aka951, yeah I forgot to mention you need a little "black box" to convert the wide range O2 voltage to one a a/f gauge can use. I found a zip file on the web saying how to do it but I can't find it now. It had diagrams how to make it and had the part # of the Honda sensor. I'll see if I can find it again.

Danno is correct, a complete wide band O2 sensor and meter is what I ment, they are much better than a ARM1 and such.
