Would it be possible to read the wideband signal in place of the stock O2 sensor? This would save on buying HP Tuners Pro version as I can just log on my laptop (no need for blackbox). I searched and didn't find anything on this. Turbo project should be all finished up in the next couple weeks
Actually, that won't work using the stock narrowband input.
However, if you get rid of your EGR, you can log the wideband through that. People do it all the time. You just set it up to log EGR (which is actually your wideband 0-5 volt signal, not the EGR 0-5 volt signal.
EGR is gone, I can't find anything about tapping in to it though. Which wire am I looking for? I've got my standard version of HPTuners now as well, the learning curve is a little tough but I'm starting to get er down.
Ac pressure switch works.
