Active Autowerke's engineers have spent countless years fine tuning the E46 BMW M3 software. With on-going revisions and updates being made continuously both on our Race and Forced Induction programs, they have made possible the refinements needed for a true hi-performance street tune. Within specific ares of the MSS54 DME, the algorithms have been altered to achieve more usable horsepower and torque by re-working features such as the engine VANOS (dual variable valve timing), fuel and ignition maps and torque dampening. Other noticeable results are better warm starts, with a crisper and a more responsive throttle. So whether you enjoy you car as a daily driver or enjoy the weekend track outings our BMW M3 tune software will be able to accommodate your needs.
Through careful, detailed remapping to the entire DME we have been able to increase your S54's output by 14 HP and 11 ft lbs of torque on a stock BMW E46 M3 with factory settings for a normal street car. We also have different upgrades available for off-road use like sport button modification, SMG shift light feature to your 6 speed model, 02 Simulation, etc. The software is designed to operate with gasoline that has an average octane rating with full emissions to create a clean burning combustion with good AFR’s all within factory specifications. Paired with our BMW M3 Sport Header the gains are even more dramatic!
