I am wondering if there is a way to check what the AFR is after installing an O2 Sensor extender? Can this be measured off the diagnostic port, like where I have had Autozone look to see what the CEL code was when the light came on a couple months ago?

I have seen a graph posted showing what the AFR is in relation to the voltage off the O2 sensor, but can not find it anymore.

Really just curious to see what changes it will make with just the extenders. I have a pair of the extenders and will be installing them just to test it out. Still working on my HHO cell and have not tested it yet, but getting there soon.
