I'm running a Hondata S300 and want to install a PLX wideband. I want to keep the stock O2 sensor for narrowband (and so I don't have to mess with wiring to fake the ECU out about the O2 heater) and install the wideband into a second O2 bung. If I wire the PLX's wideband output to ELD (ECU D10) and set that up in SManager, will that work? My concern is that the ECU will have two O2 inputs (narrowband at the stock location of ECU D14 and wideband at ECU D10) so I'm not sure how it will know which reading to use. Is the wideband activated for datalogging only and ignored otherwise?

Thanks!

 

No need to run a second O2 bung for wideband or fake the ecu with a resistor.

Dont need to run narowband sensor (unless you really want to) Plx has both wideband and narrowband outputs. (wideband goes to ELD and narrowband goes to stock input)
Narrowband O2 heater can be turned off with Hondata.

Wideband is used for datalogging/autotune, the ecu uses the narrowband input normally.
