I'd like to add a note. People say swapping the injector pinouts work in theory, it doesn't. My car doesn't run right after doing the swap.

if you repin the harness correctly the z32 ecu works flawlessly, a customer of mine had me chip a z32 ecu at the same time I converted his harness with intentions of switching over to that after it was up and running on stock ecu.
ends up stock ecu was fried and car was at a no start situation, i repinned the harness for the z32 and after some trouble shooting (stock ecu fried a fuse) it fired up first crank.
