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

^^ Thank you, good sir.

 

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....

 

^ I wish I could just multiply the table by 1.594; unfortunantely someone "tuned" my car already and yucked up this and a few other tables.

 

shoe,
thats a keeper spread sheet

 

It's been around for a long time,
here the other one that scales by measured fuel pressure.
