MOTEC’S DISTINCTIVE RANGE OF M1 ECU SOLUTIONS

• Targeted Solutions – We’ve done the configuration work for you, tailoring the ECU firmware to a specific vehicle or engine. In some cases this includes integration with vehicle control systems beyond the engine, for example, stability control, cruise control. Complete Plug-In kits are available for some applications, including any additional hardware and wiring looms as required. See targeted solutions for Vehicle, Bike, PWC or Snowmobiles
• GP (General Purpose) Solutions – MoTeC’s GP Solutions offer the flexibility to suit numerous port and direct injected gasoline engines. Comprising of:
  – GPA (Advanced)
  – GPR (Race)
  – GPRP (Race with Paddle shift)
  – GPRDI (Race with Direct Injection)
  – GPRPDI (Race with Paddle Shift and Direct Injection)
  These variants that can be configured to suit a wide range of applications.
• Development Solutions – Those who are skilled at coding can now develop fully customised control strategies at the firmware level, creating unique ECU functionality for themselves or other customers. Developers can build custom controls into an existing package, or create a new project from scratch. In either instance, the resulting firmware can be loaded into a single Development ECU or rolled out for customers around the world to purchase.
• Ruggedised – Sometimes an extra level of protection for electronic components is required, such as marine applications or environments subject to dirt or dust. Our Ruggedised M1 hardware ensures maximum longevity under these extreme conditions

CONFIGURATION
The M1 series ECUs come with three configuration options.

boxes. Locked Configuration

FEATURES
? Small and light in robust magnesium enclosure
? Diesel and Direct injection control without the need for an external controller
? Large logging memory
? Latest generation high performance processor
? Suitable for modern engines with DBW, Cam Control and multiple CAN buses
A locked configuration is appropriate when an ECU contains specific firmware to suit the application. The user can tune the engine in the normal way but the ECU cannot be re-configured for another application.
Standard Configuration
The standard configuration allows the user to load a selection of firmware packages available from MoTeC. They incorporate different levels of functionality and the user can choose one to suit their requirements. Additional packages can be loaded into the ECU as and when requirements change.

? Advanced logging features, high speed, multiple logs (with Open Configuration
