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.
Software is installed with the Electronic Calibration Interface (ECI), which is discounted but sold separately. The ECI is connected to the OBD port in your dash and a Windows laptop. There is nothing to modify or remove and you never have to worry about modifications to the wiring harness. The ECI tool will read and save a copy of your stock software, which is then e-mailed to us for modification. A new tuned version of your original file is returned to you. This is better than off-the-shelf software tunes that never look at your original software. You can continue to drive the car while your tuned file is being processed.Notice of Emissions Non-Compliance.
