    '15+ EQ Commanded Channels

    I noticed that the bank 1/2 EQ Commanded channels act differently on 2015+ Coyotes.

    On the older models, they represent the equivalence ratio that the PCM is seeking. But on the newer models, the short term fuel trims get baked in to the logged value.

    Example: the EQ goal is 1.00, the STFT is at +10%, logged EQ CMD is 0.90

    Is there another channel that acts more like the old version that I am missing?

    ill have to see what other channels are available on my list. wouldnt a simple user math parameter correct this though?

    and just to make sure im seeing what you are, this point in the log has commanded 0.02 leaner than the other bank, which translates to roughly 2.3% of 0.83

    Same idea.

    I just like having the actual target plotted next to measured. This lets you easily see where you have deviations.

    With these channels, instead of EQR targets, like they used to be, they are now truly "commanded EQR". So, all the STFT error gets lumped into that value and it's no longer a good reference.
