Default Megasquirt II Fuel Injection

I'm using a do it yourself fuel injection computer called Megasquirt II . I purchased it as a kit and then soldered all the compnets to a circuit board provided in the kit and then down loaded the driver software from their web site and then programed it to suit my motor.
The Megasquirt II also controls the ignition timing which is all adjustable by the user.
This system is very adjustable for manifolds pressures, rpm, spark advance, etc.
When I fly there is nothing to do but fly, the manifold pressure sensor adjust the volume of fuel as the manifold pressure changes. There for it is great for turbo charging.
Do not think that I'm some sort of brainy dude, I had to learn all this by reading all about it and carefully reading the directions that are on the Megasquirt site. I started out by knowing nothing just like when I started building my aircraft, in fact the Rep. at Van's sugested that I get some builders assistance because I did not even know what a cleco was. I never did get assistance, I learned by reading Van's directions in their builders manual and by looking at other builders wed sites..

Cool project. Congrats on building all that and making it work! I used to own Corvairs and build engines for them- turbos and road racing ones so I have a soft spot for them. Nice to see one in an RV.

That's just too cool. It's hard to keep from looking for a Lear Jet in the background when the sound's up while viewing the video. :-)

Way to go!

There's a lot of different kinds of smarts... I respect that kind most.

Default Corvair Power Now!

Robin: Fabulous job on the installation and final tweaking to make it a "turn the key and fly" a/c! If i remember right, you used to have a GM ECO engine in it didn't you, with the less than sexy looking cowling. Why did you do it again after getting that one flying? Also, what performance differences have you seen between the two installations? Is it harder to make some heat for the cabin with air-cooling vs. water?

Great job, and fly safe!

Doug

It is a Catto prop. 66" long 60" pitch counter rotation. It was damaged on my second forced landing so I repaired it using vacuum bagging process and it is working great.
So far I have 112.2 hours on it.
Here are a few pictures of the installation of the motor. Yes it has fuel injection too.
I use Mobil one synthetic oil in it 10-30wt.
The crankshaft is made by Corvair Specialties, it is 4340 steel billet that have been line-bored, undercut pendulums, knife- edge machined, and partially drilled rod journals, all to keep the weight down to a mere 2oz. heavier than the original crankshaft. The crankshafts have also been heat treated, shot peened, nitrided, and micro-polished.
Robin,
First, very nicely done!
Question: Did you consider the 5th bearing mod from Dan Weseman at Panther SPA and/or attend any of William Wynne's Corvair U forums before developing your engine?
