m74.9 259.3765 004-01 was spotted on https://en.wikipedia.org/wiki/GAZelle_NEXT which is produced in higher volumes.

They now have brand new off the shelf ECU units for under $200

Just put a few hours into Artery at32f435 port of rusEFI in a separate repo https://github.com/rusefi/fw-AT-START-F435

Makes little sense overall but to cool of an engineering challenge to pass by!
