Fuel is fixed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Got my roommate who knows nothing about cars to come with me and help Datalog. I did 3 datalogs where we were pegging the wideband even after lowering the rate of gain and increasing boost, then the 4th blew an IC hose (which broke a headlight bracket). Put it back on for the 5th and last pull, ignored that feeling that I should go home (the spirit or intuition or whatever you want to call it).....and the car that was behind me when I got on the freeway was an alcohol task force guy. He said he couldn't pace me but when he caught up to me I was doing the speed limit or a bit under which was probably a good thing. I don't drink so I wasn't drunk so I think that made him happy. He might have thought I was drunk but I think I was too far ahead of him for him to see the car change lanes when I got out of the throttle (tires blew away 4th gear) and then went back to part throttle.
He said no Exhibition of Speed Ticket tonight but to "not do that again."
My roommate who was datalogging said a good rule of thumb would be: when there is an explosion (IC Hose, etc), go home.
So I guess the car is ready for Vegas.
I am really really really really happy about my fueling though. Replacing the fuel filter changed my 15:1 air fuel ratios into pegging the wideband at rich!
I feel sorry for my fuel pump. I sorta hate this car because I can't tune the car without being in 4th gear. I might have to relegate myself to the dyno now because thats cheaper then a ticket tuning on the freeway at 1 AM.
My roommate is not a car guy but he said that datalogging felt incredibly safe compared to what one of his friends with a race car showed him...aka driving really fast for long periods of time on Texas backroads and then slamming on the brakes just before hitting 5mph corners, etc. He said it was fun instead of scary.
Car is now doing 11.8-12.2 on the wideband at 21-22psi boost (on the 5th run).
I could try for more but I think this is a good place to stop. Its great to know what the fuel system problem was. I thought my Alky pump started leaking again but that wasn't the case.
I sorta want to hit the dyno now!
