This is for existing customers who already have a BPM Sport Tune for the E9x M3.
Created with extensive research and testing of the ECU the upgrade transforms power and drivability. Developed with 100's of hours of dyno testing, datalogging and endurance testing we deliver more torque on a stock vehicle while retaining maximum safety margins.
Through careful remapping of the factory BMW DME tables, various elements such as ignition timing, fuel delivery, VANOS position and part throttles are reworked to create performance gains.
We also rework the torque calculations correctly to give consistent power. The latest version of our ECU flash has been thoroughly developed and gives an actual gain in performance rather than just a quoted figure. The result is a car that feels far sharper and pulls harder through the rev band.
• Easily program your vehicle with the performance software or flash back to stock - in less than 10 minutes!
• Read and clear fault codes and clear check engine lights with our easy to use software.
• Calibrated exclusively for this exhaust setup.
• Safe, reliable, tested extensively.
