E39 M5 Tune

This is our tried and tested tune for an E39 M5. These tunes were designed on a Dynojet dyno and tested in the real world! All tune packages come with an OBD to USB cable and software to read and write your DME/ECU. A Windows computer is required to utilize the RK-Tunes flash software. For an additional $100, we can include a Windows operating tablet that can be used in place of a Windows operating computer.

⦁ SAP (Secondary Air Pump) Delete - If you have deleted your Secondary Air Pump, please select this option and we will remove the coding from the DME/ECU to avoid a CEL.
⦁ Cold Start Delete - All E39 M5's have a cold start calibration to heat up the catalytic converters. If you're unhappy with the way your M5 idles/runs while cold, select this option and we will adjust the cold start in your tune. Highly advised if you are running a catless exhaust system.
