That is in my area of interest also. Cars and fuel modifications! Welcome back, I was not here before when you posted your previous creations. I'm catching up on your last posts from back in 2007...

Controlling 4 injectors? I don't see the drivers...

Are you running your fuel mixture more rich or more lean? Fuel additives?

Yes, 4 injectors , at that moment i use mc33385 (at upper left side) to drive injectors independent.
Old board use 2 pieces VNP5n07 - smartfet , one transistor drive 2 injectors per bank.

Currently I am using this system in my amateur racing car , so the fuel mixture is more rich than lean. To tune the fuel maps i use wideband oxygen senor and AFR type device, by which I can see what is happening with the exhaust gases
