Honestly I prefer to have an osiris system which would allow me to switch maps and what not. But I guess beggars can't be choosers.
^If it works out, you won't have to drive anywhere 
Assuming we get all the bugs worked out, the guy I'm testing the harness adapter for will start selling them. At that point, all you'll need is the adapter, and a newer ecu (and the osiris flash assuming you want tweakability)
Won't really know much until I can get this thing tested (which I'm very eager to do)
Even then, there may be some issues to work out... we'll just have to wait and see.

^not sure. I think he used the FSM for all the pinouts... though he did have me doing a handstand in the passenger floorboard to double check some things
Why not just sell you car and get one year newer?? Seems way easier and you might even break even/make some cash.
I got the harness, tested it (didn't try cranking because of a couple sensor issues) collected plenty of data, and sent the harness back for a couple little tweaks.
I'll update you guys once SurraTT gets done tweaking the harness and sends it back, although he's been very busy on an engine swap project.

Will be testing again soon. Just been insanely busy! ya know making a new generation of Maximas... 5.7 gen!
There are a couple different ways to go about this. With my new setup im going to try the zecu swap again but differently. This could also be applied to the early G's
