MoTeC’s M1 GP PWC Package contains specific features unique to PWC applications, it is a versatile and adaptable platform for the operation of port-injected engines in Personal Watercraft. GP PWC is based on the GP Marine Package.

This single product can be configured over a huge range of complexities, from controlling a simple engine to a multi-throttle, quad cam boosted engine with two injectors per cylinder and many other features. Configurable engine synchronisation modes accommodate most modern engine triggering systems.

Included are numerous ancillary features, such as boost limit, knock control and launch control. It also caters for many systems found on marine vessels that may be useful in a racing context.

This Package is available across MoTeC's range of M1 port injection ECUs (M130M, M150M, M170M and M190M). It seamlessly integrates with other MoTeC products and provides pre-defined CAN messaging for all current Display/Enclosed Loggers, Power Distribution Modules and other devices including E888, VCS, GPS, ADR, BR2 and SLM. Example wiring pinouts are provided for basic operation using M130M and M150M ECU variants.

The Package is available for use with MoTeC's M130M, M150M, M170M and M190M ECUs. A pinout example for the M130M and M150M follows.
