    updated XDF.

    EDIT by EagleMark: Thanks Robert!

    This is awesome work and the XDF you would want to use for $A1.

    updated XDF, couple of small AE related changes:

    F104 is actually against coolant temp, not startup coolant temp

    added this desctiption to other two related tables;
    used during air/fuel timeout fueling modification

    Scaling Factor for AE Pulse Width Calc (KAEOPT)
    used for global changes to AE pulsewidth



    KAEOPT is what is used to determine the base PW for AE by taking the required fuel calculation(for normal injector pulses) and is multiplied by the scaling factor to create the base AE pulsewidth. bigger numbers = bigger AE pulses overall.
