It's not that easy I'm afraid. CCW on the EHA screw will lean you out but then you have to go CW on the idle/CO screw. You really need to see your A/F ratio to understand how the computer is working, or not.

Once in the range the computer will keep you near 14.7 (in closed loop)until you continue your adjustments out of the range it can handle. That range is about 1/2 a turn on the EHA and a bit more on the idle/CO...again, in my single case.

You can try 1/4 turn CCW on the EHA screw and 1/4 to 1/2 CW on the idle/CO screw and see what happens or if you want to contact me about using the wideband give me a call through the website...appliedracingtechnology dot com
