Maybe for your injectors, not for the ones I used.  My understanding is
that those numbers will vary condiserably by injector model and how the
injectors are driven.  I believe our idle pulsewidth was right around
1.0mS on our 93 F-SAE car (600cc ZX-6D, Camden vane blower, EFI
Technologies Performance-Series ECU, 31lb/hr Rochestor injectors (from
a flex-fuel Corsica), running M85, rev-limiter set at 15,000rpm).
