That's what I'm shooting for. Trying to "tap" the housing seemed OK for a rough setting but I knew there had to be more.


Right now my AFS at rest gives me 0.8 VAC. When the O2 sensor kicks in and Lamda starts hunting, the RPM swing seem to increase. I'm hoping the getting the 0.7 VAC will calm this down some. With the ICV disconnected, the engine starts and runs in "limp-home" mode steady as a rock. So I'm accepting that the O2 system is fun****ing as advertised..
