Default F.A.T.'s "piggyback ECU"

I am planning on a FAT Stage 1 w/ my own FMIC setup, but I am wondering what is that little piggyback unit they say controls timing? Since I can't seem to get any answer when I call them, I ask you all. Is it tunable? Is it plug in or splice into the ECU harness? Looks like splice in from the photos. Anyone with any input would be nice.

It splice's into the coil harness it has a knob that allows you to adjust how many degrees of timing to retard per psi of boost. Forced Air moved so they have a new phone number It's on the website www.forcedairtech.com
