Turner Motorsport S85 Performance Software - (NO LONGER AVAILABLE)

Building on their success in tuning BMWs for the race track - Turner Motorsport has developed high output street software for the already-high-performance E60 M5 and E63/4 M6. 

BMW tuned the S85 V10 to run on "regular" 87 octane fuel to accommodate the number of passive drivers that would simply put regular gasoline into their tanks. With this in mind, that provides room to increase engine performance by flashing your ECU with software designed to optimize performance for higher octane fuel. 

Features of this software include:

• Tuning for 91 or 93 octane fuel (we recommend 93 octane if it's available in your area!)
• Expect gains of 25 horsepower and 20 ft-lbs of torque (with 93 octane, slightly less with 91)
• Rev limits of 8,250 (stock) or 8,500 (raised!)
• Part throttle and wide open fuel and timing maps are optimized 
• Revised torque settings and knock control
• Smoother, faster pedal response
• Eliminated top speed limiter
• Tuned engine performance is even more pronounced on modified vehicles

Turner Motorsport took years of winning race experience and developed their S85 tunes utilizing their in-house Dynapack chassis dyno, finalizing software with real-world road testing. This is software you'll enjoy day-to-day and that will continue to put a smile on your face.

Loading Turner's S85 Performance software is a simple process, done through the OBDII port in your garage or driveway. We ship you the OBD tool, USB cable, and performance software files along with simple instructions on how to load the software from your Windows XP/Vista/7/8/10 laptop to the OBD tool and upload to your ECU. The whole process takes less than an hour. 

 *Dyno HP and Torque figures are not guaranteed to test identically to posted numbers on your vehicle. Metrics we present were achieved in our own testing environment, however, a variety of factors may affect results of the tune on your vehicle*
