Based on what little I know of them, the architecture of both the software and hardware are different in the PC2 and PC3. The maps are not interchangable.
The PC3 is superior for these reasons IMO.
- The connectivity is via a USB port and not a 9-pin serial port (which most new computers no longer support).
- It can be used with only one fuel table (maybe not optimized, but still tweakable). It has the options of an individual table per cylinder.
- The PC3 fuel table changes are more straight forward than the two or three tables in the PC2 software. Easier to visualize and alter.
- The PC3 is newer technology - likely to be supported longer.
My guess is - at a minimum, the firmware and software are different from bike model to bike model (be it PC2 or PC3).
Even if the wiring harness connectors could be swapped, what would you use as a guide? How would you know the pinout of the new connector relative to the PC? There would be more reverse engineering required than it is worth.
Simply buy the proper model, plug it in and use it.
