Full Throttle=Lean????

[b11dragone]

I have been having problems with my car for about 2 months now. When I installed my exhuast,intake, bov, intercoolerpiping, my car started to run like shit at wide open throttle. Didn't know what was going on till now because I just installed my air/fuel gauge and afc II. When I drive normal my gauge reads stoich like it is supposed to. If I push down my throttle 25% it goes to rich and runs stronger than if I push the throttle down 100%. When I do push the throttle down 100% my gauge reads lean, and my afc II reads that there is alot of knock. I know this is bad, but what is causing it and how do i fix it? I haven't messed with the settings on the afc II and this was happening before i installed it so it isn't that. I am just using it to monitor what is going on. If you have any ideas what is causing this problem or what can be done to fix it please let me know.

your afc can read knock on your car?

yeah..you have to set the correct knock when you first initialize the afc...then when the knock is over that set limit it lets you know

The AFC II can read knock. Just to clarify

i know the afcII can read knock but i didnt think the 2nd gen cars had knock sensors, i have the afcII can you explain to me how you got it to read knock because i was told it couldnt, thanks

its in the diagram from apexi...it labels the knock sensor on our ecu..just attach the wire and your set
