What else is needed?
Going to purchase the dashlogic unit just want to know if I need to buy anything else to run it correctly. I am mainly concerned with getting the readings for boost, fuel pressure and air to fuel ratio. Do I also need to purchase a PLX SM-AFR device and a 3 bar map sensor to get the readings I want?

Another thing to keep in mind: The dashlogic only has 2 external inputs, so if you want to monitor A/F, Boost, and fuel pressure, you need to use a map sensor that is being monitored by the ecu so you still have the 2 inputs for A/F and fuel pressure.

Could also wire FP to the ecu to free one up if needed, or AFR.
He pretty much covered it. Need a wideband for AFR, need a FP sensor for FP, and you should have a map sensor that can read to the ECU. That should have been part of the SC kit and tuning before, but some people don't so you may need that if you want boost.

Yep! Do boost by replacing stock sensor.. then AFR/fuel pressure via external inputs

You can use the wire a 0-5V sensor into one of the aux inputs on the ecu and monitor that trick too. Look up monitoring AFR on HP tuners without the proversion. I forget what pin you wire into, but you can look at that for another input.

I've seen that you can do it through the AC pressure input, but it seems like you could use the EGR input (not actually used on C6's) and do it that way too, and not lose AC in the meantime
