I'm thinking of asking Tischer if they can put together a kit with all the cooling components of the PPK but without the software. The idea being that people could install PPK v.1 and then upgrade it to PPK v.2.
You can get software only, but you can't get hardware only PPK. So what do you do if you want to upgrade?
A potential issue might be coding of the DME to take advantage of the larger radiator area and stronger fan.
