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.
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.
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.
