I took Tracy's EFI out of Mike Wills RV4 and can't get it to
work on the bench. It is getting a good CASsignal as I have
a drill motor driven 2nd gen CAS. It was working in the airplane.

I would be nice if Tracy had put a couple of LED's here and there
to reassure something was working.

If I ever design and build and EFI I will surely do that because
it is real cheap.

I am open to suggestions. I checked the wires and they seem OK

Will it work with out the PCM connected?

The relay works that selects one of the two computers.


I want to measure the dwell period  Tracy choose.
