The BMS Pedal Tuner is a BMW Performance Chip with a pre-programmed internal chip that intercepts the stock signals from your BMW's electronic control unit (ECU) and changes them to achieve better performance by adjusting the air-fuel ratio and spark timing. Made specifically for the BMW inline six-cylinder motors. The PBX also has an adjustable throttle feature that can be combined with the Performance chip feature by selecting a setting or "map". The BMS Pedal Tuner contains both a performance chip which gives you an extra 8-10 Horsepower at the wheels and an adjustable throttle boost feature that makes the gas pedal send a boosted throttle signal in increments of 30%, 60%, and 100% over the stock BMW signal. Depending on what setting/ "map" you select you can create a perfect blend of throttle response. The BMS Pedal Tuner will make your vehicle more responsive, spirited and fun to drive. It will make your vehicle faster by increasing the horsepower and torque. It works well with other modifications like intakes and exhausts, but can also be used alone. It will remove the "dead space" when you push on the non-responsive stock BMW accelerator. It changes the way the car drives and feels. You can turn it on and off from the comfort of your driver's seat to feel the difference. The BMS Pedal Tuner is a clear choice. Features: Throttle Re-mapping for Better Response / Reaction Removes "dead area" delay in gas pedal 7 Different Maps / Settings for more enjoyable driving Can be set and turned on and off from inside the car Invisible to dealers equipment Made in USA

Performance software is a must-have upgrade on your BMW and you won't find an easier and better software solution than the Shark Injector. Developed by BMW tuning expert Jim Conforti, this device plugs into the car's diagnostic port and flashes new performance files into your car's engine computer (ECU). There's no removal of the ECU and shipping, no cables, no laptop required - only a battery charger! Installation takes just a few minutes and your engine will perform like never before!

The M54 performance software was developed on the dyno to create maximum power and torque using premium 91+ octane fuel while maintaining BMW reliability and smoothness. The software makes changes to the ECU's maps and algorithms for fuel injection, ignition timing, VANOS and camshaft movement, and transitional fueling. A lot of tuning has been done at the low RPM ranges to improve response. We modify the maps for part throttle and full throttle so you get better response and more torque at all RPM. We also raise the rev limit to 7,000 and remove the top speed limiter. By fine tuning these maps we've been able to improve the M54/M56 engine beyond what BMW did by making more power and torque and a smoother-running engine.

The Shark Injector plugs into the diagnostic port inside the X3 cabin. With the battery charger supplying power, press the Upgrade button and within minutes the ECU is reflashed with the new performance tune. No other software product on the market comes close to how easy it is to install. You can use the Restore button to re-install the stock BMW software at any time. Detailed instructions are included. Other tuners require you to remove the ECU and ship it to them or use a laptop to read and write a new file. The Shark Injector is ready to install right out of the box! A planned future upgrade will allow you to use the USB port to load different performance files.
