Number of ECU Cells vs PCV Cells

[SimiPair]

So, if PCV has roughly 400 cells and the ECU has roughly 800 cells, does the trim % get applied to both of the ECU cells covered by the PCV box? What if the two ECU cells have different fueling values?

The Gen1 busa has quite a few more cells than that in the ECU...

I believe how it works is that the PC applies its settings based on TPS/RPM location. it applies its values on top of what is being applied. if the ECU is sending 10 (just for round numbers) and the PC has a 10%+ on that, it applies 11.
