A powerful piece of hardware

The Brainbox – the nerve centre

The Brainbox is the nerve centre of XLR and not only controls the processes needed to optimise throttle response, it also communicates via Bluetooth with the RaceChip app, meaning you can control XLR direct from your smartphone.

The Brainbox’s compact size (ca. 70 x 80 mm) allows it to be fitted easily in the footwell of your vehicle. As it is so flat, it does not restrict the driver’s legroom at all. It can be fixed almost anywhere in the footwell, for example in existing slots or vents.

Easy to control

Control your car’s throttle response using our app

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.

7 stages with different driving characteristics

Driving dynamics as you want

The XLR Controller allows you to choose between 7 stages: Eco+, Eco, Neutral, Sport, Sport+, Race and Race+. Each stage sharpens your car’s throttle response a little more, until in Race+ it’s like a thoroughbred sports car.

You can mount the Controller anywhere in the car so that it’s in the right place for how you want to use it. The size and design mean it fits right in with the rest of the interior and the other control elements.

How RaceChip XLR works

The RaceChip XLR is installed between the throttle pedal sensor and the engine control unit. Depending on the XLR’s tuning stage, it either amplifes or reduces the signals sent by the throttle pedal sensor in accordance with characteristics defined by our engineers. The effect is that you can choose how your car reacts to your throttle inputs.

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.

RaceChip XLR is available for any car equipped with an electronic throttle, regardless of whether the engine is naturally aspirated, turbocharged, supercharged, electric or hybrid.

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!

Made for each other:
Chip Tuning and Throttle Tuning by RaceChip

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.
