Injector Flow Rate vs KPA... Hey guys, I'm doing my first tune ever and I hit my first roadblock (already, lol).
My injectors flowed 40.17 lbs @ 3bar, 80% duty cycle, so doing the math, I get an adjusted flow rate of 45.58 lbs @ my 56psi. My question is, for what value on the IFR vs KPA table should I input the 45.58lbs and should I scale up or down from there?
Thanks

When adjusting the injector flow table, you do not take into account the duty cycle.
If the injectors flow 40.17 #/hr at 43.5psi, then they will flow 45.58 #/hr at 56psi.
If the injector flow table is for a 28.6 #/hr injector (@56psi) to begin with, then simply multiply every entry in the table by 1.594, which is 45.58/28.6....
