GPR Rotary


MoTeC’s GPR Rotary Package is a versatile and adaptable platform for the operation of rotary engines with up to four rotors.

This single product can be configured over a huge range of rotary engine configurations, from controlling a simple, naturally aspirated 13B to a multi-throttle, boosted quad rotor with three injectors per rotor.

This Package also includes vehicle integration for modern rotaries such as the Mazda RX7 and RX8.

Included are many ancillary features commonly found on race cars, such as anti-lag, driver switches (e.g. pit switch, launch enable, boost trim), gearbox control, knock control, intercooler sprays, launch control, traction control, gearbox differential and coolant pumps. Also accommodated are many systems found on modified road vehicles, such as air conditioning.


The product fully integrates with other MoTeC products, and provides pre-defined CAN messaging for all current  MoTeC Dash Loggers, E888, V2 , GPS, ADR , BR2 , PDM and SLM. A Vector database (.dbc) file is available on request.

The Package is available for use with MoTeC's M130, M150, M170, M190 ECUs.
