RaceChip XLR Throttle Controller with App for BMW X3 (G01) 2017+ - Pedal Box / Throttle Booster / Accelerator Pedal Tuner - Bluetooth Plug & Play Pedal Response Module for Petrol & Diesel

Transform the way your BMW X3 G01 responds to your right foot. This smart accelerator pedal controller is the must-have upgrade for anyone who wants crisp, immediate throttle feel on the 2017-onwards X3. With smartphone control via Bluetooth, seven finely stepped driving profiles and true plug-in installation, it delivers instant, confidence-inspiring response for everyday driving, overtakes and spirited B-road runs.

Unlike a remap, this pedal response module doesn’t alter engine output. Instead, it optimises the signal from the drive-by-wire accelerator, removing that doughy delay you feel when you set off, pull out of junctions or roll on mid-corner. The result is sharper pickup, more engaging acceleration and a car that feels alive under your foot.

• App-controlled throttle response controller with seamless Bluetooth connectivity
• Seven adjustable sensitivity levels from relaxed to aggressive for on-the-fly tailoring
• Instant improvement to pedal feel and reduced perceived lag for quicker getaway and cleaner overtakes
• Stock-feel mode available at any time when you want factory behaviour
• No ECU programming, no increase to peak horsepower, fully reversible
• Fast, tidy, plug-in fitment with OEM-style connectors for a clean install

Optimised for: BMW X3 (G01) 2017 onwards. Ideal for petrol and diesel variants across the range where sharper accelerator response is desired.

Our team at MJ Modifications has run this unit on our own builds and countless customer vehicles with superb feedback. Drivers report a more responsive, connected feel in traffic and on the open road, with the flexibility to dial in the exact sensitivity they prefer via the app. It’s one of the highest-impact, best-value drivability upgrades you can make to an X3.
