My car is running pretty lean. I have yet to buy a wideband as I had just got the car back together from a buildup. It is currently running bone stock fuel with no by-pass mods (will do asap), and no 12v mod. I was advised not to do the 12v mod for some reason.
The turbo on the car is an sp63 .81 on an HKS header. And I am running the 1 bar spring out of the GT gate with no boost controller. I cannot boost past 1 bar.
I thought this would be safe, and my vpc settings, and gcc settings are set to zero as well.
When I checked my plugs they are black around the ring and pure white on the tip. Sp I am running lean as hell right now.
I turned up the gcc settings up all the way across the board, run the car and check the plugs and they are still white. So I play with the gain knob and turn it to +9, I am still getting pure white on my tips. Even driving it for 10 miles on zero boost I still have the same white results.
My questions are, is 1, I do not have my 2nd O2 hooked up. It is completely disconnected. Will this cause my car to lean out this bad? What else could it be? I am currently putting together a fuel system but I'm just annoyed because its only at 1 bar. Any input would greatly be appreciated thanks.
