Anybody good at diagnosing data logs??

Spark plug gap? Mines gapped at like .032 or .036 can't really remember

Your running n2o correct? If so, the .032-.036 gap would be correct for a FI car.

Im on a stock tune at the moment. Im sure even if I gapped the stock plugs down to .028 on a stock tune it wouldn't idle as bad as its doing right now.

Im thinking about just buying a set of o2's and seeing if it changes anything.

When my o2's went in my 2012 gt500, when I data logged the car and looked at the measured AFR Bank 1 and 2 pid, you would see neither would report. Good way to tell.

Mine are doing the exact same thing.

ST and LT measure voltage but the AFR Bank 1 and 2 read "NAH" or "N/A" or something like that

Then theyre dead. You didn't happen to of extend them did you? By cutting/splicing more wire?

Nope. Never touched the fronts.

Im sure when it was running rich as hell from the oil being pushed through the compressor seal of the turbo, it fubared the o2's

Jay, wanna take a look at my data log to confirm I have the same readings you got before I buy a set of o2's from rock auto?

sure.

Are you throwing a code? When mine died, it actually gave me a stuck o2 code, saying the car was biased towards lean. So naturally the computer started jamming a ton of fuel so it would be pig rich and soil up my tips.

 

[WILECYOT]

print logs to picture and post up already.

 

[slvr08gt]

sure.

Not a single code. Thats the part thats most frustrating.

Shoot me a PM with your email addy and I'll send you the log.

Then it hasn't tripped them yet, mine took a few days to throw a code.

I should have done that in the first place but im at work now.

Your front o2's are getting power but they are not reading/reporting. According to your logs. The sensor is most likely fouled.

Well I guess I'll place the order for the new pair o2's then. Is my log the same as your log read for those PID's?

No, mine were not getting voltage. Mine was a wiring issue.

Hmmmm. Well im uber confused now. Not reading or reporting on AFR bank 1 and 2 but they read voltage on ST and LT's.

Go back up and reread what I wrote. It looks to be like you have a sensor issue, either its clogged or damaged.

Mine were damaged at the wire, hence they werent getting power.

Yea I'm on the bottle but I leave them at that gap off of it as well when driving on the street

I and others have had issues with failing o2's running e85. The OP symptoms match. Last track visit I had a driver side o2 crap the bed and it took some time for the CEL to trigger. That is why I asked about running e85.

I'll have to keep an eye out then. That's the first I've heard of it.

I have a copy of the datalog and I'll post a screen shot in a little bit. AFR doesn't report but lambase does. I was guessing that lambase was the actual lambda. That part is reporting close to 1 with a little wavering. LT stay the same but ST fluctuate just like normal. I will say I'm not familiar with the copperhead platform but seeing those move around makes me think the o2 sensors are fine.

 

[BruceH]

OK copperhead folks. Here it is. The afrs switch from 0 to NaN.

as I said before, the front widebands are not reporting. Most likely the sensor in itself is damaged.

What's the lambse? It must not be afr in lambda like I thought.
