Wideband (Innovate MTXL Plus) analogue output
So I just installed my innovate MTXL Plus wideband into my Rev 2 by replacing the oxygen sensor on the exhaust manifold.
The MTXL Plus has a yellow output wire which it simulates narrowband which you hook up to the original oxygen sensor wire so the ECU stays happy.
What voltage on the O2 sensor is stoich meant to be at? I've seen some people saying 0.45 volts is correct for stoich. Others 0.5 say 0.5 volts. The general consensus is that oxygen sensors run between 0 and 1 volt but the range doesn't matter so long as stoich is correct.
Currently since I didn't really know my range is 0.1v to 1.1v and stoich is sitting at 0.39 volts.
Anyone have experience with this?

Re: Wideband questions
I prevailed though experimentation. It seems for the MR2 at least 0.45 is stoich.
Car starts up running a little rich around 13.2 ish AFR and slowly climbs to a steady 14.7 AFR after a minute or so.
These are my new settings for anyone thinking about the MTXL Plus like me.
