The Life Racing F90RX ECU was designed to provide simple and cost-effective control for high-pin-count challenging applications. This bulletproof ECU comes with three full bridges and can control up to 12 cylinders sequentially.

Our latest Life Racing F90RX ECUs are now available with control of two Bosch HDP-5 fuel pumps and multi bank independent drive by wire functions for advanced and challenging applications.

1 to 12 cylinders. On Ethernet at 100Mb/sec, all Life Racing ECUs support our full suite of cal tools, including LifeCal, LifeView, and LifeMon. UEGO lambda and DBW (drive by wire) applications are supported by all ECUs.

This twin processor unit employs a high-speed RISC processor for code execution and a large FPGA for high-speed engine position tracking, allowing code scheduling to be independent of signal patterns and thus increasing flexibility, efficiency, and accuracy under transient conditions. This potent combination enables advanced control algorithms while remaining simple to map for the end user.

The Life Racing F90RX is intended to control complex engines such as turbocharged, supercharged, twin drive by wire, quad cam, quad vvt, vtec, gdi, gearbox, differential, and many others. The unique crank and cam sync logger gives you the freedom to control even the most difficult trigger patterns while 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.
