1.6 NA Adaptronic sale by Neogenesis2004 - is this workable for an NBB ??
 

Is is a question of harness or is it internals ??

I beleive that the pinout is the only different, so I suppose you could make an adapter harness. The adaptronic works on the NB's so I assume it will still have the stuff in the software to make it work with NB trigger inputs, etc.

Im just assuming though, dont take my word for it

The unit itself is identical, the harness is different. NBs from what I understand have different ecu harness connectors, so you would need to basically make a custom harness or wire directly to the car.
