Fuel actual not following fuel cmd

Post by Awsomsauce »

All of my fuel is not meeting what’s being commanded on the tables. My WOT and lean best torque tables are commanding 11.18 afr targets and my car is absolutely set against reaching that goal. It hits 11.7-11.8 and that’s it. I have an aem wideband sensor installed in the second o2 bung on the down pipe and the gauge reads .80 lambda even though my tables are commanding way more. What’s happening? I can send the tune and log but I’m not posting them here in the forum.
It doesn’t matter what the ethanol content level is in the car it refuses to hit my target.

Wild guess, AFM calibration is off.
