It works.Thats all it is.
I used the schematics to fix my cyberdyne. I shorted the 5 volt rectifier.
I would have built this if I found it sooner.

What kind of OČ sensor do you have? Stock Bosch? I guess you'd have to install one to use the A:F LED gauge...

Yes ,any muffler guy can install the bung for the o2 sensor.Mine is located close to the manifold on the downpipe. It's worth the trouble. Anyone thinking they can accuratly adjust the mix without it is probally missing the mark.I sure was.
