F42 Series

*F42D Expected Release Q1 2017*

The F42 series ECUs are powerful yet compact units with all of the same LR features used on our existing families. Designed specifically where cost is paramount, this ECU can control engines from one to eight cylinders. A full range of Life Racing control strategies are provided including powerful data-logging and software for most engines including normally aspirated and turbocharged applications. The F42 is a total rework and uses a newer generation of processor ensuring code execution and position tracking remain priority.

The F42 is designed to control engines including, turbocharged, supercharged, vvt, vtec, nitrous, water injection and many more.

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