A couple clarifications about my configuration: I am running with a SW chip (not Autothority's). I have a LC-2 WBO2 which is giving me my AFR and sending the O2 signal to the DME.

I tried driving without the O2 signal disconnected--no significant change.

I tried varying the resistance of the pot on the Autothority--no impact on AFR.

But... When I jumpered the B & C terminals in the engine compartment, AFR was much better at idle (down from 20.0 to 16). This was with O2 sensor plugged in but idle switch not engaged (DME doesn't know @ idle). So, something is commanding the ICV to move causing AFR of 20.0.

When do I go lean? Either at idle, or decel or VERY light loads. Cruising around at 3,000 RPMs AFR is around 15.0, but going down a hill with just a squeeze of throttle it stabilizes at 20.0

I do have a another chip and a stock AFM that I can put in to see what happens. Although the chip is from "Road and Race Inc." and I am not aware of how good that setup is, but I'll put that in quickly and see what happens.
