No other tuner has more experience tuning the S65 for the racetrack than Epic Motorsports. Their Stage 1 and Stage 2 software tunes deliver more power and torque than any other tuning program we have seen to date and Epic software has powered every BimmerWorld M3 race and project car from our shop in Virginia to the top of Pikes Peak. This is the Epic Stage 1 Street software for stock cars or with simple bolt-on upgrades like a cold-air intake or cat-back exhaust (stock cats still in the car). A Race tune is also available for race/track cars that eliminated the cats.
  • Tuned by the most experienced S65 builder in the US
  • +17hp / +19ft-lbs
  • 8,600 RPM rev limit
  • Fuel & timing matched to premium fuel
  • Raised top speed limiter
  • Faster throttle response
Stage 1 software is a greater refinement of the stock software, revising the fuel, VANOS, and timing tables to better match premium fuel (91+ octane). Factory torque limiters are also revised to allow greater torque output. The stock software is actually quite good but leaves some room for improvement as long as you always use premium fuel. Unlike other tunes, our gains are not made with changes to the factory anti-knock safeguards which protect your engine. Further refinements are made to the throttle maps for smoother and faster throttle opening, the top speed limiter is raised/eliminated, and the rev limit is raised to 8,600.

Epic software exceeds other tunes that are based on the factory 240E version. Epic reverse-engineered the stock software to go beyond the 240E update. There is no need, or benefit, to having the 240E update pre-installed before the Epic tune. This saves time and greatly simplifies the install process. The tuned file you receive back from Epic will already include the enhancements.

Software is installed with the included Epic Motorsports Electronic Calibration Interface (ECI) 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.
