Twin Sync
I've just emailed Mark with a request, to see if that unit could be modified to work a little differently, like a full-size sync system (Raytheon - King Air) I just read about...
Instead of physically setting any particular engine as master, have the little computer monitor BOTH engines, and on a moment-by-moment basis, the one with the higher RPMs is considered the "Master".
In a perfect world, I wouldn't want to knowingly have a "weak" and "strong" engine. I'll be trying to break at least 2 engines in, under as close to exactly the same conditions that I can, and (ideally) get them VERY close, manually. Then, the EMS/Jomar unit would take care of the rest.
Twins give me a little "twitch", when I think about this stuff. Maybe we should start a "Multi-Engine tips" thread here, to collect some new information...
