Pi Innovo introducing new M670 rapid prototyping ECU

Pi Innovo will launch its new M670 rapid prototyping engine control unit (ECU) next week at Engine Expo 2015 at Messe Stuttgart. The M670 is the latest in Pi Innovo’s OpenECU family of rapid prototyping ECUs—a family of off-the-shelf ECUs and software designed to take electronic controls innovations from prototyping to production.

The M670 is a 154-pin high feature engine controller designed to support gasoline PFI, GDI, diesel solenoid, and alternative fuel applications. The ECU supports a broad range of engine control features such as dual ETC, quad VVT, VGT, dual knock, UEGO (Universal Exhaust Gas Oxygen), HEGO (Heated Exhaust Gas Oxygen), and more.

Applications include common rail diesel; diesel exhaust after-treatment; GDI (gasoline direct injection); PFI (gasoline port fuel injection); two-stroke engine control; various novel\experimental engine technologies; hybrid vehicle control integration; supervisory control; or transmission control.

The M670 allows customization of production level hardware, accelerating speed to market for mainstream automotive development while also providing a platform for niche volume production projects from specialty vehicles to large engines and off-highway equipment.


In its standard configuration with its MPC5674F Freescale microprocessor, the new Pi Innovo M670 supports engines of up to eight cylinders and provides 120W of internal boost power for fuel injectors, accommodating multiple overlapping injections per stroke.

A total of 96 of 154 I/O circuits can be modified to meet specific vehicle application requirements and the unit’s smart software is fully adjustable to control a wide range of injectors for maximum flexibility.

The new M670 forms part of an integrated tool-chain from concept to production. As with all Pi Innovo OpenECU products, it provides the application-independent Simulink development environment to streamline the development process for production ECU code. Customers are therefore able to progress more quickly to a production solution, saving product development time and cost.

It can be used with a wide range of industry-standard calibration tools including ATI Vision, ETAS INCA, dSPACE Control Desk and Vector CANape via CCP, as well as Pi Innovo’s own calibration tool, Pi Snoop.

Like all members of the OpenECU product family, the M670 has been engineered for flexibility and robustness, suitable for use in the under-hood environment. This robustness together with its large amount of customizable I/O enables the M670 to be reused across successive vehicle product development projects, saving considerable cost in prototype hardware. Similarly, for niche or low volume (<10,000) vehicle applications, it can be customized for production use as an alternative to more costly bespoke ECU development.
