F88GDi4

The F88GDi4 ECU sets the benchmark for integrated direct injection engine management. Based on the F88 architecture the GDi4 is by no means a compromise. This control unit features efficient use of its IO complement specifically designed for a modern 4 cylinder engine yet cost effective for GDI and CI applications that do not require the complexity of the F90 series controllers.

This twin processor unit uses a high speed RISC processor for code execution and an additional large FPGA for high speed engine position tracking, allowing scheduling code to be independent of signal patterns thus increasing flexibility, efficiency and accuracy under transient conditions. This powerful combination also allows advanced control algorithms yet remains easy to calibrate for the end user.

The F88GDi4 is designed to directly drive all solenoid GD injectors including parts from Ford, GM and Bosch (including Bosch Motorsport types) without the need for an external driver box. Standard strategies include, turbocharged, supercharged, drive by wire, twin cam, twin vvt, vtec, gearbox, differential and many more. The internal data logging coupled with a unique crank and cam sync logger allows detailed analysis of input, control signals and fault diagnosis.

This powerful hardware is packaged within a lightweight high pressure die cast aluminium case designed to be installed in harsh Motorsport environments.
