My understanding is that to use ABW / 3K printing you "let printer control color" (by means of
the ABW adjustments). Thus, there seems to be no possibility for using "color profiles" via
Printfix Pro to tweak the 3K black and white printing.
You have two choices for gallery quality B&W or tinted B&W prints with Espon "two gray ink" printers. The first is to use the extended grays target in addition to a color target, build a color profile, and print through that profile and the color mode, to get great B&W output (and great color output from the same workflow and the same profile).
The second method is to print the 225 patch target (and later, the extended grays as well, if you wish) through the AWB mode, and build a gray linearization profile. This type of profile is not as flexible as a full color profile, and should only be used with the EXACT same AWB settings as the target(s) were printed through. It will not allow tint or neutrality adjustment (that is being left to AWB, and needs to be determined BEFORE building your profile), but will create smooth, accurate linearity in your B&W prints. It will also provide a profile for softproof previewing in Photoshop, to do your final image adjustments.
Please keep in mind that gray mode profiles such as this take much longer to calculate than color profiles. When the "build profile" step is reached, leave your computer, have a cup of coffee, and don't panic if its still working when you get back. Do not assume it has frozen, just let it run its course and it should produce the profile you are looking for.
