S54 Swap tune (E46 M3 motor in a different chassis)

­­S54 Swap tune for an E46 M3 motor with a factory Mss54 / mss54HP dme.

This turns the factory E46 M3 Engine DME into a "Stand alone" DME. It will now control a S54 engine in any chassis.

This is our tried and tested tune for an E46 M3 motor ( S54) to run in a different chassis or for a full race car. No abs, No Can system, no emissions, etc. These tunes were designed on a Dynojet dyno and tested in the real world! We offer both MAF based and ALPHA-N tunes. Our ALPHA-N tune has an additional 15% increase in power over the MAF based tune. The ALPHA-N tune requires the MAF to be deleted, and the installation of a new Air Intake Temperature Sensor included in your purchase. Please select whether you would like a MAF or ALPHA-N. 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. Check FAQ section for windows device recommendation.
