PWM injector driver

[Bruce Plecan]

What I did some time ago was

Let the ecm supply the over all pulse width.

I used that to trigger two power mosfets,  one had 8 ohms in series with the
injector, and then a 555 astable mode with no resistor.    After the astable
timed out then all that was left was the one with the 8 ohm series resistor,
and the the open signal of the ecm tuned off the mosfet.

Nother case of not enough heatsink, wook workbench, bad smells followed by
fire.
Hard to hide that from the better half.........
Drawfs are better at maintaining control inna emergency
