BMW M3 (F80) / M4 (F82) ECU Flash

Mase Engineering

Our custom ECU Flash for the BMW M3(F80)/M4(F82) has been proven to make a substantial increase in horsepower and torque over stock. By recalibrating fuel/ignition/boost tables we were able to extract over 100 horsepower to the rear wheels and 516 lbft of torque. Drivability will be much improved with a better throttle response and a smoother delivery of power throughout the whole RPM band. We highly recommend this flash for anyone looking to bring out the full potential of their M car. 

-This flash requires a bench flash which means the ECU (located under the intake manifold) will have to be physically removed from the car and sent directly to us at our facility located here in North Florida where we will have it flashed and mailed back out in a timely manner.
