Wideband O2 inplace of Stock O2

Recommended Posts

Does anyone know if you can replace your stock O2 sensor with a wideband unit? I know some wideband O2 sensors have the ability to simulate a 0-1 volt sensor so that you can hook it into the ECU and a wideband gauge. Has anyone done this on their Esprit? The reason I ask is I don't have the tools at hand to weld in a bung and I don't feel like having it trailerd to an exhaust shop (she is not road legal yet).

You must be thinking of the Innovative Technology stuff. It is not the wideband O2 sensor which is giving 0-1V swings is it the post electronic processing of the data. I have looked at this, I have not done it but given out sensitive our ECU is to the right O2 sensor voltage response I have contemplated it.

I have put a 2nd port in for a wideband sensor, it is the only proper way to do it.

Hi All,

How about using the additional plugged exhaust-pressure-measuring-thread (which is already there next to the OEM O2-sensor) for the wideband sensor ?

Cheers

I would use the second port, but I had a custom exhaust built several months ago and of course they forgot to put in a second port. I guess the only solution is to install another port sometime in the future.

I've used the Innovate LM-1 system for a couple of years now. It has replaced the stock narrow band sensor using the emulator in the control (LM-1) unit. The test port, as is, is too small for an O2 sensor.

I've found it neccessary to use the Innovate extension to keep the wide band sensor from overheating 'tho.

Have you noticed any change in proformance side using the LM-1 to emulate a narrow band?

I drilled out the exhaust pressure hole and tapped it with the right thread tap for the wideband and installed my Wideband and LM-1... Here's a pic of the exhaust pressure bolt that I removed and re-drilled+tapped.

The exhaust pressure bolt is located just above the dial guage in the picture.
