BMW M3 E46 Track Car Gets Powered Up with a VR Tuned ECU Flash VRTuned.com October 23, 2014 Company News, Media & Events, Product Info We always love getting photos of our customer cars to share to the world. This particular customer from New Jersey has a BMW M3 E46 track car. We did one of our VR Tuned ECU Flashes to it to improve the cars throttle response, mid range power, and top end pull. The inline 6 cylinder M engine still has some power to gain with adjustments to the fuel mixtures and timing. In addition to altering the torque limiter and increasing the top speed limiter, the tune overall enhances the M3 past what a European spec E46 would do.
