Epic Motorsports software tuning for the E46 M3 consistently provides more gains than any other tune on the market (old or revised). 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.

Performance - an "off-the-shelf" tune that produces superior power and torque gains and can be custom-tailored for your preferences. Every file is done based on your stock tune (not a canned file) so you can add options such as Sport Mode Memory, octane preference, custom rev limits, DSC button control, and top speed limiter all in one file. This is a street tune and assumes the factory catalytic converters, EGT, and O2 sensors are in place. Even though the gains are the same between Performance and Race, reliability and durability is not reduced for normal street use.

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 by either sending in your ECU or with the Electronic Calibration Interface (ECI), which is discounted but sold separately. Contact us before sending us your ECU. Turn around time is typically 24-48 hours. All Alpha-N tuning must be done with the ECI.

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.
