calibrating plx wideband

i am having trouble getting my plx wideband calibrated to the gauge. the car idles pretty rich and if the gauge is sitting still(around 10.5) i can get it pretty close.once the gauge starts t move around, they aren't close anymore.my question is how close should they be? it seems like the reading on the hondata wants to bounce around until it gets in the 10's once it gets down there,it tries to stay in one spot, usually around 10.5.i leaned it out at idle because it was so rich and when i initially set it, it was close, but once the gauge started moving the hodata wasn't close anymore.i hope my decription makes sense.this is very frustrating

WHere are you getting power and ground for the PLX?

power comes fromthe ignition switch and ground for the plx and it's capacitor are grounded to bare metal on the firewall above the ecu.
hey, i am using d10 for input.i just read where i may need to remove r136 and r138. could this be causing it? if so,should i just use the o2 sensor input? i have it disabled anyway

It should be wired exactly as it states in the above instructions.
