'95 993 engine - any reason not to install the LM-1 O2 sensor & use NB outputs?
 

I want to install a new O2 sensor and have a dyno tuning session setup for next week. The '95 setup only uses one, pre-cat. I can buy the INNOVATE BOSCH LSU SENSOR for $60. This is the wide-band sensor which comes with the LM-1 unit by Innnovate.

Is there any reason not to use this item and adapt it to the factory O2 sensor connector? I would simply connect the Narrow Band output to the factory O2 sensor input.

I believe I'd be left w/ the wide band output for future tuning use.

Am I looking at this the right way?


Thank you,

Doug

You could be opening Pandora's box. If it were my car, I would just install a separate O2 sensor bung and run the Innovate one independently of the one that runs the fuel injection. Easier, and no messy wiring. Sometimes the O2 sensors can be sensitive to wire splices...

For the record, I spoke with Innovate. The Narrow Band feed comes from their DSP box (the narrow band signal is simulated) rather than straight from the sensor. They recommend not using the box as a narrow band source, at least long term. I thought the sensor themselves were providing both NB and WB signals.

I will buy the factory OEM one. Wayne - thanks for your advice.
