[Diy_efi] RE: 555 timer controlled EFI

[John Smith]

The complex circuit with a bunch of sensors for a multi cylinder engine, or 
the simple single cylinder version? The simple one is just a monostable 555 
timer with a variable resistor and the chip output to a power transistor for 
the injector.

On a side note for anyone that noticed I havent been active for a few 
days...I decided to use only a TPS for pulse width variation. I have the TB 
from a Nissan that starts at 8.6K ohms closed and ends at 2.1k wide open. 
I'm going to use a trimmer to get that up where I can use it. My pulse width 
will only vary between ~3mS and 9mS per revolution(batch fire config, albeit 
only one cylinder).
