From the project

FOME 112-pin Universal ECU

This is an open-source ECU base board compatible with Polygonus and Atlas ECU brain modules.

It is intended to be wired-in to a custom wiring harness, or an OEM harness with the connectors cut off and replaced.

- Dual wideband O2 sensor controllers using open source module (connected internally to CAN bus #2) - Dual VR crank/cam sensor inputs. VR input 2 uses adjustable threshold, suitable for low tooth count (single tooth cam, etc) applications (LS12 unavailable if used) - 11x analog voltage inputs (weak pulldown to ground to avoid floating) - 4x analog temperature inputs (2.7k pullup…
