Adding an INPUT to URD Performance Calibration Unit?

Hey guys, first real post on here, have a question, curious if anyone has any input.

To start, I drive a 4Runner (Gross, I know) supercharged, URD 7th, TRD Exhaust, all sorts of fancy stuff.

Early on in my "wtf, why won't this thing run correctly" stage (prior to the 7th injector install, which is golden) I consulted Split Second about their FTC1, which is incredibly similar to the URD Performance Calibration Unit.

Their FTC1 came with an option to add 4 aux inputs for like $75. Essentially just added 4 wires to the harness of the FTC1, so that you could data log instead of just psi/rpm, things like egt, A/F, etc.

I think that the ability to add an input for A/F would be VERY helpful for us home tuners. To be able to log boost/engine speed/AF all in one using just the Split Second R4 software.

My question... Have any of you wiring/electrical experts looked into this at all? Thoughts on if it's possible or no?
