I see this is your first post but you gotta give way more information if you expect to get any help.

Lets start with some basics like what car do you have, how many miles, any modifications? When did the problem start, etc...

It鈥檚 a 2015 civic si coupe with about 49401 miles it has a skunk 2 cai , cnt racing catless down pipe 3inch and a invidia q300 . The code first popped up a week after I bought the car September 2020 the car came with the exhaust and cai and months after the cats clogged up and now I鈥檓 catless I also have a ktuner v1.2 with the base tune they have im thinking I need a proper tune but since it鈥檚 running too rich I鈥檓 thinking it could be an underlying issue

You have a base tune. You just figured out your problem.
Like @TenZen said you're on a basemap. Those maps will just help you out until you get a real tune.

The main purpose of any tuning program is to allow for changes to the fuel and ignition maps. This is 100% your issue.

Okay my peeps I went ahead and reached out to a well known etuner that goes by yosh he鈥檚 been confused by why my car is running so rich and was amazed by how much fuel he was deducting , my car started to misfire in vtec and it was all of them at one point so I took it to a mechanic and he found out that it was a due to a exhaust manifold leak I had some bolts loose and one missing 馃う馃従鈥嶁檪锔
