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?

 

go on the hondata website and look at their notice regarding how to tell if you have a genuine or counterfeit s300 board.
next suggestion would be to post your current map as an attachment on here so one of us tuners can view it to make sure the o2 is actually deleted properly.

I know it's not counterfeit, I bought it from absolute pro-formance, they're an authorized dealer. Also, how would I be able to get my map so I can post it on here? Sorry, I'm new to being turbo, don't know much.

 

you have everything at your disposal to be able to tune your car. download smanager from hondata.

then

see s300 installation.

this will give you the ability to download the map from the s300 unit onto your computer. you can then print screen shots of the parameter windows that house the closed/open loop options as well as the o2 heater.
