Hello Everyone,
I see that the AccessPORT can support various wideband O2 sensors like the AEM X-Series UEGO but can it be a replace my factory narrowband O2 sensor for tuning or would I use it in addition to my factory narrowband O2 sensor? Is a wideband O2 sensor something I install only for tuning purposes or can I keep it on my car? I've seen that aftermarket wideband O2 sensors don't tend to last as long as factory sensors. How long would they typically last?
My car is a 2007 STI, with an O2 sensor bung after the catalytic converter in the downpipe.
You'll need to retain the factory narrowband. It's not possible to replace it with a wideband. You can however, wire one of the analog 5V outputs from a wideband controller into the factory ECU using Cobb's custom features. This gives you the ability to datalog the wideband from the Accessport. Its actually quite easy to setup.
