Re: General engine tach. electrical characteristics?

Bob, that's quite a clever way of determining the RPM! That would be
great on an older vehicle with no dedicated CPS output. In my case
however, I plan to use the sensor already in place.

Mike, I do indeed have a FSM, and it has certainly been an invaluable
purchasse. The engine in my Nissan is also multiport fuel injected. In
my Nissan the engine will fire sequentially normally, but will fall
back to simultaneous when in 'safe' mode or starting.

You brought up a good point that I had not considered: the tachometer
gauge signal is probably analog. I would rather read the signal going
to the ECU, as you have planned. Good call there.

What frequency range have you observed in your Toyota?

Thanks to both of you for your responses.
