Using a scan tool one would see a more accurate AFR at the primary lambda sensor. All installs are logged and checked to validate target lambda meets request.
Okay. Excuse my ignorance, so the computer continually adjusts, at WOT, to ~12.32? Or, am I taking your statement out of context?
Obviously, the DME must be tuned pretty close because I'd think that the O2 sensor can only adjust the fuel trims so much.
To OP, congratulations.
