AFR monitor and controller question
Discussion
A friend is having a turbo conversion into his car and is looking at fitting an AFR gauge onto his dash.
I have a PLX devices wideband controller that i fit into the exhaust via a pipe i put in the rear just to check fueling, they also do a little dash gauge which looks nice. Now my device also has a narrowband output, my question is can this be used to run the ECU's lambda input instead of its own narrowband sensor? If so can you use such a device so we wouldnt need to use 2 sensors but just the one wideband and controller to output to both the gauge and the ECU? or would the ECU rather control its own narrowband itself?
Cheers

At the moment there are no sensors in it as the conversion is incomplete. We will start off with the standard narrowband but if more mods come and he decides to fit an AFR gauge at least he wont need to fit a second sensor if the new wideband can also be used to output to the ECU. Saves welding extra sensors into the downpipe. My only concern would be relying on the one sensor and the controller to run the lot.
ETA: i have this controller www.plxdevices.com/M-Series_productinfo.htm
and we would be looking to put something like this www.plxdevices.com/products_SMAFR.htm into his.

The only issues in that case would be:
Does the wideband sensor that you're considering physically fit in the same boss as the narrowband sensor that you're planning to use initially?
Do you know the output characteristics of the narrowband sensor so that you can configure the wideband controller to emulate it?

Sensor will be a standard M18 fitment.
I am unaware of any calibration features on my controller for the narrowband output, but the spec states the narrowband output is 0-1v which seems to be the standard voltage on narrowband sensors.

OK, in that case you should be sorted. (I mentioned it because the NB output on mine is configurable.)

Thats the sole reason for having a narrowband output.
So you can easily mount the wideband in the std sensor location, for easy fitment, then simulate a NB output to keep the ecu happy, when you throw the NB sensor away.
