Dunno, gotta do the math, depends on the vehicle. my saturn=5000 vss pulses per mile, maybe 80milliseconds per pulse at 1800rpm/40mph. 4 injector pulses per 2 revolutions.

It did occur to me that a number of folks have more than one arduino. It occurs to me that an arduino generating fake vss and injector signals for a mpguino would be an inexpensive and flexible test bed, as opposed to 555s.
