Ok I finally was able to get around and take off the exhaust to knock out the guts of the cat.
Which was badly melted. Which means the other one probably isn't too great even though it passed my backpressure test.
Also, I did have time to do a quick test drive and log the data, which I uploaded here.
One thing to note is I forgot to reconnect the bank 2 O2 sensor so disregard the flat O2 reading and probably fuel trims on bank 2.
The most important thing however is it ran much much better. Its far from 100% but it only knocked a few times and then spark retard decayed quickly enough so it really didn't cause me to have a substantial and/or continuous loss of power.
I think at this point other than readjusting the valves, hooking back up the O2 sensor and a few other minor things. I am ready to start tweaking the tables.
Or is there something else I am missing here.
