Need help setting up Aquamist to run based on boost alone

[BMC123]

It appears there are discrepancies between my user manual for the HFS4-v3.1 and the downloadable version on this site (pg. 14, under TRIG, there's no mention of the P+I jumper link). There is an extra TRIG jumper-link slot on my system board (it's called the P+I trigger) for boost and IDC combined. I'm guessing that was removed on later iterations of the system as it looks like the same results could be achieved with the P/I-R trimmer. Not sure.

Anyway, does anyone know if it matters to the P/I-R trimmer, which TRIG you've selected (MPS or IDC)? Also, on the bottom of pg.13 of the manual, in describing the LED panel, it references the RED (95% DC) but the diagram at the top left of the page shows the RED LED indicating 95% IDC. One appears to reference the injector duty cycle of the fuel system and the other seems to be referencing the duty cycle of the Aquamist. Thoughts?
