I joined a similar forum about ten years ago, might have been this one. In early 2019 I had a house fire, and lost my computers, hard drives, notebooks etc, so I don't know what user name or other data I might have used.
Some of you might find my project of interest. Go to my web site, select Automotive and scroll down to the Stiletto project:

I drive the Stiletto for several years, then had a wiring meltdown. We never found what had caused it, but a lot of things were destroyed including that cheesy plastic box with all the fuses and relays. I had done two Nissan Skyline engine swaps, had lots of spare parts including ECU, Cam sensor. throttle body, etc, so we decided to make the project really interesting and converted everything to the Skyline. Both engines are straight six, dual overhead cam, but the Skyline has a Cam sensor, whereas the Z1300 has only a crank sensor and uses a lost spark system. My machinist mounted the Nissan cam sensor to the exhaust cam and the rest was pretty straightforward. I will post some photos of all this stuff, including the custom intake manifold, when I get a chance. All my existing photos of the conversion were lost in the fire.
We sent the ECU to Nistune, and they swapped one of the circuit boards for one of their design which allows custom tuning. They assured us we would never be able to make it work, but after a few tuning sessions my Tuner expert had it running perfectly. More later.
