Many purchase the CSL for this very reason. We can bring this very feature to the standard E46 M3 owner. The E46 M3 CSL is widely regarded as making one of the best noises of any sports car. Stage 2 - BMW E46 M3 CSL style Carbon Airbox | AlphaN SoftwareĮ46 M3 3.2, performance gain approx. Quicker response resulting in improved initial acceleration Significantly more power at higher rpm's. Enhanced throttle response and drivability Rear Lambda Sensor delete for M3's without CAT's or high flow CAT's which trigger the engine managment We can also build into the software the following: A standard car will accelerate well upto 5500rpm but beyond that the power begins to fall. Once upgraded the power continues to climb leading to a far more linear power delivery. The Evolve software makes a significant change to how the E46 M3 drives and accelerates. In terms of 'peak' power, between 20hp is available above 5000rpm. Low end torque and top end power are the main areas which improve the most and it is these very areas which need improvement. Typically we saw improvments in throttle response and nothing more.īy recalibrating ignitiong timing, VANOS timing, torque limiters and fuelling more power/torque is available at both partial and full load. This is what the industry has seen over the years with no gain in power neither on the road or the dyno. Conventional methods of advancing the ignition timing under full load has little effect. The E46 M3 S54 engine responds well to the right type of ECU software. Many claims to 15-30hp+ have been made over the years but nothing ever materialised. V-MAX releaseĢ009 saw further developed and something completely new for the S54 engine to allow real power gains. Note: The average power of an E46 M3 is 325-330hp standardĮ46 M3 3.2, performance gain approx. 20hp incl. If you would like to discuss something different to what you see below please contact us.

We have given a suggested upgrade path below but there are many other combinations available. We have developed a full range of upgrades for the S54 engine.
