TRM MS45 Swap Tune



SKU: 030-45S Categories: , , , , ,


TRM’s MS45 Swap Tune. The best performance software available for your MS45.0/MS45.1 equipped 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.

Just like the TRM MS45 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 we can flash remotely with our TRM MS45 remote flashing software. A flashed ECU is also available if you select “buy an ecu”, though subject to availability. Email first if you would like an ECU provided to inquire about timeline for shipping.

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.
