Engine has 75 hours since MOH. Bendix fuel injection, Slick mags. Unfortunately, only one cylinder has EGT. Engine tends to idle a little rough and rpm's fluctuate and surge a little when below 700 rpm. It will idle as low as 350 rpm but doesn't want to stay there. Fuel pressure at idle is 30 psi. Since this is my first injected engine, I'm all ears as to the proper way to tune and set this engine up for proper operation. What is proper way to check fuel injector flows?

I would like comments concerning the following tentative decision. I have made a tentative decision to use one LSE electronic system and one Slick impulse mag would in an emergency allow a hand start. For fuel delivery I will use either an Ellison throttle body or one made by Aero Carb out of Oshkosh WI. Does anyone on the list have experience with www.AeroConversions.com and their Aero Carb? Thanks for your impute, Vic Roswell, NM ________________________________ Message 4 _____________________________________ Time: 01:56:54 PM PST US Subject: Re: Engines-List: Fuel injection/ electroncs ignition From: Kent Ashton --> Engines-List message posted by: Kent Ashton FWIW, why use an impulse mag? It will cost $100 more to buy and $100 more when you have to get it rebuilt at 1000 hours. -If the LSE is not working, you're probably not going to fly that day even if the mag will start the engine. -If a working Lightspeed won't start the engine, it sure won't start on the mag. I'm running a Lightspeed and one non-impulse mag. The mag has never been a factor. Successful starting appears to depend more on an adequate primer system, especially when cold. --Kent > From: "Vic Jacko" > I have made a tentative decision to use one LSE electronic system and one > Slick impulse mag would in an emergency allow a hand start. ________________________________ Message 5 _____________________________________ Time: 06:48:12 PM PST US From: "Vic Jacko" Subject: Re: Engines-List: Fuel injection/ electroncs ignition --> Engines-List message posted by: "Vic Jacko" Kent, some very good and valid points! The impulse mag is already on the engine but your comment that If the LSE gave up you would not want to fly anyhow. The real purpose of keeping one mag is to allow you to continue to fly for a while if the electrics gave up or the LSE quits on you in flight. I had a Lyc 0-235 with two LSE, s and didn't it miss a lick in either one for over 200 hours. Sold the airplane and the new owner is just as pleased. I plan to use a primer nozzle on each cylinder (four in total) Some engines use only three which I don't understand. My engine would always start on the first bump of the starter is it were primed properly. Thanks for the info.

Again I do not know this to be a fact or not, just what I have read else where.

The impulse mag delays the spark until TDC rather than letting it go at 22 BTDC, same as the LSE system. However, the electronical ignitions put out an impressive fat spark whereas the mag is a little wimpy at low RPM. That said, I used to hand prop my O-320. I thought adding an LSE was going to make it a breeze to hand prop, but it still wasn't a piece of cake when the weather cooled off. Not until I added a primer system did it reliably hand-start in a pull or two. I'm running two LSEs on an O-360. It always starts in 2-3 blades (with a Starter). --Kent > From: "Trampas" > From what I have read on other lists the LSE will only retard the timing to > TDC, which can be a problem for hand propping on some engines.
