yeah, they gave me an offset table as well.
for the high slope, i took the 10ms pulse and multiplied it by 3600 (60seconds in a minute, 60 minutes in an hour) giving me the lb per hour at what i'm assuming is 100% DC
the low slope, i took the breakpoint, and multiplied it by 3600 (getting into hours again) and then multiplied it by (10/2) (assuming 10ms is 100% DC, and 2ms would be a 20%DC)
the low slope was where i was getting confused, because if i used the two points they give me below the breakpoint, then i get way different results. one will be 79 the other will be 56, which is why i'm using the breakpoint now.
The math works on all the flow numbers if you make sure to multiply out the percent duty cycle assuming 10ms PW is 100%. So all the numbers above the breakpoint give a similar outcome (slight variances)
for 39psi i got 68 hi slope and 58 low slope
for 43psi i got 66.6 high slope, and 66.08 low slope
I was hoping someone knew of a program or something to input the flow data and spit out slopes. I think EEC analyzer has a flow table like that in the fuel injector section, but I don't have a license to test if it will turn that data into slopes.
