Babych44 Posted February 2, 2020 Report Share Posted February 2, 2020 I´m changing from traditional to modelled fuel and have new (used) injectors. Injectors are Imprezas yellow sidefeeds and they are rated at 440cc, but I had them tested and were about 500cc at 3bar. Should I put 440cc or 500cc to "injector flow" I want "instant fuel consumption" to show correct value. Also are the dead times same than grey "380cc" injectors? Car is Impreza GT 1998 v3-4 Quote Link to comment Share on other sites More sharing options...
motomattx Posted February 3, 2020 Report Share Posted February 3, 2020 You would use 500cc if thats what they flow at the pressure that you are going to run. Quote Link to comment Share on other sites More sharing options...
Babych44 Posted February 3, 2020 Author Report Share Posted February 3, 2020 Yes the fuel pressure is same 3 bar Quote Link to comment Share on other sites More sharing options...
Davidv Posted February 3, 2020 Report Share Posted February 3, 2020 Definitely put in the tested value. If you want really good accuracy though then it's good to have a fuel pressure sensor so it can work out the fuel pressure differential accurately. As mechanical FPR can fluctuate a little. Your deadtimes being accurate will be a big make or break for accuracy of your fuel consumption though. Babych44 1 Quote Link to comment Share on other sites More sharing options...
rrob Posted February 3, 2020 Report Share Posted February 3, 2020 Those injectors have a dead time of .67-.68 ms at 14v. Babych44 1 Quote Link to comment Share on other sites More sharing options...
