Adding another O2 sensor

[Bruce Plecan]

They are at least as fast if not more so then the oem ones.
Remember the ecm is shooting for a 14.7:1  AVERAGE, do it hammers things
real rich and lean.
The oem one's ******errors****** is when folks try to read them as a WB.
They develope cross counts at the same rate as the oems, from what I can
see.
At the Powwow we had a scope on the WB and you could see the individual
cylinder firings, and how they swung rich lean.
