I am new to tuning. I have Tunercats software. My car smells very rich at idle. From looking at BLMs it appears to be lean at midrange RPMs. It's also pulling timing at higher RPMs due to knock counts.
Any help is appreciated.

When I opened the download, all I got was three columns of data including the record number and the time stamp.

 

Thanks Fred. I'll try again.

I don't think that worked either.

 

What are you using to data log?

 

I'm using Datamaster.

 

Datamaster produces a log file with a .uni extension. Anyone with Datamaster can open that. There is also an option to export the file with a .csv extension. Anyone with Excel can open that and manipulate it. You have to tell the system what fields (eg - RPM, MPH, O2 volts, etc.) you want in the file.

 

Thank you for your patience. I think I've got it this time.

Idle looks good as reported by the PCM, are you smelling exaust w/o cats, or looking at dirty plugs. No cats will stink at idle. !!!! However look at records 2892 to 3427 you were in BLM cell 16 (idle) for about 60 seconds. Right LT BLM of 140 says you are adding 8% fuel to right bank and right ST BLM (actual O2 reading) is about 130 that says PCM is correcting OK. If engine is actually rich on right then the O2 readings are incorrect and you could have a bad O2 adding fuel when it's not needed. If right is actually not rich then PCM is fixing a slight problem (vac leak, injector,exaust leak, etc) by adding fuel to get ST blm close to 128.
The only retard I see is when goosing throttle record #5824 TPS 100% 5400 RPM @ 25 MPH 7 degrees retard is the worst . Looks like noise as MAP is 52.8 Kpa (lo/no engine load). Also retard is on there one recording cycle, that's a very short duration, is you retard decay tuned up high. You could set max retard for 4-5* and that would lessen the impact. You are not getting any retard or knock during acceleration pulls, that's where real knock would show. Overall your log looks good I could not see anything that jumps out.

 

forgot to ask if your TB is it stock.. thinking split blm issues. Your IAC around 38 and TPS voltage around 0.6 is good, so does not look like idle air flow problems. But aftermarket TB's sometimes cause problems anyway.

 

What is the elevation where you live? Barometer is 86.7kPa, which would correspond to about 4,200-ft above sea level. (Checked Reno... that's how high it is).

I didn't see much beyond what bobdec already pointed out. The things that look normal include:
-MAP
-Coolant Temp
-system voltage
-MAF/AFGS
-TPS
-idle speed
-IAC - a bit high on counts, but should not cause any problem

Spark advance at idle looks a bit aggressive. Not stock, would appear to be part of the tune for the cam.

The right side LTFT is high, as Bob noted. But only in the idle and very low load cells.

The knock retard at record 5824 appears to be due to the sudden increase in knock counts, which appears to be the PCM's response to the throttle open at record 5821/5822. The injector pulse widths wee slow catching up, leaving the O2 sensors reading very lean. The PCM may have simply reacted to the combination of sudden throttle increase and slow pulse width increase by ramping up the knock counts and forcing the knock retard to protect the engine. Odd that there is no decay to the retard, indicating that it was not an actual knock that caused the retard.

I'd follow Bob's advice and look for a vacuum leak. When looking for the leak, it's something that only affects the passenger side, and very small. Maybe look for a bad injector o-ring on the manifold end of the injector.
