TRM MS S54 Swap Tune


SKU: 030-20 Categories: , , , , ,


TRM’s MS S54 Swap Tune. The best performance software available for your S54 engine that has been swapped into another chassis. Removes all of the emissions systems that are no longer viable on your E30/E36/E46/etc track rat, as well as removing EWS, to allow the ECU to be used as a standalone. Only needs the basics wired to the chassis.

If you are looking for software for your E46 M3 and it is not a track car, we recommend the TRM S54 Performance tune.

Just like the TRM S54 Performance Tune, this optimizes the cam timing, fuel and spark maps, as well as smoothing the throttle map for better drivability and power delivery. (More on throttle mapping for those interested.)

ECU can be shipped to us for programming or can be flashed remotely.

TRM can also handle all of your wiring needs. Custom harnesses available for PNP installation into any chassis. We will need to know what chassis is to be used, as well as what pedal configuration (Z3 or E46) for the throttle.  Please contact us for with any questions or for any of your integration needs.

For CAM tunes, or just to get the most out of your car, we recommend a custom tune.
