okay, this is wierd.
i run perfect A/F ratios when I first start up the car and go boosting, but after about 35-40 seconds, it really runs lean under boost.
what the heck ?? i think the computer when it warms up, it thinks that it should run lean for some reason. I don't know why though... you would think the computer would run richer if there was any problems....
anyone have any ideas?

Re: wierd new lean problem.... again :)
ya lol, I am getting a MSnS soon(week), but for now, I use an FMU(vortech), which some people seem to be having good luck with.

Re: wierd new lean problem.... again :)
Thats why your leaning out. Your stock ECU has no idea your running boost. The FMU is not enough to add the required fuel for 7 psi; not even close. There are some calculations you could do to determine how much fuel you need. You'd probably find that its more than the injectors your running can physically handle.
Dont tell me your running stock fuel injctors as well???
Did you get a copy of Corky Bell book?

Re: wierd new lean problem.... again :)
some people here had plenty of success(andy,antwan, and others) with the fmu setup. and yes. I upgraded my injectors, and I have read corky bell's bookEZ_4_FUN wrote:Thats why your leaning out.
