AusS2000

Wanted to have a bit of a look at fluctuations in my A/F ratio so I bought this little kit from a local electronics company.

I did a rough calibration procedure before installation (just set the 0 and 10V points) and wired it up to pin 16 on the 31P ECU connector (Primary O2 sensor).

Seems to work well. It shows both a bar graph and numeric value. I'm not putting much stock in the actual numbers. I'm just looking at the fluctuations.



This is not a permanent fixture. Just there for some testing. It's stuck on with velcro at present.

You can however buy another board and wide band sensor that turns this into a full wide band.

Still kinda cool that you made this thing.

I used to do a lot of these kits when I was a kid, but they are so much better now. The finished product is actually usable now.
