Just wrapped up doing a ECU Tune on this customers convertible E93 BMW M3. Like all our other VR Tuned ECU flashes this was done via OBDII and at the convenience of the customer. Plug in, read out the car, email it in, get a new file, load it back to the car. That simple. Wake up the V8 with more torque, top end power, and better throttle response!
