    Silverado WOT eq ratio commanded not changing

    I am tuning my maf wot and I have changed my pe eq ratio table to 1.12 to get my close to .88-89 lambda. However while logging I noticed that my eq ratio commanded number hasn?t changed. Still reading .877 as it did when my pe eq ratio table was set at 1.14. This is going to make the error math incorrect when moving from stoich to pe target ratio. Is this as simple as logging the wrong channel or am I approaching it incorrectly by trying to change the P/E ratio to what my desired number is and adjusting the maf to compensate?
