fuel cut question
fuel cut question
--------------------------------------------------------------------------------
I recently moved to Arkansas from Albuquerque. My car is running like crap now. I think it has to do with the denser air from the cold, and lower elevation, although, I know turbos don't mind elevation too much, at least not as much as N/A cars. In Albuquerque, I could run 21 psi. Out here, being alot cooler, I have to turn it down to 14 just to avoid fuel cut. I have:
Turbo-back exhaust
hardpipe from intercooler to throttlebody
injen CAI
MBC
Is there any way to fix this problem? Why can't I run stock psi? If i pull off my boost controller, will my car run stock psi? I don't have the stock vacuum lines, so I don't think the stock boost controller will get an accurate signal, since there is a pressure limiter of some sort in the stock fuel lines.
I know most of you will tell me to just get a tune. I have a SAFCII, i just need to get money so I can get it tuned. A friend said he can tune it with a wideband. Don't you need a program to log the data? Can I tune when I am hitting fuel cut?
Any help would be very appreciated. Please no flaming, and only respond if you have experience in this sort of thing.

Hi
No don't pull off the boost controler what ever you do, if you don't know how your system is setup, you could be runnning your engine with no boost contro, at all.
I'd also strongly sugest you set your SAFCII back to stock settings ( no adjustment ) and get your freind to check your AFRs with the wideband, as soon as he can.
Have a look at the ECUflash forum on here, you will find lots of usful information there.
Don't run your car hard with constant boost cuts, you need to find out why it is hitting high enough boost to cut.
