just put about 1000 miles on my car since the downpipe install / tune.

cel just popped up and onstar says its the rear o2.

i spent the extra money on a catted dp to help eliminate this problem. BYT says he can tune it out but its still an annoyance.

tried calling zzp for 3 days and no answer

 

Get BYT to disable the code. ZZP can't help you. One performance cat is not as effective as the OEM double bubble choker. Could be the Torque inj disable DFCO code as well, used to get that with the table all zero's. What's the CEL code number?

 

I have the same problem. It went away once for about one day then it came back on. No fix for it, unless tuned

 

Just do a battery reset and keep on driving.

 

I have it set to 0's and 15's, def not that.

The code was sensor 2 slow transition or something along those lines.

 

Ya, I used to get that one also before I disabled it. Maybe twice in a year.

 

P013e. You're not getting enough flow to the rear O2 sensor because of the way that pipe is designed. ZZP has also posted on here saying you can get a code from it.

The Hahn seems to be the only one that is reliably not throwing codes.

 

If you called tech support, it's a call back only system.
Email is our preferred method of contact.

 

Yea ive been emailing them back and forth for the last few days getting some piping and stuff and they replied within minutes alot of times......

 

I had p013e, p2096, etc...

I got all the p013e codes removed, they'd come up after about 30 miles... the p2096 takes about 700-800 miles... I usually just delete it... i'm thinking about getting vince to remove it as well though its near of the nuisance the p013e codes were
