those numbers aren't very well described <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

is it set up for SVO 30# injectors?

rated flow rate 39.15? Isn't it supposed to be 30?

are the numbers across the bottom (injector flow vs map) set up for 30# injectors? I'm running an OEM regulator

 

In the top block of the 3, enter "43.5" (psi at which SVO injectors are rated); in the 2nd block, enter the FP you will use (should be about 58 for stockers); in the 3rd block, enter "30" for you new injector size.

All the rest will fill in automatically. Take the numbers from line 25 and enter them across the table in your LS1Edit called Injector Scaling.

Make more sense now?

Actually, I think two of the boxes are labeled backwards if I remember. Answer these questions for me and I will give you what you need:

1 - Are you using a stock regulator?
2 - If not, is your regulator vacuum referenced?
3 - What FP are you going to run the injectors at

For #3 - Should be about 58psi if you have the stock regulator. Otherwise, it may be something else.

crap

those numbers are pretty much what I had entered <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Maybe my walbro pump is allowing a tad more fuel pressure (overpowering the regulator?)

I'm putting it on the dyno Friday to see. But its definately running pretty fat up high <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

 

Did you turn the cat over temp (COT) feature off?

I found that a 143% correction factor worked better for me than a 139% factor calculated by the spreadsheet, probably because I did not change the injector offset.

COT is off. WHen dynoing I'll adjust the scaling until the line is close then play with the WOT tables

 

Don't you have the Excel sheet that ChrisB made up? If not check here: http://www.speeddemonmotorsports.com...ectorscale.xls

Just plug in the numbers in the 3 boxes up top. The sheet will rescale the values for you. I have have very good luck with this.

If you running a stock regulator, then just plug the rescaled numbers right in across the board.

If you are using a vacuum referenced regulator, use the new base number all the way across the new scale and allow the regulator to maintain the appropriate FP.

 

Well if you are running very lean down low, it could cause you to run fat up top.
