Re: Wideband O2 sensor for tuning?

Hi JW,
Yes I am thinking about something like that SUN tester. A wideband oxygen sensor has an 02 sensor that you can either mount into the down pipe, or use as a tail pipe probe. It then reads/displays/records the air fuel ratio and -depending on the product, things like engine RPM. This way, you can plot your AF ratio over load and rpm....This is the tool I am considering, and it will be a while before I get to use it on the packard, but the porsche may see it later this winter. (Those carbs are getting rebuilt now with new throttle plates and throttle shaft bushings)

I think it might be a little over scientific for the packard engine, but more data is usefull to a point.

The OBD2 capabilities can't be used on the packard, but a code scanner would be usefull for my daily driver.

It is a pretty expensive tool for a hobby mechanic, but for the air cooled/modified engine it is pretty important to not run too lean under load and burn up.
