Ok so first off i have stock injectors for now until I get the hang of link. The o2 sensor is brand new and is not cycling, also my wideband is off the gauge lean. It was holding 12.3 for a while but then disappeared.

I read that the TPS has a large effect on the o2 sensor, do I need to change anything with this?

Also I see on my DTC the oxygen sensor is incomplete, what does this mean?

Are my mafRaw and combinedFT too high?

Lastly the wideband sensor was extremely lean (off the gauge) would this be because it was after the flex section in the exhaust? As mentioned its a brand new exhaust, no leaks.


Mods:
v2.5 \\ 1g head \\ 264-272 cams \\ 2g 7bolt \\ 97cas \\ ported 16g \\ pte 880s \\ dsmlink v2.5 \\ wally 190 rewired \\ ported 2g manifold \\ ported o2 \\ full 3" exhaust \\ ported 16g

Try logging your wideband, tps, tpsvolts and iscposition.

And get a volt meter and check your "new" sensor its possible to get a bad one.
 
o2 sensor looks good.

Your tps is off by .02 volts though.

Readjust your tps and log your iscpostion so you can adjust your idle down closer to your target idle.
