Finally got the nerve to do some scans on this thing. For ambient temps in the mid 80s, it did quite well. The "all data loaded" mode on the histogram shows no Knock Retard (KR) anywhere. That was a welcome surprise, and may be the best I've ever got under similar conditions. IAT was taken at the MAF inlet, not in the UIM as I prefer to do.
PSI peaked at about 11, and charge temp rise at the IAT sensor was 16 degrees:
The engine wear and tear has caught up with us, as the ongoing misfires I've had on #1 have gotten worse, and #3 and #4 are starting to join in. So it's been intermittantly throwing P 300 and P 141 codes, usually before it warms up. A couple times I did get a flashing SES, which after a short time things seemed to pop back into place and it ran "normally."
