Subject: [FlyRotary] Engine = tuning, part=20 1

Greetings,

I made an = attempt at=20 tuning the engine today. I'll continue to beat my head against = the desk=20 as you read my log entry. Thud, thud, = thud...

Rusty

PS- I'm going = to try=20 unwrapping some of the trigger wire on the tiny tach tomorrow, so that = I only=20 have 4 turns as the instructions suggest. It will either help, = or=20 not. I'm pretty disgusted about this whole tach thing. =20

Rusty, to=20 make you feel a bit better while you beat your head against the = wall. =20 After I got my EC2 reprogrammed for some of the new added features a = year or=20 so a go, I reinstalled it laying on my back with head under the = instrument=20 panel. After much threshing about getting the board past the = vacuum and=20 electrical lines, I put the retaining screws in. For the next = several=20 days, I couldn't get the engine to run right, too lean at high rpm and = too=20 much fuel at low rpm (sound familar?).

Well, got on the phone to Tracy, who after = some=20 discussion asked if my manifold pressure lines were attached. I = assured=20 him they were as I had pushed both through the holes in the case until = they=20 were snuggly attached. Well, problem continued despite eveything = thing I=20 tried. Since the problem was the same on either processor, I = concluded=20 that either I had two bad manifold pressure sensors or something had = gone amis=20 when Tracy had reprogramed the EC2. I crawled up under the = instrument=20 panel and confirmed to Tracy that the manifold hoses were still = attached,=20 even tugged on them to make certain they were on the = barbs.

Finally, I decided that I had to send the unit = back to=20 Tracy as I was getting nowhere. So again flat on my back up = under the=20 instrument panel, I loosened the screws holding the board inside the = case and=20 gentle lowered the panel. As I lowered the panel I happend to = notice=20 that the pressure sensors were on the opposite side of the case from = the holes=20 for the hose. Duh! when I had replaced the board, in = wiggling it=20 past vacuume electric lines, I had managed to get it reversed 180 = deg =20 (square case - so it fit just fine). The resistance that I = thought=20 indicated the hoses were on the barbed manifold pressure fittings were = actually the hoses stuck under/between components on the = board.

Needless to say, it was somewhat = embarrasing to=20 report back to Tracy that after assuing him the hoses were attached, = turns out=20 they were not. But, Problem solved.

Just thought this might make you feel better=20 {:>)

Best Regards
