Default LM programmer voltages

Alright, i know there are a ton of lc-1 install and setup threads already, and ive read through all of them and i've just gotten more confused.

My setup is pretty stock right now, just getting the lc-1 working before going turbo. I installed it the other day, and was getting reasonable readings, just the numbers between the db gauge and mspnp were off by about three. I do have the grounds together on the same lug on the ecu ground. My analog 1 (yellow) is to the ms and my Analog 2 (brown) is to the gauge. I hooked it up through pin 10 of the mspnp. i tried messing with the programmer to fix the discrepancy, but now my gauge is all messed up and i cant get it to read any sensible numbers. what are the voltages supposed to be in lm programmer? what ive found is 0-5 v and 10-20 afr for the ms, but idk for the gauge.
