Hey guys. I went out the other day to work on my tune. After upping my rev limit 7 and doing low rpm ve tuning just like shifted's how to. I had dfco disabled and was in open loop just like is how to said. Now I started high rpm ve and everything was fine then like the 5th time I took it to 7 I got this. P0130 H02S circuit closedloop(CL) performance B. As soon as I had a key cycle it turned right back off so What's going on here?

That is because you have it in open loop. If the ECU see's the little movement from the O2 sensor for too long it does that.

Another reason I usually tune on closed loop
