If you look at the new software that is provided with V2, the wideband sensor configuration simply asks which channel the 0-5 volts is located be it an AUXLS, Inject, Ignit, AUXHL, Lamba1/2. You then set the voltage calibration values and viola, you have wideband readings.
Give Wolf a call and see what arrangement they have for your situation. If you bought it a little while ago before they changed their website, you may have a strong case for a free upgrade.
If it is the same Techedge unit, you can return yours or sell theirs.
