Hey Civicx members,
I've been having an active thread relating to a load of issues I've been having related to running rich. Please see this topic on pages 7 and 8 to basically see what whats been going on. https://www.civicx.com/threads/product-advisory-all-16-18-1-5l-turbos.38962/page-7
To keep this as short as possible with the above topic reference, I was running extremely rich to the point it maxed out the STFT and LTFT values and caused the P0172 code. There is a recall letter for this so I thought it was related to that. I flashed to stock and the issue still seemed to be present. I ended up removing my PRL catted downpipe, front pipe, and AFE intake, put all the stock parts on, then flashed back to stock in preparation to take the car in for warranty service. The only thing left on the car was the 3" catback with muffler/resonator deletes.
After removing those parts my fuel trim issues appear to have disappeared (STFT spikes occasionally to -10 for a short second but is usually -1 to -4, same thing for LTFT). My PRL catted downpipe was damaged (if I shook the pipe, the catalyst material inside would slide back and forth and it was flaking inside the pipe). I don't know if that could've been the cause of my issues. In any case I messaged PRL about this and they said it was a known problem with some of the v1 pipes from the earlier batches that shipped last year, and they are sending me a v2 catted downpipe free under warranty.
I was suggested by some users to post my tune files from my custom dyno tune to see if the tuner messed something up and caused permanent damage to my car. At this point I need to find out where the problem lies so, it's obviously with the downpipe, front pipe, intake, or tune. If there's anything wrong with the tune files please let me know, as I would need some concrete examples to confront my tuner if that's the case.
Here is a link to the tune files. The first one is the original, the second one is some revisions he sent me via email afterwards to correct idle and other things like disabling some codes, and changing something related to "mafscale"
