Questions about the Continental IO-520/550
Of course, all of this would be history with a decent FADEC - one that has yet to be developed, in my opinion.
Imagine a controller that would give you best BSFC on every cylinder no matter where you had that single lever...
It's a crying shame that there's barely a brass razoo to be made developing such a system.

206H with IO540, correct. Majority of the time between A070 and A100, at these altitudes 50o LoP and 2350 or so gives around 132kts at 48Lph. On the flipside, 100o RoP and 65Lph (about 2600 rpm) gives 150+ knots - ill take the speed. I have spent hundreds of hours recording different power settings and fuel flows and their resultant TAS.
None of those figures are set merely serving as an example, as on a 4 hour leg I can't help but fcuk around in the search of perfection. The difference between 75 and 100o RoP is is about 2-3lph and with what I've read 75o is starting to get close to dangerous at what I would consider a fairly high power setting of 2650 or so and say MAP of 22.5.
If you get these seminars up and going count me in, good luck convincing some of the dinosaurs I've flown with to think differently though.

This is with standard Lycoming injectors, horrible for lean of peak - by the time the richest cylinder reaches 50o LoP the leanest one is hardly firing. The engine monitor on the G1000 is utter rubbish too and doesn't help the cause at all, I'm sure GAMI's and a better engine monitor would get the fuel flows down significantly.
Has anyone done the maths on how long it would take to break even on say a PA31 if you purchased GAMI's and an engine monitor?, I'm sure it wouldn't take long as you could probably get your cruise fuel flows down to say 130lph at the same TAS of 175 or so or a higher TAS of maybe 185 for the original fuel flow of 145lph. All the while running the engines much healthier.

Seriously dooode
And believe me I am taking the piss here, but I mean it as the best of mates, WTF are you doing that for, no wonder you are going slow
I will PM you my phone number so please call me!!!!
For everyone else watching, if I had that engine, I would go visit a mate in YPPF and fix one or two injectors, and then run the richest at peak. Life would be awesome.

The Deakin article "Analysis of an In-Flight Engine Failure" is a great example of this. People have argued with me about the safety benefit of a monitor, sometimes stating examples from their flying of when one didn't help, to which I was too polite to suggest they didn't know how to use it properly.
Ask a new instructor why the engine runs rough as you lean past a certain point. I bet 99 out of 100 wouldn't be able to tell you. I'm grateful that this forum provided me with the inspiration to learn until I could answer questions like that.

For anyone else watching this
And.........
I doubt you are in danger margin at anything above 7500, at 22" regardless of RPM you can put the mixture anywhere.
I stress again EDUCATION.
"It is not what you dont know that hurts you, it is what you know that is not so!"
Sounds to me like you need some minor injector tuning, and some education, and you will be right on it.
I must stress one SERIOUS thing here, the education side of this is more important than just fuel savings, you can install all the good gear you like, but if you do not know what it all REALLY means, you are no better off.
Engine fault diagnosis can save you thousands, just by knowing what the EMS tells you. your LAME will be stunned, and your bills far less.

Bob, you would be amazed In fact please do not be offended as that seemingly silly question is actually a pearler.....see this shows that you do not know what you don't know, and please no offense meant, but there would be heaps you could benefit from. trust me, I have helped educate some FP O360 and O320 owners.....and one with no EMS either. Mind you it is harder!

I have a small queue in front of you, and as yet I have nothing on the table, but I have been talking to a few local folk about this, and while it will be a charitable event I am sure, if we get it off the ground in the coming year or so, I would expect you would be up for around $1K here as well. But money well spent.
Time will tell. Appreciate your interest.
Great thread but ..... Where does this leave me with my 0360 with CSU and red gap in the green on the taco?

I'd sign up for this course. I stumbled upon Deacon a few years ago and it seems a shame that no one is doing something similar here.
Time will tell. Appreciate your interest.
Jaba, the question was not meant to be silly, I am serious. When can I do a course ... And where does it leave us folk with carbys, any notes or info on these engines?

You will note I said seemingly silly question, I realised you were being serious, and your exact question about folk with carbies is a good one.
For carby folk, the engines are pretty much the same, the fuel is the same, so 98% of the APS seminars still apply, they teach so much more than just how to run LOP. Although most folk think that is all they teach. You get a holistic education that applies equally to ROP operations, just how to do them right as well.
As for local training in Australia, might be a while off yet, I have been talking to a couple of key people about this, and my preference is to do this with the APS guys somehow, but I need to do this face to face in a few weeks time. I have discussed this in writing in the past, but face to face is better. If nothing works there a couple of us here have the job in front of us to develop a home grown version, it would be a little while before that could happen.
Andrew Denyer and myself have some seminar material which is just an insight into the value of EMS and how to gain more from them, this is oly a couple of hours but I can assure you the Q&A after my last two went for 1.5 hours so there is great demand for even that little bit of discussion.
The next time I do one will be with Andrew Denyer at AUSFLY in September and he does have a classic customer data file to share
a genuine event that happened in Adelaide, you could swear it was straight from the APS training materials, so if you can book yourself in for the Ausfly weekend.
If you want to talk more PM me with your number.
Folks this might be a year away, or may never happen, if we do it, and my legal friend who is watching his thread to, suggests there are a number of things we need to look at, or more the point he does, so easily this will cost us lotsa money, so be patient, and be prepared to fork out a fair chunk of cash. We will not be doing this to retire on by any means, you know how to make a fortune in aviation
. So it will be a cost recovery exercise for the better health of GA, not our wallets.
I see there is a thread for Ausfly, no firm timetable there yet but we will present the engine seminars both Friday and Saturday so when their website is updated you will know more.
And thanks for the encouragement, it's great to see you all wanting my to put my money where my mouth is
