2022 Trucks Must Be Verified

The 2022 model year includes different electrical architectures and ECM configurations. Some trucks use the supported E46 ECM, while refreshed trucks may use the unsupported E66 Global-B controller.

A larger, newer-style infotainment display can indicate a refreshed truck, but the screen alone should not be used as final confirmation.

Please provide your complete VIN before purchasing so Dyno Diesels can verify compatibility.

CCS LM2 Tuning Benefits

CCS custom tuning is written around your truck’s specific configuration rather than relying on a generic, one-size-fits-all calibration.

Depending on the selected tune and installed supporting modifications, potential benefits may include:

Increased horsepower and torque
Improved throttle response
Quicker acceleration
Smoother power delivery
Improved drivability
Calibration for supported exhaust and emissions-system modifications
Multiple power-level options
Revision support when required

Actual results depend on vehicle condition, installed parts, maintenance, fuel quality, elevation and selected tuning level. Fuel-economy improvements are not guaranteed.

Information Required After Purchase

Please provide the following information when ordering:

Complete 17-digit VIN

Failure to disclose previous tuning or vehicle modifications may delay delivery or require additional diagnostic work.

Important Flashing Requirements

Always connect a proper battery charger before programming the ECM. Low or unstable voltage can cause communication errors, interrupted flashes or ECM recovery issues.

During the flash:

Keep the battery charger connected
Keep the phone or tablet near the EZ LYNK Auto Agent
Keep the EZ LYNK app open
Do not open doors
Do not press the brake pedal
Do not unplug the Auto Agent
Do not interrupt the programming process
Follow every ignition-cycle instruction exactly

Device, connection, firmware or application problems must be directed to EZ LYNK technical support.
