RaceChip XLR Bluetooth Throttle Controller with App for BMW Z4 E89 (2009–2016) – Pedal Box / Accelerator Pedal Tuner / Gas Pedal Booster – Plug & Play Throttle Response Controller, Lag Reduction

Bluetooth Throttle Controller for BMW Z4 E89 2009 onwards

Unlock razor sharp accelerator response in your BMW roadster with this app-controlled throttle controller. Designed for the E89 platform, it delivers a faster, crisper pedal feel and reduces the dull delay you get with drive-by-wire systems. No engine tuning, no power increase claims, just immediate, more engaging response every time you touch the pedal.

Control it from your smartphone via Bluetooth and tailor your car’s behaviour to your preference with 7 adjustable levels. Whether you want smooth, relaxed tip-in for town or ultra-responsive input for spirited B-road runs, you can fine tune pedal sensitivity in seconds.

This unit works by optimising the signal between the accelerator pedal and the ECU, so your engine’s output remains unchanged while responsiveness is transformed. It is a true plug-and-play upgrade with straightforward installation and no specialist tools required.

Key benefits

• Bluetooth control through a simple smartphone app
• Seven distinct stages to dial in pedal sensitivity to your taste
• Sharper throttle feel and reduced pedal lag for a more connected drive
• No change to engine mapping or power output
