How would that change the lisence? I thought it was VIN related, and the vehicles VIN would be put in the new PCM.

Just a hunch, but I think the PCM is doing that to test the rear O2 sensors. A good working catalyst will leave the rear O2s relatively flat, so the PCM occasionally will "spike" the mixture to...
I was logging a few runs, and noticed -7% fuel trims in the 100kPa column up to 6000 RPM. Why did these show up? At WOT, fuel trims are disabled, why is it taking fuel away? What is the PCM...
Yes, if you turn off the code, it will show as "Not Enabled/Not Supported" which does not count against you during inspection. I do inspections in NC and our years are the same: 1996-2000 can have...
The higher the IAT, the more timing that is pulled. Therefore, the cooler the IAT, the higher the spark advance.
Not sticking up for them, but is it possible its a MAF with internal IAT, that they modified to read, say, 10° cooler? Just throwing that out there.
The analogy of the sloppy linkage is a great one. Here is one example of why hysteresis is used:
Lets say you switch from Fuel trim cell 12 to 13 at 2000 RPM. If your cruising right at 2000 RPM,...
