Why not just use a 760 front cover like we are
DIY Total loss or MSD TL upgrade box 270USD?

And by the way, the only part the JSTL produce "them self" is Flywheel made by ET and pickup plate, guessing also ET.

I think we would, and will if we ever get a another ski to build.
But for now the whole idea is to adapt to a existing total loss setup
That's what I would do/did but he seems set on trying to adapted with an msd. Wich seems like more trouble than it's worth

A couple things to remember about these boxes. The max timing advance is linked to your static timing. If you set static to say 30 you cannot advance more than 30 no matter the curve advance. Second if the static angle is set to high as in incorrect, the advance curve will be less than programmed and visa versa . I would like to know how you varified that 54 degree number as static timing ? That number should have been the trigger point after tdc. As per Zeels tech the advance becomes too unstable after 45 degrees. They rec less if at all possible. I've tried this myself and can deff see the timing becoming unstable. The time delay will help at lower numbers stabilize this

Have you run one of these yet? Angle is 56 if I remember correctly. Runs smooth and stable per Wax curve at least with a few people going years on these boxes with zero issues. We run 0 degree static and advance through software.

Been using these for years on the motorcycle side as well as the watercraft. That's what these were designed for motorcycles. Tell me how you varified your static timing or are relying on someone's info ? The static timing will vary with different stroke motors as well. The static angle is most critical on the accuracy of these units. Yes your ski will run with that static number but is the advance curve correct ? Again I'm asking how YOU came up with that number ?
That's what I thought

Why do you take offense to me asking you if you’ve ever run this specific cdi and 760 electrics? No I didn’t measure my angle myself- yes I relied on someone who I trust and knows more info about this stuff.... if I blow my motor then that’s on me. Relax.

I have not put a timing light on mine yet. So I may prove myself wrong by doing so lol.
But...
Isn't the advance stability thing more of an issue at low rpm/cranking when the rpm variation throughout the stroke is very high, and the ignition advance is very low so there is a big difference between the trigger point and the ignition point which has to be calculated?
The unit that I (and I think everybody here) use has a feature where you can use the "back" of the lump for the cranking ignition advance below a certain rpm to help deal with that issue. Not all models of zeeltronic have that feature, if you are using only the "+" signal there is potential for kickback on cranking.
I had some (although admittedly not much) discussion about this with Borut when I was first looking into this and he didn't think it would be an issue in this application.
I do appreciate bringing this up if it's a concern though. I've mostly been leaning on what Wax and a few others have been saying. They seem pretty knowledgeable and so far I have had no issues, but it is possible that they are there and I have not discovered them yet!

Also I'm not understanding why static timing for the zeeltronic would vary for different stroke motors. Isn't it just the angle in crankshaft revolution between the trigger point and tdc? How would that change with a different stroke crank?
Anything having to do with the relationship between piston travel and crank angle would change, but this parameter depends only on crank angle.

anyone see a problem with me running 760 flywheel and stator/cover with my 61x e box and associated parts i would need to re use? i want to ditch the charging setup, will the zeel cdi fit in the oem box? thanks
Been covered already, it fits in 760 ebox but not 61x/t without modifications

You can use most of the parts from your 61x ebox- just get the 760 ebox plate and cdi rubber sleeve. The rest of the internals will work minus the obvious stator

cool thanks
You won't blow the motor ,your running timing would actually be less than what you have programmed. Your safe. Read the info at the bottom. You may be just leaving alot on the table power wiseQUOTE="Chase Musetti, post: 1990587, member: 22979"]Why do you take offense to me asking you if you’ve ever run this specific cdi and 760 electrics?

It's not a lot of difference. Only 10ths in millimeters
Because of the dwell at tdc
