42# Green Top Injector IFR

Does this IFR look good.
Car is Stock Pump Running with Bosch 42# Green Tops (high Z 440cc)

i have been reviewing old posts to see what others are using.
but i am unclear on if some of those people have stock or aftermarket pump's

Attachment 12771

the reason i ask is my VE table is close to stock and the car is showing lean AFR often.

well i have done some further research still no answer,

but some intresting finds.

my injectors are:
SVO 42 LB

Bosch PN 0-280-150-558
40 LB/hr
420.4 cc/min
302.4 g/min

thats at 43.5PSI (3Bar)

the Stock Injectors that came with my SS are:
PN 0-280-155-890
Bosch
16.35 LB/hr
171.8 cc/min
123.6 g/min

thats at 43.5PSI (3Bar)

So why does the Computer show that the stocks are 26LB, is the fuel presure making that much diffrence in flow rate?

if so wouldnt this mean the 40#'s would flow alot more than i have in my tables when at the higher fule prusure. which i hear is around 58PSI.

correct me if im wrong.
i want to fully understand this and maybe help some of the other newbies too.

thanks

Yes, fuel pressure makes a HUGE difference in flow rates, that is what it is all about. Did you adjust the offset tables?

no i have not changed the offset.
any recommendations on best way to change them?

this is the information i have found for my SVO 42#s

V - ms
6 - 4.986 ms
8 - 2.098
10 - 1.321
11 - 1.095
12 - .919
13 - .786
14 - .670
15 - .575

how do i get that over to the chart?
