Ray, Can you relate "late as possible"and "early as possible" to engine events?
I don't do much cold engine work considering most of my work is on race cars. If it is too cold, they don't come out of the trailer. However, for a warm engine, we are typically firing our idle pulses slightly before the intake valve open event and our wide open throttle pulses are ending before the intake valve close event. I know for a while it was Ford corporate policy to not fire on an open intake valve due to bore wash concerns.
