It was pointed out that some of these injector ratings are at 80% duty cycle, which will throw us off quite a bit..

Anyway, you actually need to divide the 1250 sec/gal by 4 (1250 seconds to flow one gallon through one injector, 312 sec when using 4) This still isn't a proven way of determining the constant, but right now it seems worth a try..

Also check this post http://ecomodder.com/forum/showpost....&postcount=105
for what I think is a way to get an idea of what uS you would expect to see when at a steady state cruise (if you have a decent idea of what your mpg should be at that cruise speed)

I haven't checked my injector for power when key on, so I haven't made any progress in solving my low uS problem.
