Leaning new skills - making a M111 harness

Post by AndreyB »

Jimmy has allowed me to touch his Hellen, it's a classic rev A.

Tune as arrived https://rusefi.com/online/view.php?msq=1426

Firmware is https://github.com/rusefi/rusefi/releases/tag/20220317.release or something very close to that date.

I suspect the other side of that says Bosch, no?
