Just a thought I was having about permanently fitting wideband O2 sensors in place of the narrowband pre-cat, on an Alloytech LE0 commodore. It is being supercharged and I like the idea of logging O2, and well having an excuse to play. I see the Zeitronics ZT4 can simulate narrowband output.
I've decided it might just be easier to fit another O2 bung in the exhaust and permanently fit a wideband O2 being logged by a banks diesel gauge. Now to have another bung welded into the headers. I'm currently planning on pre-cat on one bank, unless someone has a better mounting location.
Depending on how stringent the factory ECU is with regards to what signal it's looking for it's significantly harder to properly simulate the cycling between rich and lean that narrowbands do. Meaning - yes you can scale the output signal to be the range that the factory ECU is looking for, however it may look like a signal the ECU will find fault with depending on the controllers definition of 'simulation'.
