Engine Control Units
The top of the range Pectel MQ12 is designed to function up to a maximum RPM of 22,000. Launched in 2008 to replace the highly successful range topping Pectel T10s ECU.
The MQ12 is derived from a bespoke development for the 2009 Formula Nippon series and has been successfully racing in Formula Nippon, the Le Mans Prototype series and the new FormulaTwo championship. It is based around two floating point processors - an MPC565 and an MPC5200. These processors are joined together, and to the ECU's I/O, by a very powerful field programmable gate array (FPGA). This FPGA provides the entire angle based processing capability for the ECU and reduces the work load on the ECU's processors. The FPGA also provides the advanced knock control.
Twenty configurable injector/PWM drivers combined with twelve IGBT ignition outputs and sixteen logic level coil driving outputs make this ECU capable of fully sequential fuelling on normally aspirated, turbo and supercharged engines including V12 and W16s. Fully software controlled with no hardware or cost options. Strategies within the ECU as standard are well developed for professional applications including:
- Traction control
- Launch control
- Performance based knock control (advance and retard)
- Variable valve timing
- Drive-by-wire throttle (also referred to as FBW)
- Variable geometry intake system or exhaust system
- Semi automatic gearbox control
Key features of this ECU are its extensive I/O, highly advanced knock control strategies, dual processor technology for future developments plus a code base that's developed from the proven SQ6 family.
It includes with no additional cost - advanced software features such as closed loop knock control, traction control, launch control, gearshift strategies including semi-automatic paddleshift control, variable valve timing of up to 4 camshafts (including BMW VANOS), high speed data logging and scrutineering modes for single make championships. Integration with Pi Sigma and Hyllus is a truely formidable package for high level applications such as prototype sports car projects.
Standalone the MQ12 is ideal for applications such as MotoGP and single make championships.
Two lambda sensor inputs are provided, which will accept NTK/Bosch style wideband sensors and narrow band sensors, along with eight specialised knock inputs with a software enabled gain stage.
