Al, I can tell you from personal experience that should the manifold pressure hose to the EC2 sensor become disconnected, the engine will continue to run - you probably wouldn't notice unless at idle rpms or under boost. True it would be rich except for near WOT, but it will run without any problem. Detonation would likely occur if you were under boost and there were no manifold pressure reference for the fuel pressure regulator to increase the fuel pressure proportional to the boost level fuel requirement.

Subject: [FlyRotary] Emergency Checklist

You’ve got Tracy’s EC2 and EM2. You’re flying along and the engine suddenly quits. After you establish glide, think about which way to head for possible landing – What’s the first thing you do? Second thing?

Electrical still on

Possible failures:

Fuel pump

ECU

One set of injectors out

Fuel supply interrupted (broken/plugged)

MAP sensor line broken (Would engine stop, or just get very rich?)

????

I think: turn on backup pump and switch to controller B. Check for fuel pressure, if not, set up for landing. If so, try restart. No start, turn off one set of injectors. Still no start; switch to other set. Then ??

Anyway, just thinking out loud. It would be helpful to see emergency checklists regarding engine issues from some of you guys flying. Tracy, you’re first (well, you can decline). And maybe one of you other guys who has also chosen not to fly through the prop wash (Can’t see whether prop turns or not).

Thanks,

Al
