It appears to depend on the module - some let you get away with it and some don't.

ok, i have it all hooked up. but signal is working but on/off, i have a drill hooked up to my distributor, when it is reading, i can rev the drill and the rpm is consistant, but once i stop spinning, then i have to spin the drill twice to get it reading again,

or if i even spin the drill backwards it starts working right away.
