## Long description

JETTER MRS Electronic Throttle Corrector with Control Key Fob MERCEDES. Compatible with multiple Mercedes models and years listed in the product information. The JETTER JET-MRS is a separate plug-in module that connects to the accelerator pedal position sensor connector without modifying vehicle parts. It contains a microprocessor that converts pedal position sensor signals and sends the modified signal to the engine management controller to change throttle response and reduce throttle opening lag.
Advantages
JETTER creates a more direct link between accelerator pedal position and throttle valve movement, reducing delay in throttle opening to provide faster torque and power delivery. The device is maintenance-free, transparent to the engine diagnostic system, and does not alter the engine control algorithms responsible for fuel injection, ignition, ABS, traction control or other safety systems. Installation is straightforward, though professional installation is recommended to avoid damage to wiring harness connectors.
Suitable for
Drivers seeking improved throttle response and quicker acceleration
Owners of compatible Mercedes models from the listed years
Situations requiring more immediate engine response (e.g., overtaking, merging)

How to use
Install the JETTER module by connecting it to the accelerator pedal position sensor connector according to the supplied instructions or have it fitted by a specialist to avoid damaging vehicle wiring harness connectors. After connection the module’s microprocessor will intercept and convert pedal sensor signals and forward them to the engine control unit. Use the included control key fob to operate or adjust the unit as designed. The device operates autonomously and requires no routine maintenance.
Usage recommendations
Depending on driving style, fuel consumption may increase or decrease; typical variance can be up to ±0.4 liters per 100 km. For maximum effect, disabling traction-control or slip prevention systems with the vehicle’s standard controls may be advisable in certain driving conditions. Because of connector sensitivity, professional installation at a service station is recommended.
