[Diy_efi] RE: 555 timer controlled EFI

[Dale Mahan]

Hi,

Concerning:
"The complex circuit with a bunch of sensors for a multi cylinder 
engine, or the simple single cylinder version?"...

I'm more interested in the multi-cylinder EFI version.

Although it may also be good how to make a fuel injection controller for 
a one-cylinder engine.

Thanks,

Dale
