Hello everyone, I need some help reading my data, seems to me I have a rich condition.

My car was running very poorly last year and I traced it a plugged/broken up catalytic converter. I have since replaced the converter, and decided to reset my TT chip and relearn.

My combo is:
212/212 cam
Te60 / 63a/r turbo
FMIC
42.5# injectors
TT chip 5.7 93 octane
autometer narrow band a/f gauge (I know I need a wideband)
autometer vacuum/boost gauge
Data aquisition using TunerProRT software

here is my data:

Key on, engine off:
TPS: .41
IAC: 140
ECT: 54.50*
MPH: 0
LV8: 0
RPM: 0
INT: 128
O2 mv: 501.72
BML: 128
O2 cc: 0
Spark Adv: 0
MAF: 4
IAT: 114.80*

Key on, engine running cold:
TPS: .41
IAC: 175
ECT: 55.85*
MPH: 0
LV8: 108
RPM: 975
INT: 128
O2 mv: 515.24
BML: 128
O2 cc: 50-235
Spark Adv: 0
MAF: 17-18
IAT: 147.56*

Key on, engine warm:
TPS: .41
IAC: 83
ECT: 178.35*
MPH: 0
LV8: 47
RPM: 875
INT: 128
O2 mv: 1047.84 (WHAT???)
BML: 118
O2 cc: 5
Spark Adv: 0
MAF: 6-7
IAT: 137.40*

Key on, engine running after 15min test drive:
TPS: .41
IAC: 51
ECT: 176.00*
MPH: 0
LV8: 42
RPM: 825
INT: 128
O2 mv: 890-905
BML: 118
O2 cc: 5
Spark Adv: 0
MAF: 6
IAT: 137.52*

At idle my vacuum gauge reads approx 17"hg,
My TPS reading on TunerProRT shows .41v at idle, 4.12v WOT.

Any tips or help would be great!

Thanks!
