Jeep Grand Cherokee Speed Limiter Removal / Raise Service

MoPower Calibrations offers professional Jeep Grand Cherokee speed limiter removal and speed limiter raise programming for the supported applications listed below. This is a mail-in PCM / ECU programming service that modifies the applicable factory-programmed vehicle-speed limiting parameters directly in the controller calibration.

No external speed-governor bypass box or permanent wiring modification is required for the calibration itself. The service is performed against the vehicle-specific controller strategy rather than through a generic add-on module.

Speed Limiter Removal

The factory calibration can contain an electronic maximum vehicle-speed threshold. MoPower's speed limiter removal service changes the applicable vehicle-speed limiting parameters where supported so the original factory maximum-speed threshold no longer imposes that calibration limit.

Customers may also describe this service as speed governor removal, governor delete, top-speed limiter removal or top-speed governor removal. The actual work is performed by editing the applicable calibration parameters in the PCM / ECU.

Raise the Factory Speed Limiter

Complete removal is not required. MoPower can instead raise the factory speed limiter to a requested maximum speed where supported. Select Raise Factory Speed Limiter and enter the requested maximum speed in MPH.

A requested electronic limit does not guarantee that the vehicle can safely or physically reach that speed. Vehicle condition, tires, gearing, aerodynamics, power, environment and other mechanical factors remain independent of the programmed threshold.

This Is a Speed Limiter Service — Not a Full Performance Tune

This product changes the applicable vehicle-speed limiter / speed-governor strategy. It does not by itself add horsepower or automatically change ignition timing, fueling, torque management, throttle response, transmission calibration, cooling fan settings, cylinder-deactivation strategy or other performance tables.

Speed Limiter vs. RPM / Rev Limiter

The vehicle-speed limiter and the engine RPM / rev limiter are separate calibration functions. This service does not automatically raise or remove the engine RPM limiter.

How the Mail-In Service Works

1. Select the correct model year and exact engine.
2. Choose Remove Factory Speed Limiter or Raise Factory Speed Limiter.
3. If choosing Raise, enter the requested maximum speed in MPH.
4. Enter the full 17-character VIN.
5. Complete the order and ship the PCM / ECU to MoPower Calibrations.
6. MoPower reads and programs the applicable controller calibration, then returns the controller for installation.

Important Application Notes

Only the exact year, vehicle and engine combinations in the application table are offered. Unlisted gasoline, diesel, hybrid, plug-in hybrid and battery-electric applications are not included.

Controller strategy and calibration support can vary within a model year or engine family. If the PCM has been replaced, previously tuned, modified, swapped, or is from an unusual fleet/export application, contact MoPower before ordering.

Products and calibrations intended for closed-course, competition, off-road, export or other lawful applications must be used in accordance with all applicable laws and regulations. Not for sale or use in California where prohibited.
