Engine control unit (ECU)

Good throttle response

The ECU is encased in a rubber pad to minimize vibrations to the ECU, connector and the cables. 

One of the key features is the new ECU for Rotax 125 Junior MAX and the new ECU for 125 MAX engines - also used for Rotax 125 Micro and Mini MAX engines.

The slightly altered ignition timing enables the use of a bigger main jet size resulting in good throttle response at low rpm whilst still offering a wide rpm range, through to the rev limiter set at 14,800 rpm.
