Our innovative throttle tuning system lets tune your engine’s reactions to your taste – choose from 7 separate stages.

• 2 Sport (S, S+) and 2 Race stages (R, R+) sharpen throttle response, speeding up the engine’s reaction times, making it as reactive as even a sportscar’s.
• 2 Eco stages (E, E+) slow down the engine’s reaction to movements of the throttle. In heavy city traffic and on long journeys, this can help you reduce fuel consumption.
• You can select N if don’t want or need to use XLR, and your car is back to stock tune.

Simple and easy to understand – installed in a few steps:

• Unplug the wire from the throttle at the connector.
• Connect the Brainbox to the connector/adaptor.
• Mount the Brainbox on a smooth surface in the footwell.
• To control XLR: connect the Controller with the Brainbox, or set up the RaceChip app.
• Done! Now – go drive and enjoy!

You can experience totally new driving sensations if you combine RaceChip XLR with one of our chip tuning modules. The extra power and torque that chip tuning brings is perfectly complemented by the immediate throttle response made possible by throttle tuning. Together, they push back the limits of driving enjoyment.

RaceChip is the first company to offer throttle tuning together with app control. The combination gives you the easiest ever way of controlling your vehicle’s throttle response. RaceChip XLR connects directly with the RaceChip app on your smartphone via Bluetooth.

If you already have a RaceChip chip tuning module in your car, XLR is the perfect add-on, and using them together is even easier – you can control both modules from the driver’s smartphone using the same app.

We developed RaceChip XLR to increase responsiveness on the road. Your engine’s performance isn’t affected by RaceChip XLR, but you can access it more immediately and directly. Experience significantly sharper responses for yourself – no waiting for the message to get through or frustrating hesitations.
