sounds good JJ
i did interface the techedge to the S8. piece of piss, just one wire from the simulated narrow band output of the wb controller to pin 2 of the S8.
with the original software version, it will only take a nb input. later versions were going to take a 0 - 5V wb output, but don't know if that was implemented on any of the updated versions that i left with you.
i would recomend the techedge again, but with the bosch sensor rather than the NTK one. the bosch is much cheaper, so you are more inclined to replace it when it gets a bit dirty and the response slows down.
as i said though, the datalogging software for TE is not great, and looks better on others that i have seen like Innovate, Zeitronix or Dynojet
