i tried my old home made dwell meter again and it worked this time, i don't know what i did wrong last time i tried it.
Any how, i turned up the pot that adjusts the needle to 100% 'duty cycle' to maybe 125% and i got pretty good correlation with my flow meter.
10% was ~1 gph and 20% was ~ 2 gph 30% was ~2.9gph and so on.
And the response is immediate, almost too fast, because at idle the needle bounces.
As before, i was thinking, if there was way to add two injectors together, the needle would be in the center of the scale and more stable. my meter is 1 MA full scale.
