## Summary description

Electronic Throttle Corrector JETTER electronic MRS II is a control key fob designed for Mercedes vehicles. It serves as a remote for adjusting the throttle correction unit (MRS II), enabling on-the-fly tuning of throttle response and performance settings. Suitable for drivers seeking convenient, handheld control of throttle calibration without manual access to the control module. Ideal for use in workshop installs and everyday driving adjustments.

## Long description

JETTER MRS II Electronic Throttle Corrector with Control Key Fob for Mercedes vehicles. The module connects to the accelerator pedal position sensor connector without modifying car parts and contains a microprocessor that converts pedal position signals and transmits them to the engine management controller. JETTER modifies the relationship between pedal position and throttle valve to remove opening delay, supplying the working mixture earlier to increase torque and power response and improve acceleration dynamics while maintaining immediate throttle closure when the pedal is released. The device is maintenance-free and is designed to be electrically transparent to the engine diagnostic system; it does not change algorithms for fuel supply, ignition, ABS, TCS and other vehicle control systems. Fuel consumption may increase or decrease depending on driving style (typical change up to ±0.4 l/100 km). Installation is straightforward, but due to connector and harness design it is recommended to have the device installed at a specialized service station. More information: Jetterauto.ru

How to use
Connect the JETTER MRS II to the accelerator pedal position sensor connector following the vehicle-specific wiring layout. After connection, use the included control key fob to select the desired throttle correction setting while monitoring vehicle behaviour. The unit immediately adjusts signal conversion so the throttle valve responds with reduced lag; normal pedal release behavior is preserved. If unsure about connector access or wiring, have the device installed by a professional service technician to avoid damage to the harness.
Usage recommendations
For safest operation, verify compatibility with your specific Mercedes model and year from the compatibility list, and consider disabling traction-control systems using the standard vehicle controls when testing maximum response. If you are not experienced with vehicle electrical systems, request installation at a specialized service station.
