Installed intake and got a code. HELP!

[razorlab]

would it be lambda 1 AFR? I did a mini log and it says 14.7. And my boost was 9.2 max. Won’t go above that.

Can you share your log?

Yes I did use that metal coupling and it seems a little loose! I did use the OEM orange gasket too. That person in the thread said he stopped using the metal coupling and instead put the silicone inlet directly on. Do you think I should do that? And just get rid of the metal one?

That is what I did, even though it felt wrong lol. Now it connects perfectly and the crank case breather connection has enough slack to actually connect. I still feel like something is wrong but it’s been fine.
Anyway, it still likely doesn’t explain your code

Thank you brother I will try this. It kinda makes sense to me that the code would be from that though. Boost leak = more air in the system? Thus making it more lean? Idk we’ll see I hope it fixes it. Gonna reinstall it tomorrow afternoon I’ll update everyone

Good idea to try installing the intake without the metal piece, though for the code I would still send a log to Razorlab, if he’s willing to look at it, has far more experience.

Boost leak would traditionally cause it to run rich. The intake pre-turbo is under vacuum, not positive pressure.

Fuel trims are labeled LTFT and STFT. Long Term Fuel Trim, Short Term Fuel Trim. STFT is instant +/- fuel. LTFT is learned over time so STFT doesn't have to do as heavy lifting.

I don’t have LTFT maybe because I just reflashed the car. But the STFT was 4.31. Not able to upload the log here I guess because I’m on my phone. Will try later when I get off work

It’s just weird because I installed the catless downpipe myself 2 weeks ago. Made sure all connections and sensors were right. Had no issue. And then few days ago I installed the intake and had an issue right after doing so. So I would think the intake is the issue.

Intake isn't related to lean codes. It sounds like a coincidence

Does this link work for you?

I got in my car and drove home after work. The first 10 minutes everything was great worked like normal even hit 21+ psi. And then out of nowhere it went into almost a limp mode and can’t pass 9psi. So I guess the intake isn’t the issue since it worked fine the first 10 minutes. Damn I have no idea what’s going on. So the downpipe was installed incorrectly? Or what.

Here is 2 more logs I just took. Car is driving fine today. I’m very confused

Beginning of my drive this was my Ltft and stft but then later on the ltft went up a bit. I think 15 at idle

 

[maserati]

Could this be due to a leak? I’m not 100% positive I pushed the exhaust all the way into the downpipe. It wouldn’t budge anymore so idk it was in a good amount. And I don’t see any visible soot by any connections

Car is running a ton of timing correction. Try the 91 octane map and see how it behaves

What can be the cause of this? I get 93 gas from Shell.

I will reflash stage 2 91 and take another log. What should I do when logging? Normal drive and then 1 WOT pull in third gear?
