I know, it seems completely opposite to what I have also read throughout this forum. BUT turning the mixture adjustment to the right (counter clockwise) results in lower % duty cycle reading on my car. Any thoughts? The only thing that crosses my mind is the cars attempts to compensate for the lean mixture but adding fuel through the EHA.

I had the car adjusted to the factory specified 50% duty cycle and near 0 ma at the EHA prior to its biannual smog check. It failed and they LEANED it out. I checked the duty cycle when I got it home and it was near 20%. Go figure. Completely inverse to what one would expect.

Look at the graph you just posted. 78% is on the left side of the graph, the rich side. Am I reading that right???
