Electronic Ignition for xs650

that is also scots plan to use a dual output coil, wonder who will try first, there is a total of 7 members now with these ignitions including you.. I will order three more if there is an interest for them,

It may be installed soon, but not tested until about March. I think I've changed my plans. I may go whole hog on the installation. Someone has to do it, try it. 3 ohm dual output coil, Tytronic's orange and gray wire spliced together before connecting to the coil primary. I'll use no diodes or ballast resistor, maybe an inline fuse on the red wire of the Tytronic.

the second set of three has all sold, I still want another one for a bike, so I can order 3 more at the discount of 75.00 each if I have 2 people interested ,
the last three are shipped you guys should see them within the week, first class USPS
 
so again Im calling on the pixie spark wranglers out there, you guys know who you are, I have one guy here in Portland but I think he is kinda a novice, there isn't that much to a E advancer, althou What I want to see is an e advancer that we can select our advance curve for things like gasoline quality, or higher compression, or whatever may require a costomised curve, AGAIN Im not trying to produce something to put anyone out of bussniess and since there isn't already one out there that does that customized curve, ALSO Im talking about doing this as a collaboration, and OPEN SOURSE , that means the plans are free to see and change if you think you can improve upon it.. I might even contact some guys on an electronics forum, if I knew what I was looking for lol
anyways WE can have it , if we stop waiting for someone else to make it and we do it ourselfs

I was thinking about something that applies to this, in regards to the ignition code start i wrote awhile back.

Imagine a "black box". It has an input side and an output side. The box determines rpm by the time between the _last_ two pulses it received on the input side from the trigger (trigger on crank, or up top, wherever) and uses that rpm to adjust the timing of the output pulse on the output side on the _current_ cycle. It's much simpler than using the two close pulses of the normal tci trigger to do something similar. This is no doubt what Pete's e-advance does. Also, it gives you the theoretical possibility of using a broken tci pickup, where one coil is open... Also, would let you use one of those boards I linked to and not have to add much electronics -- it would basically just be spliced in in the middle of the existing electronics

**Rotary switch option allows you to select between the four timing maps loaded into memory, even while riding.

I have a machinist that runs a cnc machine that will be able to pump out backing plates for us, I know this is still in the zygote stage of creation, but can I get a role call of those willing to attempt to help create something, thanks

here is one on a Yamaha xs750/850 triple...it 700.00 dollars
You can choose an optional Rotary Switch kit, which allows you to change timing maps during dyno runs or while riding

2many conjectures that diodes might be a good idea.

No, that wuzn't me.
If the electronic ignition is the simple "grounding transistor" type (like points grounding), then they can be tied together to drive a single dual-output coil. The catch is the *dwell*. If the dwell is too long, one module could be connecting to ground before the other has a chance to "open up", or connect to ground before the other module's "open period" can complete its ignition timeframe. This won't break anything, it just wouldn't spark.


Good one, Gary. That's the same circuit, in principle, as the old Martek ignition...

I installed a Martek on my Suzuki GS850G waaaay back in 1981 and it was superb.
 
I also have a Tytronics unit that like gggGary's it is sitting on the work bench. I was waiting for someone to figure out the coil or coils and the advance unit. It seemed like a good idea at the time, but............

In my defense I have installed fired up and run the Vape charging, ignition system on a bike that was a deep project. So there! :)
I just noticed the techtronics still sitting patiently on the bench today. :unsure:
