Engine is Mercury 30ELPTEFI outboard boat engine, 30/40 hp(depening if air restrictor is installed or not), 3cylinder, 4stroke EFI.
Has three individual coils, three high impedance injectors, crank trigger with total of 6 missing teeth locations, also cyl 1 has two teeth between missing teeth, cyl 2 has 3 teeth between two missing teeth and cyl 3 has 4 teeth between missing teeth. Most likely to identify which cylinder is firing?
Seems to be 84-2-2-2-2-2-2.
I can take photos of the flywheel, also have schematic diagram of ECU components and connections along with pin numbers.
