CEL - P112F - AA Catted Downpipe

[JRedMKV]

Hi guys, I installed the AA catted downpipe about a week ago and have driven about 150 miles. All was good until yesterday when I got a CEL. I used an OBDLINK MX today to check the code and got the P112F code. I also checked if my JB4 had any codes and you can see a bunch of them in the pics. I was able to use the JB4 to clear some of the codes but a few still remained but the CEL light turned off. I also turned the JB4 back down to the stock Map but I was only on Map1. I did not check if the P112F code was still there that the OBDLINK read. Do you guys know if the downpipe caused the CEL and should I be worried about this issue?

Just installed AA catted downpipe too on my 2020 and got a CEL. Though your error is different it seems. Not tuned yet.

Check all your wiring on the JB4. Set the JB4 to map 1.
check that your CAI and inlet are tight.
delete the codes and let the car idle for a few minutes.
run a log and share it with us or BMS

I was too worried to run it on Map 1 but I did do a Map 0 pull after checking everything like you suggested. Everything looked good under the hood. Couldn’t hear any leaking or anything weird. Drove it around for about 30 minutes and it felt really good. Apparently I can’t post a .csv file here unless you know how to do that or convert it?

Did you clear the code and see if it would pop back up?

I need to plug the OBDLINK back in to see if the code is still there but so far the CEL light has not popped back on.

What mods are on your car?

What mods are on your car?

I have an Armaspeed CAI, Injen charge piping, the JB4 and the AA catted downpipe. Before the CEL popped up I was just running Map1 and everything was fine for about 150 miles after adding the downpipe.

Just received my AA catted dp but this thread giving me second thoughts on having it installed. Hope you get the CEL resolved

Well the CEL came back yesterday. Same P112F code. I have noticed a few weird things lately even before the code popped back on. First, when in Comfort Mode, the car feels really sluggish trying to accelerate. If I put it in Sport Mode it seems to accelerate fine. It has been about 100 degrees here though so I don’t know if it’s just the heat. Also, on the JB4, it seems like I’m not getting a reading on the IAT gauge. I swear I used to. Do you guys get a reading there?

Here are a few screenshots of the JB4 showing no reading after driving it for about 30 minutes. The other screenshots are the readings I’m getting from the OBDLINK MX.

I am now back to stock settings again on the JB4 and cleared the code. I’ll probably put the stock downpipe back on next weekend and see how it goes.

Same here

No need to worry. I have an AA catted downpipe and no cel. Have had it on for a couple months and a few track days. Make sure to install it properly and before you just take off, I try and let the car idle for a min or so before leaving. I loved it so much, I went with their full exhaust as well!

Wanted to second this. I have an AA catted downpipe and have been running it for maybe about 1k miles along with a JB+ (not JB4). No CEL or any other weirdness - works great.

I have had my AA downpipe for the last 8 months with no issues. Ran without Ecutek for half of that time with no issues.

So what was the conclusion here?
