Default Wideband O2 question

I have a 92 and am wanting to put an A/F gauge in my car with my nitrous setup. MY questions is this, if I get a wideband O2 sensor, can I nook the cars computer to it like the current narrow band sensor or do I need to have a whole new bung put in just for the widband and the gauge?

I installed an Innovate WBO2 sensor and it has two programmable analog outputs. I have one driving a gauge and the second is programmed to emulate a narrowband sensor for the PCM. Works great.

Can you be a little more specific about the gauge you went with? I see they have one thats discontinued, plus a cpl of other choices. The MTX-L looks like it might be a good choice, it is here:
http://www.innovatemotorsports.com/products/MTXL.php

it specifically mentions 2 outputs, so I think it will work. Thanks so much for the link and info!

I bought an O-Meter/LC-1 combo from Moates:

http://www.moates.net/ometer-and-lc1....html?cPath=48

I usually have a netbook mounted in the car so I use LogWorks as a virtual dashboard most of the time. I use the O-Meter as a simple/cheap way to watch AFR when the netbook is not in the car.

For details about the LC-1 look here:

http://www.innovatemotorsports.com/products/lc1.php

I also have a couple of SSI-4 boxes to monitor other sensor data. Not a bad data logging solution really.

Here's a picture of the screen:



Not a great photo but it's all I could find.

So Is this the only one from innovate that I can run simulated narrow band to pcm http://www.innovatemotorsports.com/products/MTXL.php

This one you Can't ? because does not have 2 channels http://www.innovatemotorsports.com/products/db.php

Actually, it is the opposite. The LC-1 (which the MTX products do not use) has dual analog outputs in addition to the digital MTS serial datastream used for the MTS gauges (like the DB and G series gauges). Anything that includes the LC-1 to control the WBO2 sensor will allow a narrowband output.

My MTX-L has narrowband sim. I likely wont use it due to already having a bung in my passenger header and 85s only use one narrowband.

Need to install this sucker.

Hum funny Cuz my MTX-L I just bought does an its in the car running. Analog narrow band to pcm / Analog wide band band into Hp tuners an calibrated within in .1 ARF

From the manual that came with it ....
Connect the MTX-L to the computer and launch LM Programmer.
2. Select one of the Analog output tabs. The Analog output page looks like this:
