Epic Motorsports - ECU Performance Software - BMW E36 M3 (S52)

EPIC Motorsports was founded in 2004 by Randy Mueller with the concept of maintaining a few key elements inherent to motorsports success. Winning six National Championships and playing an instrumental role assisting others obtain similar results proves that EPIC’s success is not mere luck. Knowledge, precision, commitment, and teamwork drive EPIC’s success.

The Epic Motorsports Engine Calibration Interface (ECI) was developed as a means to give BMW enthusiasts more control over their BMW’s engine performance. With this specially designed ECI tool, you have the ability to install the full range of Epic performance software calibrations and/or return the vehicle to its factory calibration settings. The ECI also doubles as an OBD II scanner capable of reading and clearing DTCs (Diagnostic Trouble Codes). Your unique ECI tool plugs into your vehicle’s OBD II port and into the USB port of your PC. With the user-friendly Epic Engine Calibration Interface PC software, you can read the existing factory (or aftermarket) programming from your vehicle’s ECU.

After purchase of an Epic tune you email your current calibration data to Epic for an upgrade to one of the various Epic Motorsports calibrations optimized for the specific vehicle. You will then load your modified calibration file into the ECU using the same ECI tool.

Through custom ECU tuning we are able to provide more usable horsepower and torque outputs by modifying BMW’s cam timing (VANOS), fuel maps, and ignition maps. The rev limiter can be set between 7000-7400 RPMs depending on camshaft choice. Optional custom software for larger airflow meters, headers, larger cam shafts and bigger injectors is available.

A build sheet will be emailed to you after purchase to get your vehicle info/build prior to tuning to confirm specific options and tune parameters.

Epic Motorsports Tune Levels

• Street: For daily drivers or vehicles used on a public highway. Street tunes do not affect emissions calibration tables. VANOS, fueling and timing changes provide considerable gains in full and part throttle compared to stock calibration. Consists of raised rev limiter and removal of speed limiter.
  
• Race: Reserved for those with HFM, injector, camshafts or aftermarket headers/race exhaust. Race tunes are not intended for use on public road and are restricted to a racetrack only.
  

• Raised Rev limiter
• Remove Speed Limiter
• Changes in VANOS for optimum driveability and power delivery
• Part throttle ignition and full throttle ignition optimization
• Part fueling/full throttle fueling optimization
  
• Intake Manifold: Stock or M50 Intake
• Aftermarket Cams (Schrick or Sunbelt) & larger injectors
• Larger HFM, headers or Aftermarket exhaust systems
  
• Disable Misfire Detection
• Delete EWS
  

You now have complete control of the calibration that is in your car, switchable from modified or stock at will. For those concerned with warranty, the factory calibration can be reinstalled before a trip to the dealer, leaving absolutely no trace of “tuning”. After service/warranty work, you can reinstall your Epic Motorsports calibration. The Epic ECI is only available when purchasing an Epic calibration or for previous Epic calibration purchasers. ECI loads coded Epic files only. This tool provides an easy method to load and switch calibrations; it does not give you the ability to view and modify your own files. Epic ECI marries to the ECU of your car on installation, after which it cannot be used on another car.
