Im in need of help very badly ! Question about Vafc Hack
my prob: taking all my turbo stuff off my car and running all motor for a while, but I deceded to leave the DSM 440's and injector box in and just controlling the fuel with the Vafc. But, I'm not sure where to put all my fuel settings at. Since they are 440's if I set the correction at 0 (or stock setting) they will be pumping too much fuel into the motor, so I would want to lean it out some right? If that is correct how much should I lean it out? I know that you can't just "pick" a number and set it, it has to be set accordingly but I need a round about number so from there I can play with it. Any help would be GREATLY appreciated thanks

set it to -35 across the board - then you can mess with it from there

Re: Im in need of help very badly ! Question about Vafc Hack (Atheist)
I thought that since stock injectors are 240's, and now he's got 440's, 240/440 = .55 so wouldn't he need to set it at about -45? Isn't that about right or did I miss something somewhere?

when you make me that chip bastard!
just to update, i've been driving it at -35 across the board, but in frist gear around 4-5000 rpm the car really feels like it's bogging out bad, and every where else is good what should i do about the first gear thing?
thanks
