RE: SAFC II
I cant remember what your GSX has.. Its a 14b turbo with what size injectors?
What do you have your lo and high throttle position set at?

RE: SAFC II
and your getting fuel cut at 15lbs? You should be up around 18-20 before you start to get fuel cut..

Oh yea myLow / Highthrottle points are 30 / 80
i have a very very small boost leak at the TB shaft seal, not enough you can even hear it leak, it makes bubbles really slowly, and it dontstart bubblingtill 20 Psi. Im getting fuel cut when i turn the fuel up past +19% on the AFC, my MAF is going absolutely crazy past 5500 rpm and the ECU is seeing 1900htz at the most. Thats right where it starts to run good(in the range of 11:1 a/f ratio)then it wants to cut on me.
when it cuts its not always the brick wall slam you get, its really mild sometimes but when it does it theres a drastic drop in Htz down to 300 or 400 sometimes. Thats why i took the honecombs out of the bottom half, but it didnt really help it much. I think im just over running the MAf or its just junk. the graph scale is jittery up & down then the higher it revs the more drastic it gets untill its jumping from 1900 to 300 back and forth. looks like a 4 year old scribbling with a marker on the graph scale. My peak Htz was 1938.
I have some 560cc injectors ic an put in but the MAF is still going nuts. i may have to let more unmetered air past it so it quits.

RE: SAFC II
I made a deal similar to what you see people selling to hook up on the inlet of the turbo. then i started turning up my air regulator untill i got 20psi on my boost guage with the throttle plate open. I hosed it down with soapy water, found a few small leaks and fixed them. the TB shaft seal is like a slow leaking tire, it take almost 30 seconds to even make a bubble. Even if i open or close the throttle. to worry about one that tiny is gettin too picky for me.

RE: SAFC II
Ill be starting over with the GSX, i got a 255LPH fuel pump, AFPR 1:1 rise rate, and gonna put my 550cc injectors in. and switch over to a 2G MAF.
and the 16g. its an EvoIII, i thought it was a big 16g.
45 Psi base fuel pressure a good place to start? since the exhaust fell off tonight after bashing it down an oil well road i might as well bend up some 3" pipe for it.
its gonna be so fun to stomp the **** out of some ricers in a rusty ugly *** car.
Rust is less weight - makes it faster lol
i'm just gonna have fun with it untill it dies then probly sell some of the parts and keep all the drivetrain for my talon.
