the dash. Once connected, it sends signals that prevent the ECU from activating the Dynamic Fuel Management system, keeping all cylinders active at all times. This enhances engine responsiveness, eliminates V4 mode hesitation, and delivers consistent V8 power. The device does not reprogram your ECU, and its operation is reversed simply by unplugging it. It draws minimal power and begins functioning as soon as the ignition is on.
FAQs
How do I know if my vehicle is a “GM Refresh” model?
Refresh models are typically 2022+ and include interior and software updates. Check your vehicle’s manual or VIN to confirm.
Is the module compatible with diesel engines or V6 models?
No, it's designed only for GM V8 gas engines with DFM—typically 5.3L and 6.2L engines.
