Default fuel injector upgrade..../hptuners/????'s

ok if I'm not mistaken you take the lb hr of the new injectors divided by the old ones "42/28" and multiply the ifr table by that.... what I need help w/ is where the ifr table is... am I in the right spot?(circled in red), any help here would be awsome

Yes that is the table. There is a conversion tool there that will make life easier for you. First off you have 26 lbs/hr injectors@ 58 psi

The conversion tool will let you enter your 42 lbs/hr@43 psi and convert it to 58 psi injectors. The number you get you will take the two divide it by 26.41 and multiply the percentage across the whole table and you will have the values for you 42@3 bar injectors...

Current inj = 42

The rest stays the same. The number you get as the answer is gonna be divide by your 0vac value which is 26.41. Also you dont need to convert to g/s (edit used that convention) Tuners represents fuel in lbs/hr jsut liek the injectors are rated

Anyone know how to take the lbs/hr and change it to where i can input it into Edit??

48.78 lbs/hr/ ?? give me the reading i can use edit software? Im using this to flatline my A/F and use my boostreferenced regulator to control the fueling needs as vacuum increases or decreases in the manifold.



TIA

Mike

ok I got around to putting the injectors in tonight, man there huge compared to the stockers... I used the tune just like that last pic I posted and the car started right up and accually was idleing smoother than stock, drove around and I could feel a touch more power, I wasnt expecting that... so the tune ended up being perfect, if I have any issues at WOT I'll be back on here asking for help....... thanks again HumpinSS


btw... V6 Bird..... I think the number your looking for is 6.15
