    Has the issue with E38 02 switch point issue been resolved?

    Did some research on these forums and it looked like the minimum value setting was supposed to fix the issue, but I'm still seeing no change in my CL air fuel by lowering the switch points.

    So for once I decided to monitor my wideband and NOT logs. My wideband is actually going over 14.5 which it would never do until I made this switch point change. I will be a little more aggressive with it.

    Are you changing the "min rich/lean" setting and then going into the Bank 1 and Bank 2 O2 Rich/Lean Vs. Airflow tables?

    My stock LS3 tune (E38) has both the min and max set to 450 mV and both of those tables (bank 1 and 2) are both sitting right at 450 mV. I'm going to play with this soon...right after I get my VE stuff dialed back in for the new heads/cam/intake...so I'm curious what your results are.

    Correct, in order to get the lower mv to function, you have to lower the min table. It is certainly working for me. Yours sounds setup exactly like mine with everything at 450mv.

    I set my mv to 375 for all but the last two airflow modes in which I put it at 400mv to richen it up a little. Did logging this morning and I'm certainly getting leaner than stoich when cruising around, no knock, and the truck is running good.

    Sweet, once I turn closed loop back on I'll play with it too.
