Anyone know what, or if, I need to change these injector 'offset' table when switching over to 30 lb SVO injectors ? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Thanks,

I didn't, but that doesn't mean that it is the right answer. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> This bumps it to the top.

Batmobile, did you type this in as well as multiplying the injector scaling table through by 138% (assuming you have a 99-'00 LS1 w/SVO 30's?)

I did the 138% on the flow and tried a straight 125% multiplier across the offset table. This got me close on LTFT but I still had other issues with O2's and KR. The offset scale I found as "I" understand it is the Volts/Offset value at the 0. It does not account for vacuum across like the table in LS1edit. This has to be calculated. I gave up on injector offset for now and went to the MAF table to get my LTFT close to zero. I am close using 105% across. I do need to tweak it some across the frequency. My O2's went up and I am better on KR but still some there above 5500 RPM. Any ideas on the WOT relationship of Fuel Cell 15 and 22? I used to be almost always in 22 now its 15 with some switching between the two over a long run. I can't stress enough to make samll changes and test
