Hi again Finn Pretty sure the EM3 requires injector pulse input for tach and fuel flow. See the pinout/in instructions: TB4-3 TACH & FUEL FLOW SENSE FUEL INJECTOR 1 LEAD ON EC3 & FUEL INJECTOR The previous pin is for engines without an EC2/3 for their Tach.

Fuel pumps started leaking badly around O-rings when I adjusted fuel pressure up to 37psi (engine not running). Pooled up in fuselage. Need to fix before I try running again. Gas is cheap, but not that cheap. I'll try copper washers on the pressure (output) side instead of the o-rings. >> <hdhnppaldlddbemj.jpg> >> Yes, I know, not pretty.
