I moved the op amp circuit and the flow meter circuit
 to the main mother board. I also added an on board 5 volt
regulator
 and some CAS trigger conditioning circuit.

I want some.

Wade Bush

I'll probably get some pricing tomorrow. I will sleep on
the design
and check it again before I send it out.

Good thing I checked it. Found one mistake.

Here is a lot of stuff. Feel free to ask questions.
Next step is the mother board and a bit of work on the op
amp.

Is any body interested in a low cost kit of parts? No
credit cards and
no checks. Just green cash :)

You will become part of the 555 EFI R&D community so
there are no guarantees of any
kind :) This system as not run on an engine yet.

Yes, I'm all in for a kit of parts, saves time and trouble for a lot of issues.
