Are your ratios similar in the .10 (0% pi) and .20 (70% pi) columns? Since idle loads after the engine is up to operating temps tend to float between .14~.20 g/s, I noticed this is where AFR will fluctuate quite a bit. I'm assuming the fluctuation in the di/pi % has a lot to stay about the fluctuating AFR thus the fluctuation in the fuel trims.
fluctuating fluctuations have fluctuated...
