Have any of you used a Wide band air / fuel ratio gauge for carb tuning?? I was looking at these ones. http://www.autometer.com/cat_gaugedetail.aspx?gid=3603&sid=15 http://www.aempower.com/ViewCategory.aspx?CategoryID=67
I had an older cyberdyne afr gauge, yet I didn't feel like it was accurate enough. I don't know how the newer stuff is. One thing I strongly suggest is learing how to read plugs. This can tell you not only fuel ratio, but timing and heat range as well. Combine reading plugs with perhaps an AFR gauge and you'd have a pretty darn precise idea of what's going on in the engine. http://www.dragstuff.com/techarticles/plug-pictures.html http://www.4secondsflat.com/Spark_plug_reading.html
The cyberdyne was likely not a wide band o2. A narrow band o2 sensor /gauge is a colorful display that tells you nothing. It looks sick on the pillar of your Civic though Wide bands are $400.00 and narrow bands are $80.00
