I think my front O2 sensor (located after the turbo) is dead because my old turbo was smoking a lot and it's not connect to the ecu.
I'm looking for the cheaper solution for my engine:
Bypass 02 sensor but i don't find thread to explain how to do with 3 wires sensor.
Buy a wideband sensor but i have a stock ecu...
Can I use an blue or black apexi safc without O2 sensor?
Same question with an emanage?
Buy an universal sensor and conect it with a wire to the ecu?
Can I use SR20de sensor with a sensor simulator and wire it to the ecu too?
Other solution??
Need help Please!!!!!!!!!!!

Rear o2 sensor you can do without as long as you don't mind a potential check engine light. Front o2 you absolutely need. Without it, you are probably gonna continually run in open loop mode, meaning very rich, even at idle and cruise. Don't simulate the signal, as your car would probably go nuts trying to adapt the A/F ratio.
Get a replacement sensor. They are not that expensive. You can check online for prices. Maybe rockauto.com?

You need your o2 sensor. I don't know any type of modern fuel injection (even strictly performance) system that doesn't incorporate it.

I bought an AEM wideband and a blue emanage. I'm waiting for them. I don't how it's work or if the bosh sensor plug in my J pipe. So I read and read all thread

the aem wideband will not work as an o2 sensor

no 02 sensors over here and my car runs great but i also have a calum ecu where I can eliminate that

the aem wideband will not work as an o2 sensor
So I have to plug an O2 sensor? Can I buy an bosh O2 universal 4 wire? Or I must buy an Avenir sensor?

im pretty sure the o2 sensor isnt much different than the regular de one...

pretty ... is not sure lol !
When I said Wideband it's bosh O2 sensor + Aem gaudge why it doesn't work like a stock o2 ?? There is 4 wire n the bosh two for temperatur one for aem and one for ecu no(narrowband)????

The WB gives a different signal than a regular o2 sensor, so the ECU won't be able to work with it's values properly. Does the AEM guage come with a "narrowband output"?

Don't know. In my mind every wideband have a narrow output for ecu....

Nothing on Rockauto....
Can I try to plug my DE sensor and see with the aem if it working?
