Epic Motorsports software tuning for the Z4M S54 consistently provides more gains than any other tune on the market. No other tuner has as much experience building, tuning, and racing the S54 engine than Epic Motorsports and BimmerWorld. It's this depth of experience that allows Epic to extract more power and torque. S54 software is available in three stages - performance street, race, or Alpha-N.

Race - tuned specifically for cars that see full-time track duty and have cat-delete, headers, straight exhaust, and other mods. The tuning is done based on popular mods used in our own race cars as well as others we have built for customers. Typically the tuning is the same as our Performance tune but with track-specific changes such as EGT and O2 sensor thresholds and other changes for track duty. Race software is sold for off-road use only (see emissions info below).

Alpha-N - Alpha-N is a true custom-built file that requires dyno tuning to dial in your engine and get the most horsepower and torque. Click here for our other listing for Alpha-N info and ordering.

Our software is installed via a D-CAN cable (included) and your Windows laptop (compatible with XP, Win7, Win8, and Win10). The D-CAN cable is included at this price. Read and email your stock file and a tuned file will be returned to you. This is better than off-the-shelf tunes that never look at your original software.
