For what it's worth, I have a couple of these that I bought the "GP760" version with the Yamaha plug and they all came programmed with wax curve and the Yamaha settings, I just set up my first zeel on a Kawasaki which came as the "Kawasaki" version with no plug, and it was completely not programmed, I had to set all of the settings as shown below.
Curve 2 is the Wax curve, Curve 1 is a slightly milder curve that I pulled out of my backside based on mashing together some other curves I've seen for Kawasaki motors online.
The static angle was set with a timing light and I was surprised because I have seen conflicting different numbers for Kawasaki static angle and what I measured matched none of them. BUT....I am not confident it is right. I set it only while cranking then double checked it running but i couldn't really get my head in there to see the mark when it was running because there was a fuel tank in the way, so don't trust it, check it yourself with a light (I'll be double checking my own soon). Also I have a wierd combination of a 650 motor running 750 electronics for the zeel so that might or might not affect the static angle.
Totally unrelated thing that I found interesting. I was checking the angle using the "+ only" triggering and noticed that with plus only triggering the motor has to crank a few times before the cdi starts firing, with "+ and -" it starts firing right away. It makes sense that with (+) only it has to get a few triggers in there to calculate an rpm value, with (+ and -) it doesn't. So to me that is the first actual good reason to choose one over the other for a watercraft, so I'm using "+ and -".
