Any of you afc hack users having any problems? Seems my ecu keeps seeing boost even tho my settings are at most -30%
My cel keeps on coming on. DOH! any suggestions?

genop

how much boost are you trying to push??

yes, -30 is too much, shouldn't go below -35%

i'm only pushing .45 bar or 7 psi. i'm using 370 cc injectors. my idle fuel pressure is at 43 psi. It never did it before... just started...

help!!! i can't stand this stupid cel... everytime it goes on, the car goes into limp mode. driving around in limp mode sucks. the car seems to over heat really quickly.

Well, everytime I've read about the S/V-AFC "hack" it's said to use a set of 440 or 450cc injectors, so that may be your problem. Read this page about it if you haven't already: http://www.thedropshop.tv/vafc.htm

ive been getting the same problems lately, to temporarly fix my problem i ran one check valve to the map sensor and it runs alot better, so im getting another map sensor to see if that fully fixes my problem

you need bigger injectors, because -30% won't cut it, you can't run that rich, you need to be at no lower the -35% and then you won't throw a CEL. invest in some bigger injectors...once your run the car where you don't have to have to go below -35% then your set. 450cc or 440cc will do the trick. if you set the car w/ -35% right now, you won't throw a CEL, BUT you may be running to lean running w/ the 370cc's

Yep, I tried with 310's at -30% and got a CEL everytime I went over like 5 PSI.

yea get some bigger injectors... 450cc is what seems to work best with the afc hack.

does anyone know if dsm 390cc injectors will work?

You can drop the vafc down to -35%, and then increase your fuel pressure a bit to add a little fuel back. b
