LS1 edit and fuel pressure
 

I'm starting to tune my Twin Turbo car with LS1edit. I have an external fuel pressure regulator since I went with an aluminum tank with an external fuel pump.

My question is this:
My regulator compensates for the boost. Meaning that as boost goes up my pressure does also. Has anyone had any experience on LS1edit using this method? I'd be curious at to their results with it.

watch your 02s at the track/street on a 3rd/4th gear pull. 1st/2nd goes by too fast to get a good read as the os2 are kinda slow. You can then see where you need to work on fuel flow. i forget which table it is as I just got it yesterday but I did scale mine up i think .5 to get mine leaner across the board. I accidently copied the fuel map from a stock trans am and my strims were showing -35% at idle <img src="gr_eek2.gif" border="0"> needless to say I didnt even get it in gear before I was reloading the right program. So far I really like ls1edit and am enjoying the learning process. You should pretty much be able to tune the fuel injector table for whatever fp you are running as long as the fp/injectors are enuff to support the rwhp you are making

Flat line the injector flow rate for your flow at the base pressure.

I run a referenced regulator
