The SQ6 sets the benchmark for high-performance engine management systems. Its unique strength lies in it being hugely powerful yet easy to map, using a powerful processor coupled to a FPGA that handles all angle-based operations. Utilising an FPGA brings a host of advantages against other ECUs; namely improved engine control as critical angle-based functions are not delayed by CPU interrupts.

Advanced software features include (but not limited too) traction control, launch control, gearshift strategies, variable valve timing of up to 4 camshafts (including BMW VANOS), VTEC/VVL, Electronic Wastegate control, dual FBW, engine protection and high speed 1kHz data logging all developed and enhanced over the years of Cosworth’s motorsport involvement.

Twelve configurable injector drivers combined with eight IGBT ignition outputs and eight logic level coil driving outputs make this ECU capable of fully sequential fuelling on normally aspirated, turbo and supercharged engines from one to twelve cylinders.

The SQ6 is hugely flexible with two, and sometimes three functions on many of its pins:

• Unused injector and IGBT ignition outputs can be used as digital outputs
• Unused digital inputs can be used as 10 bit analogue inputs
• H-bridge outputs can be used in either full or half bridge mode, H-bridge outputs can be combined to drive a stepper motor or used to provide additional high or low-side drive capability

Whilst closed-loop gearbox control is included out the box, optional highly advanced control strategies for paddle-shift systems can be added, with a multitude of controls for ramp-out/in, main cut and various FBW blip control strategies to improve shift speed, smoothness and gearbox reliability.
