Default Windeband for the Link ECU

OK... I've been out of the loop for quite awhile but I'm back with another question...

Can you hook up a wideband 02 sensor in the place of the factory 02 that the Link ECU graphs under the listing "oxy" and see the voltage reading?

If so which 02 sensor would be best/cheapest?

The Link, as far as I know, can only use a 0-1V oxygen sensor. So, if you don't rearrange sensors or install a new one, the Link is operating off the WRX's rear O2 sensor.

Some wideband A/F sensor controllers can reduce their voltage output from their normal 0-5V signal to a 0-1V simulated signal. I'm not sure whether or how the Link would benefit from such a controller.

Yea.. I was thinking I could take one of these sensors and wire it in place of the factory rear 02 for more acurate reading. Of course I would need to make my S curve estimates from the specs of the sensor but I was wondering if anyone had done it or had any sucess with it.

By the way what sensor can simulate 1V and hook up with two wires?

The people who supply the wideband sensor controller described at http://www.techedge.com.au/vehicle/wbo2/default.htm expect to have a new enhanced version of their controller ready by the end of the year. The new version will allow logging of RPM in addition to A/F ratio so that the logs can by sync'd to logs from other sources (like the ECU). The new version will also supply an output that simulates a narrowband 0-1V sensor, so that you need only the one wideband sensor to drive both the ECU and the A/F display/logger.

unless you can change the way PCLink reads in the value (from 0-100), I don't think it would work. If they gave you the ability to calibrate this, you'd be fine...
