F88 GDI4


The F88GDI4 ECU sets the benchmark for integrated direct injection engine management. Based on the F88 architecture the F88GDI is by no means a compromise it just has less inputs and outputs for those GDI applications that don’t require the complexity of the full F88.


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 the scheduling of code to be independent of signal patterns, increasing flexibility, efficiency and accuracy under transient conditions. This powerful combination also allows advanced control algorithms but yet easy to map for the end user.

The F88GDI4 is designed to directly control and drive all GD injectors including parts from Ford, GM and Bosch (including Bosch Motorsport types) without the need for an external driver box including, turbocharged, supercharged, drive by wire, twin cam, twin vvt, vtec, gearbox, differential and many more! The unique crank and cam sync logger allows the flexibility of controlling the most awkward trigger patterns capable of running all current known patterns and even future OEM timing wheels.

This powerful hardware is packaged within a lightweight CNC billet aluminium case. Designed to be installed in the most harshest of motorsport environments.
