The simple answer is yes. Especially with a gear tooth type hall sensor.
But, I want a sharper rising and falling edge. A very simple flat tab with a 90 bent into the end will work. Possibly cut off material on either end of the polled area to create loss of signal. BTW, the Chevy Vortec dizzy uses a poll gear arrangement as well. It's another one to look at.
I actually have a modified front cover that also works, but it's not as simple as the fuel pump block off. It requires precise positioning and the possibility of cam trust can affect the min/ max free air tolerance. The easiest answer is the oil pump drive/ sensor. All in one, wiring to the rear of the block. This is why I considered the Ford Explorer sensor. Again, easily accessible to replacement parts and cheap to boot. The hard part is grafting the pieces together and I have attempted to source some dizzys for this purpose.
I will be machining the parts at work, but I am trying to come up with a dirt cheap, DIY for the masses method of doing this.
But
at hand, Where's our EFI specific forum?
