Wired up a Fueltech ECU = or the Megasquirt?

I have, in fact, had a = well running aircraft rotary engine with a MegaSquirt, and may again in the= not to distant future.

Bobby, for a secon= dary CAS, wire up a Ford EDIS-4 ignition controller to the trailing plugs. =  You don't even have to provide it with a control input.  It's li= mp-home mode is 10 degrees of advance. Set the CAS to have 15 degrees, and = your set.
