Performance tune for F8x M3 / M4 (2015+)


F8x M3/M4 TUNE

This is our tried and tested tune for an F8x M3/M4. These tunes were designed on a Dynojet dyno and tested in the real world! A Windows computer is required to utilize the RK-Tunes flash software. For an additional charge, we can include a Windows operating tablet and OBD2 to USB flash cable that can be used in place of a Windows operating computer.

⦁ Increased target boost pressure
⦁ Top speed governor removed
⦁ Increased Valvetronic valve lift
⦁ Increased RPM rev limit (optional but not suggested)
⦁ VANOS cam timing adjustment
⦁ smoother throttle response
⦁ Ignition timing enhancements
⦁ Air/Fuel Ratio enhancements

⦁ Fuel - Selectable fuel octane rating (91, 93, E85 blend up to 100% E85 if your fuel system can handle it)
⦁ Rear O2 Sensor desensitization - If you are running aftermarket downpipes please make sure to type so in the modification box O2 Sensor delete.
⦁ Cold Start Delete - All F8x M3/M4s have a cold start calibration to heat up the catalytic converters. If you're unhappy with the way your M3 or M4 idles/runs/sounds while cold please type in into the modification box and we will disable the cold start in your tune. This is highly advised if you are running a cat less exhaust system as the cold start is often very loud.
⦁ Backfire/Burble. This makes your car backfire or burble when you lift off the gas. The aggressiveness can be adjusted depending on what you want. We suggest catless downpipes if you want an aggressive burble / backfire.

60 to 150 WHP
60 to 150 WTQ

For this tune you can mail in your DME for the initial flash or you can use the flash cable option if you have a windows computer/laptop for the initial flash. We supply instructions on where to download our software and how to use the flash cable. If you do not have a Windows based computer, laptop or tablet we can supply one for $100 more. Our Tablet option comes preloaded with software that allows for you to switch between tunes. Each map change takes under 2 minutes. This will allow you to turn on and off burble, cold start, switch between stock and your performance tune, and/or any other options we offer for your DME. Please see our DME Tuning info tab at the top of this page for more information. In the modification box, please specify all current vehicle modifications and desired options.
