Our ECU remapping for the BMW M3 increases power smoothly across the entire rev range. We've adjusted various maps, including those for the VANOS, torque limiter, fuel quantity, and ignition timing. We achieved a measurable power increase of 26 hp and 22 Nm in vehicles without pre-catalytic converters. The engine also responds even better to throttle inputs, resulting in an even more exhilarating driving experience.
 We can also make various additional adjustments to the software upon request so that your M3 works exactly the way you want it to.
