WHAT IS RACEBOX
RaceBox is the most modern and precise way to measure the performance stats of your vehicle. Measuring 0-100km/h acceleration, 1/4 mile times or laps around your favorite race circuit has never been easier. Join the RaceBox family today and all this will be just a press of a button away from you.
RaceBox uses the latest generation GPS. This provides an outstanding accuracy and positioning - as low as 25cm running on the internal antenna. Combined with the purpose-built hardware, RaceBox has mind-blowing performance - over 99.5% measurement accuracy to a hundred of a second, compared to official lap/drag timing equipment.

It also provides you with the easiest and most intuitive user interface as well as the most ergonomic shape and form-factor. All of this in a price range significantly lower than anything else in this area.

In the box you get the device itself, windshield suction cup mount, charging cable and an external GPS antenna for even better precision.

Product Description
AUTO-BLiP automatically blips (opens) the throttle when downshifting gears on a car equipped with a manual transmission and an electronic accelerator pedal system. This allows the driver to focus 100% on braking while simultaneously downshifting gears.
Reduces mechanical wear and tear on manual transmissions and improves vehicle stability when downshifting gears.
Simply put, better brake control combined with optimum engine drive equals faster lap times.
AUTO-BLiP Intelligent Downshift Device features:
- Simple connection to your vehicle’s existing sensors. The AUTO-BLiP connects directly to your vehicles throttle pedal position sensor (TPPS), brake pedal switch, and clutch safety interlock switch.
- On-the-fly tuning capability made easy via the two face plate mounted dials. By simply turning the dial labeled “DURATION”, the user is able to set the desirable RPM blip level. The “DELAY” dial allows for the addition of a constant time delay from the time a downshift event is sensed to when the unit generates the throttle blip event.
- Simple one-time calibration routine for easy interface to your vehicle’s OEM sensors. Once AUTO-BLiP has been properly installed to your vehicle, a six step calibration routine allows it to learn your vehicle’s throttle, brake, and clutch configuration.
- Four LEDs display the unit’s functional status. The AUTO-BLiP provides the user with a simple and easy to view status of the brake pedal, clutch pedal, and blip events.
- On/Off button mode. By simply toggling the On/Off face plate mounted button, the unit will toggle between the active blip mode and a bypass low power mode.
- Will not interfere with your vehicles on-board diagnostics. The AUTO-BLiP has been designed to work with your vehicle’s OEM electronics without causing any engine fault codes
- Auto power down mode. The AUTO-BLiP will automatically go into bypass low power mode after 6 hours inactivity.
