F90A

The F90A ECU is the entry level unit that utilises Autosport connectors, it is based on the F90RX design and has been introduced to allow easy and cost effective control for high pin count harsh environment applications. This ECU is available with 3 full bridges and can control up to 12 cylinders fully sequential.

The F90A ECU caters for advanced and challenging applications. The 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 remains easy to calibrate for the end user.

The F90A is designed to control complex engines including, turbocharged, supercharged, twin drive by wire, quad cam, quad vvt, vtec, gdi, gearbox, differential and many more! The unique crank and cam sync logger allow the flexibility of controlling the most awkward trigger patterns capable of running all current known patterns and even future OEM timing wheels.

All of this hardware is packaged within a lightweight CNC billet aluminium case with Autosport connectors. Designed to be installed in harsh Motorsport environments.
