Here ya go...

Sensor_______Average_______Min_______Max


Left O2______607_____4______977

Right O2_____447_____4______1008

Spark Advance______33_____0______47

Spark Retard______0.04______0______12

IAC______78______42_______116

MAP______38______13______101

AFGS_______26_____0_______250


Please tell me if any of these numbers look out of the ordinary, especially the spark advance (are these cars supposed to run that much timing), the IAC #'s, and the right bank O2s average much less than the left bank.


Also, is the right bank O2 the driver or passenger side?


Lastly, my car has a REAL bad hesitation right now, I don't know if it's bad plug wires or the new IAC I just put in the car today.

 

Static O2 readings are pretty much worthless, since they change many times per second.

Everything is is relative to RPM, speed, engine temp., etc., which you don't provide. Snapshots of data don't provide enough information to reach conclusions.

Right bank is the right side as you sit behind the steering wheel.

 

Why don't you just post a link to the DataMaster file? If you post it as a .csv file, anyone can open it and manipulate it with Excel. Or post it in .uni format and limit review to people with DM.

Your O2 sensors are supposed to average 450mV IN CLOSED LOOP. Did you eliminate any PE mode frames from the data before you took the average? If you averaged only closed loop frames, the problem is the left bank being so high, not the right bank being low.

Yes.... that much spark advance is possible in "cruise" conditions. But since we can't see what the other engine parameters were when that single data point occured, we can't tell if you were operating in conditions where it would be normal to see that much advance.

Obviously, 12deg of knock retard is a serious problem. Again, need to see what else was happening when it occured.

MAP and AFGS look normal, but again, the way you presented the data makes the individual min/max readings sort of meaningless.

 

I'd be happy to. Where should I post them up. Also, I am running on 56K internet here at the house. When I get to school tomorrow morning I will have high speed, give me a place to post up the link and I'll have all the info for you.

Did you tune this car? Stock tune? Is this for the 94' Z with some bolt ons? All of the issues have already been pointed out until you post up the log. Do you know of any reason why the car would be pulling 12* of timing? Are you running premium? Open headers? Exhaust rubbing/rattling? Running lean? Running hot?
