Car: 99 civic si
Motor: b16a2
Turbo kit: GReddy TD-05 18g
Tuned on: hondata s300

My car is tuned to not recognize o2 sensors on hondata, yet I keep throwing an o2 sensor CEL. When it comes on I can shut the car off & turn it right back on and it goes away. It comes on like every 2 days or so. I brought it to the shop who tuned it (Absolute Pro-Formance in Finksburg, MD) and he couldn't figure out why either, they are deleted out on my tune but it continues to come on, also not sure why it goes off if I just restart my car

Any answers or suggestions?

 

Anyone?

 

Try the forced induction section.

 

Did you disable it or the tuner?

 

The tuner did, I had him hook it up again when it first came on and he cleared it and said it was already disabled and not sure why it came on. But it's back on :/ and thanks I didn't even think about the forced induction section

 

No...don't try the FI section. Try the tuning section. Completely different section. We don't talk tuning in FI, we talk FI.
