Can someone check out these logs?
 

Hey guys! I just wanted to say that I've been using the JBR Power Path S-OTS maps for a few months now, and I love it.

Can I get someone to look @ these two logs and possibly tell me what's causing these symptoms.

The first log I took while sitting on HWY 2 in AB this afternoon, numerous collisions resulted in a 2 hour delay for my drive home. While waiting for emergency crews to do their thing, I noticed that my idle would drop below 700RPM. This is in either neutral or gear w/ clutch in. A/C off.

The second log I took on the highway, I noticed once I let off the gas that RPMs wouldn't drop right away. I assume this is an issue with the BPV (OEM). (Row 25-32 shows the RPM stuttering after lifting off)

Let me know if you want me to trim the datalogs... I pretty much logged every parameter possible.

PS it was -15 to -20 C.

Thanks!

Firstly, you dont need to log so many parameters. The more parameters you have the less data will be recorded per second per parameter so keep that in mind.

As for the wonky idle, check your entire intake and BPV to make sure there are no leaks. A boost leak can result in fluctuating. I completely forgot to reattach my recirc hose (lol) on my BPV after installing my downpipe and had the same problem so give that a check.

Not sure what you mean by your RPM stuttering. Unless you push the clutch in right away after lifting off the accelerator, the RPMs aren't just going to drop drastically in an instant.

Hope some of that helps.

I agree with the possible leak, or you may just need to do a MAF cal. Probably the leak, but your LTFTs are a little higher that most people like

For the first log the thing that jumps out at me is the AFRs being stuck at 14.85 for long periods of time. This can mean the wideband sensor is on its way out. I would keep an eye on this.

The second one is likely the car trying to light off/warm up the catalytic converter. This is a practice where fuel continues to be delivered for some time after you let off. This is associated with the cold weather most likely.

The fuel trims are a little positive but nothing that says big leak to me. The very cold air could increase the fuel trims a little bit.

Alright, thanks for taking a look at these logs. The car drives fine and never hits any cuts. I can't do a MAF cal since the ots maps from stratified are locked. AFRs usually jump around, I'm not sure why they were pegged at 14.85. I'll check for a leak and watch the wideband sensor.
