Life Racing F90RX Engine Management System (ECU)

From: £3,776.00 (+VAT)

The Life Racing F90RX ECU has been introduced to allow easy and cost effective control for high pin count challenging applications. This ECU is available with 3 full bridges and can control up to 12 cylinders fully sequential.

For full specification of this ECU, please see the description below the ECU configuration options.

Configure your F90RX ECU:


The Life Racing F90RX features a twin processor unit which use a high-speed RISC processor for code execution and an additional large FPGA for high-speed engine position tracking. This allows 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 F90RX is designed to control complex engines including, turbocharged, supercharged, twin drive by wire, quad cam, quad vvt, vtec, gdi, gearbox, differential and much 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. Designed to be installed in the harshest of motorsport environments.
