You can chip the JDM P30, you just need to add a few parts to the board. It's perfectly doable though, just a little more difficult than the US ecus that have the pins thorugh the board.

As far as running the Hondata with it, I don't see why not, but I don't have any direct experience with it, so I can't say 100%.
