Rather than installing a second bung into the down pipe for the wide band sensor can the PLX narrow band output be used for the PFC O2 input and eliminate the stock O2 sensor? I don't know if the PLX narrow band voltage tracks the same as the stock O2 sensor.

I have the PLX Wideband output going to the Datalogit AN1/AN2 and I have the PLX DM-200 IMFD display for the visual gauge; so that still leaves the PLX narrow band output available for use.

 

I don't know about PLX, but I do that with my Innovate LM-1.

 

Great - does it track to this graph?

 

Yes. My slope was a little less steep, but I have to play with it a bit. I also use the other analog output to drive my AFR gauge.

 

Thanks
What is the LM-1 AFR is at:

• 0.1 V
• 0.5 V (should be stoich.)
• 0.9 V

That would tell me if the PLX is the same as the LM-1.

 

The car is in pieces right now. It should be back together within a month
