Bimmian SPBAAXA2Y Sprint Booster Throttle Remapper- For BMW E53 X5 E70 X5 E83 X3- All M Vehicles or Non-M with Automatic Transmission- Version 2 With Switchable Mapping Profiles

Sprint Booster is a fully-reversible, quick and easy to install modification for your vehicle that will greatly improve the way your vehicle feels to the driver.All modern BMW vehicles employ DRIVE BY WIRE technology meaning that the pedal when depressed, sends an electrical signal to your ECU that controls the throttle. This differs from older vehicles where the pedal is attached by cable directly to the throttle.The problem with this New technology, is that the pedal will modify the input from your foot before forwarding the signal to the ECU. This signal is modified to add some delay from the time of input to throttle position change, it remaps the pedal depression to throttle opening to be non-linear (explained below) and it limits the throttle opening potential. These things are done to make the ride of the car smoother and less aggressive. This is done so that car manufacturers can get a higher approval rating from the majority of non performance-oriented consumers.Consumers interested in vehicle performance, however, want to have direct control over vehicle acceleration. By installing the sprint booster throttle remapper, the CPU chip inside the sprint booster does these three things:Eliminating the lag between pedal input and throttle response, making for more immediate vehicle response when you press on the pedal.Removes the restriction on throttle opening, now the throttle can open up to 33% wider, allowing for more power to be generated at lower RPM ranges. It does not increase overall horsepower, just where this horsepower is made.Linearly maps the pedal depression to throttle opening. Press the pedal down 20% and the throttle will open 20%. Press the pedal down 50% and the throttle will open 50%. Without sprint booster, when you depress the pedal 20% the throttle may open 10%, when you press down 40% it may open 25% and when you press down 100% it may open 75%. This is not linear and is not a natural way of driving.These three benefits combine to provide a much more enjoyable driving experience. The vehicle feels much more responsive, powerful and fun to drive.For those occasions where you want to reduce the benefit of the sprint booster (ie. lending car to friends / family) the included switch may be used to reduce the enhancement provided by the sprint booster, or switch it off completely, back to stock.The Sprint Booster is designed, manufactured and patented in Greece, and is TUV safety-approved.Installation is simple:Loosen the accelerator pedal module from the floorboard.Unplug the harness from the accelerator module.Plug in the SprintBooster inline with the harness and accelerator module.Re-install the accelerator module.Optionally, plug the switch into the Sprint Booster, run wire along or through dash and use included double sided tape to mount switch.For BMW E53 X5 E70 X5 E83 X3-All M Vehicles or Non-M with Automatic Transmission.Version 2 With Switchable Mapping Profiles.
