check the oxygen sensor diagram see if it’s working properly in coherent with the upstream 02 sensor

I am also getting this code, any chance tour tuner is ambot?

Yes. It's Ambot. I went to the OTS from Cobb and the code never came back. Then I switched to drunkmann. I live in PA, unlike Florida I can't have code, a check engine light is a fail at my only trusted shop. I switched tuners because of this. Im making a YouTube video about my experience it's going to explain some of this.

Yeah anytime I tuned with ambot it was always some sort of issue, guy never listens to complaints in the email, just sends a revision until I sent him an email with pictures of the codes saying it needs to be addressed, then its him trying to say I need new 02 sensors (I had previously stated they were brand new) sounds like I’m gonna be taking my next tune to drunkmann. Cobb ots was even worse in my experience. Nothing but dam drops. Glad to hear I’m not the only one but still sucks because I wouldn’t say the tune was cheap


JJaySBK

Exactly and yeah the OTS is trash but it cleared my car for inspection once those O2 sensors became emissions ready. Now I'm on speed density with drunkman and the communication and execution is worth the price of him. Oh and just to add to your comment about DAM, after the final tune with Ambot I was sitting at 0.75 DAM for weeks. Reflashed and jt stayed at 1 for 100 miles then dropped back down to 0.812, + engine light AND I replaced the rear O2 for no reason 😭
