Anyone know of or have any idea about a EFI for the Onan generator?

Interesting but short video.
Any more information on the setup?

The belt drive model (Forget the name) from Onan was offered carb or for another hundred injection. We put the injection ones in our new vehicles. Instant start in all weather even if it hadn't been run in a month or so.

Bruce,
Thanks for that link: I really hadn't thought through the requirements to
do the job right -- it's a LOT more complicated than my first thoughts
considered!
I couldn't find a typical cost, but it's bound to be far above anything I'd
consider, since I'm not likely to ever "hot rod" anything again, much less
anything that small.
By the way, what IS the Onan's displacement?

I looked in the Onan manuals and it does not give the displacement. However the bore is 3-9/16" and stroke is 3". So that works out to 29.9 cubic inches per cylinder x 2 = 60 cubic inches or 983 cubic centimetres (CC's) so say 1,000CC's which is 1 litre.
Unless I calculated wrong, it's a bigger engine than I thought!
They show a Briggs & Stratton Vanguard 993cc kit, but it comes with an intake manifold. Their universal kits show up to 800cc. Since the Onan runs at a constant 1800 rpm, a kit for a smaller engine will likely work since we don't go WOT!
My Onan works fairly well, but it is smelly. I think a catalytic converter would clean up the smell, but they are costly.
Maybe someone will chime in with the cost of a kit.

I was at burning man 2022 and the governor on my Onan 6000 got caked with dust after running 30 hours.
I think an electronic governor and some way to filter the dust without loosing cooling might solve my problem.
EFI and electronic governor should be a good solution.

I have 20 or so pages on our blog about the setup under Onan efi links. https://wallyandsue.blogspot.com/
Been messing with it for a few years and since we pretty much are stuck at home it got finished. Interesting fuel tune because it runs at 1,800 rpm or off. It's running fixed timing from a battle proven Ford VR crank sensor. I'm using the original carb as a air valve with the choke fixed open and throttle position sensor attached. The governor works exactly like before with the same linkage and valve.
I couldn't find a reference to 'Onan efi' by doing a search on your blog, and the videos were no longer available. Can you send a specific link to that info perhaps?
Cheers,
Bill
