PD or Iota for my upgrade?

I really do plan to post some photos of the interior of the PD9280 and how to make the mods I made. For WoodIsGood: he wanted to change the current limit during initial charging, with a switch. One way would be to add some resistance to the current sensor. There are several resistors in parallel that form that sensor, and typically one has been snapped in half. That is how PD adjusts/calibrates the resistance of that sensor. Adding resistance would make the UC3846 think more current was flowing. Then switching out that resistance would return it to the default current limit. Or, one could adjust the current limit circuit instead of the current sensor.
