Range Technology RA007 DFM Module for GM Refresh V8 Trucks & SUVs — 5.3L/6.2L Plug-and-Play, Disables Auto Start/Stop

The Range Technology RA007 DFM Module disables Dynamic Fuel Management and Engine Auto Start/Stop so your 5.3L or 6.2L GM Refresh V8 runs on all cylinders consistently.

The RA007 is a plug-and-play inline module engineered for late-model GM Refresh trucks and SUVs (2021–2024 SUVs and 2022.5–2024 1500 trucks) equipped with the 5.3L or 6.2L V8 engines. It intercepts the ECU signals that enable cylinder deactivation and auto stop/start, restoring continuous V8 operation without permanent wiring changes. The unit is designed to be reversible, leaving the factory system intact for dealer diagnostics or warranty inspections when removed.

How does the RA007 improve everyday driving feel?

By preventing cylinder deactivation, the module keeps all cylinders firing, producing more consistent throttle response, smoother acceleration, and the traditional V8 exhaust note. Drivers notice fewer hesitations at takeoff and a more predictable power delivery under load.

• Eliminates torque dips from cylinders dropping out
• Stops auto start/stop interruptions at intersections
• Retains full V8 sound and throttle feedback

Will installing this module reduce long-term engine issues?

The RA007 is designed to prevent the recurring problems associated with frequent cylinder deactivation and restarts by keeping the valvetrain and lubrication more consistent. While not a guaranteed cure for every mechanical issue, it reduces the operational stress patterns that have been linked to excess oil consumption and lifter or valve train wear in some vehicles.

• Reduces repeated activation cycles that can stress components
• Helps maintain consistent oil distribution and combustion conditions
• Provides a preventative approach to known DFM-related concerns

How is the RA007 installed and removed for dealer service?

Installation is simple: the module plugs inline with the vehicle's ECM connectors—no cutting or splicing. It can be removed without trace, returning the vehicle to factory operation for dealer inspections or warranty work.

• Plug-and-play inline design requires basic hand tools
• No permanent modifications to factory wiring
• Restores to stock when disconnected for clean dealer service access

Does the module affect fuel economy or emissions systems?

The RA007 keeps the engine running on all cylinders at all times, which can slightly change fuel use compared with intermittent cylinder deactivation. It does not alter catalytic converters or emissions hardware; it only modifies the ECU control signals for DFM and start/stop functionality.

• Alters engine management behavior only—no hardware removal
• May modestly affect fuel consumption depending on driving style
• Designed to be reversible for regulatory or warranty checks

Who is this for: The Range Technology RA007 is aimed at owners of 2021–2024 GM Refresh SUVs and 2022.5–2024 GM 1500 trucks with the 5.3L or 6.2L V8 who want uninterrupted V8 performance, consistent throttle response, and to avoid the operational patterns linked to certain DFM issues. It's ideal for drivers who prioritize reliable long‑term operation, those who regularly tow or haul, and owners who prefer the classic V8 sound and feel. Note: follow local laws and manufacturer guidelines when modifying ECU behavior. This product contains materials that may pose health risks under California Proposition 65.

• Disables Dynamic Fuel Management (DFM) and Engine Auto Start/Stop systems
• Smart inline technology integrates seamlessly with the ECM
• Allows a true ‘Return to Stock’ status when removed with no trace for worry free dealer services
• All-time V8 mode means better power on demand, a more consistent driving experience, reduced engine and valvetrain wear, and improved long term engine reliability
• Enjoy that V8 rumble and avoid unpleasant exhaust notes and drone from running in cylinder deactivation mode
