Because people can't use Stage 2 without the supporting mods (DPs).

Stage 1+ is for those who have upgraded to an aftermarket FMIC. I think the one stage that isn't really all that necessary is actually Stage 2. I always recommend FMIC before DP and I don't see why someone would not get an FMIC lol.

I have DP's and no FMIC lol

FMIC are stupidly expensive (as are DP's).

Not if you know where to look. You won't see me spending anywhere near 800 for a set of downpipes. There are also budget FMICs out there that are quite efficient.

I've got these codes
P2AAF - fuel pump plausibilty
P2C7F - Lambda probe after catalytic converter 2, trimming control
P2DED - Power management: quiescent current violation

I'm running stage 2 + fmic drive with 91 oct. Are these codes normal? I'm getting SES permanent light.

Delete all codes, reset ECU and drive , if you get them again you definetely have an issue and you should mail cobb for support.

Do u have a BMS dp fix installed? If not one of your rear o2 sensors are toast it seems.

No I dont have BMS dps fix. So Cobb AP doesnt fix DPs cell? Why is the O2 toast?

yes it does fix it but your issue is not related to downpipes. you are getting an 02 sensor code . Its an hardware issue.

First code is when lpfp can't keep up with req value, no big deal, the second code is because an o2 sensor in the rear isnt doing what it should, and the third code is battery drain related, you likely kept your Cobb ap plugged in for an extended period of time with the car not running. That's as detailed as I can get on a phone.

i didnt get this code before the catless dps installed, so this is imlying that the catless dps killed the O2 sensor?

It's possible the sensor was damaged during the install or they incorrectly installed the sensor to the wrong downpipe.

+ 1, if this started happening right after dp install there is a huge chance thats the cause. Are you 100 percent sure you are running stage 2? dumb question but you never know :-)

I have the same code. It's a damaged O2 sensor in my case I believe. The downpipes and O2 sensors have been installed like this for months before the code popped up...

One of the rear O2 was damaged a few years back when I first got the AR DPs, replaced with spliced Bosch O2 from autozone. Sold the AR DPs a year ago and it has been running up until now. Installed the VRSF DPs and Cobb Stage 2 + FMIC and now getting this code. I marked the sensors when I uninstalled the OEM DPs so they should not have been swapped. I will test the sensor and see what is wrong

Thank you Ian, I purchased my AP from **********s. And they were awsome. Alan told me when I receive the AP they will walk me through the process. I know it seems like a simple process, but when it comes to my car I get a bit nervous that Ill mess something up in some way. lol So if I need some help it sounds like Alan will walk me through it. Does that offer also stand through your company? If Im in need of some help could I call and someone walk me through the install? thanks again. John
