Hello everyone,
Now that i have decided on a PIC for my dashboard/logger circuit, i would
like to ask if anyone out there has a circuit which can interface a fuel
injector pulse signal to a PIC input?

I have found the circuit to interface it to the points, or coil output of the
car, but nothing so far for the injectors.

Can the same circuit for the points be used for the injectors? I have seen
one example on diy-efi using optocouplers, there has to be another way
though.

Te circuit would connect the injector pulses to a PWM Capture pin on the 877
to measure time high and low and show the pulse width in milliseconds, and
also show duty cycle.


Daren
