Hey just looking for A15 hp figures, stumbled across this.
It is a concrete pump using an a15 engine with efi that has a single injector at the throttle body.

Alternate EFI manifold anyone?

Ah, Zenith ZEEMs off-road EFI. It's a good system, about the size of the original carburetor and runs at four different speeds.

I wonder how it would handle 15psi or so

I would consider retrofitting one of these to my stocker.
You could hide it under the stock air filter maybe?

It has fly-by-wire-throttle. Or in other words, no throttle cable.

The 4 fixed rev speeds is probably only good for pumping or other industrial appsthough. I wonder if any one knows of a tbi system that would work on a datto on such a way that it can be hiddn. I'd like the reliability without the bling.

u could try camira tbi

It might be as simple as re-routing the circuit of the controller to a simple variable resistor mounted on a shaft with the standard carbie's throttle wheel and a spring.

Im sure you could knock that up for under $10 with a trip to dick smiths / tandy / radio shack.

2 hour job??

Would be a laugh if it worked, they claim a lot about the fuel efficiency / emissions with that zeems setup... good for a daily driver...

EA falcon tbi might be easy to adapt as well, the tb should bolt onto a dgav adapter. Not sure what else is in the system to make it run though.
