I just got my AutoTap and I'm trying to figure it out. I'm the only one local that has it so you guys are my resource. What fields should I be monitoring and what are "acceptable values" for those fields. Here is what I'm currently monitoring and a few values from my car. Any input in greatly appreciated.

Engine Speed
Vehicle Speed
02 Sensor B1S1- .905 - .910
02 Sensor B2S1- .905 - .910
LTerm Fuel Trim B1- -0.8 to -1.6
LTerm Fule Trim B2- -0.8 to -1.6
Knock Retard - 0 degrees
Ignition Timing Advance- Max 25 (Damn 02' Cam)
Coolant Temp - varies
Intake Air temp - varies
Throttle position angle- 100%

I would probably replace the two temperature values with MAF and MAP values, and possibly throw injector PW into the fray also.

It really depends on what you are trying to determine though - it's generally a good idea to keep the number of logged parameters down if at all possible.

Your O2's seem a little rich, but our O2 sensors aren't the most accurate.

Could be the GMS is making you rich. LTRIMs look good and no KR is good too.

I was looking at the wrong log for the .940 O2's. They were for my friends 96' Z. Since I got atap, I have friends coming out of the wood work! I have GMS SFC's, not the MAF. I've heard enough about the MAF that I'm staying away. I'll update the data in the first post. Any input is welcome.
