I'm not sure that the PCM wouldn't be able to keep up, keep in mind that what you see on the scan data is what the PCM is reading as input from the sensor. Given how fast it reads O2 values and degrees of timing, I would doubt it couldn't keep up with temperature change which isn't near as drastic.
