    I am not aware there is such a table. You control open loop at wot by controlling pe. When pe is entered, you are in open loop. LTFT may still be active at wot, depending on your level of mods most just disable LTFT.

    Why do most people disable LTFT? Seems like it would be a good idea to leave it so that the engine could adjust as needed.

    narrow bands cannot accurately determine fuel at anything other then stoich. You may have your tables dialed in at WOT, but LTFT drifts around. Disabling LTFT eliminates this.
