[Diy_efi] EMS inputs/output?

[Kent Martin]

Bill,
I got some info of injectors from someone on this post,
thanks whoever you are!
I am not doing a research project just a rev head one.
I'd prefer to do use the 20Khz pwm first so I don't have to
put the resistor in the circuit.
Thanks for the attack on my knowledge, refreshing!
Kent.
