Problem with O2 reading on F/IC

Has anyone had any problems with their F/IC picking up the O2 signal? I spliced in my harness and have had great luck with it. I have never messed with the O2 table until recently though. I discovered that I am getting no reading from the O2 wire.
I double checked my connection and I tapped into the correct wire and the solder connection is good. Has anyone had any similar problem getting a reading from this wire or does anyone have any suggestions on what is going on? Thanks.

I do but I think that sometimes even with my good tune that I run a little rich (tuner being safe) .... I know that everyone likes to get gas at the same place each time but sometimes you cant... try it and see if it comes back on... your o2 sensor might be dead... I know one of mine died kinda early in my cars life... just saying
Hey bud how are ya? Anyways do you mean the fic does show a voltage or when u measure the wire with a dmm it doesnt show a voltage? In order to do the 02 correction on the fic you have to use a voltage mode which allows you to enter raw voltrage into the 02 map - when you do this for some reason the 02 bank data will show 0 all the time but it is working, our cars 02 sensor varies the amount of current to create a reading rather than voltage like most so by providing a diff voltage from the fic it can lower and raise what the ecu believes is stoich, if u meter the wire with a dmm you should see a nominal voltage and everything should be fine dunno y the fic does show the voltage on the 02 sensor when its set to a pure voltage map mode.
