The module mates with the programming software, and the page with the advance curve looks like this:

There are other pages where the rev. limiter can be set and where it can be chosen if you want the programmable retard to be related to the throttle position or a vacuum sensor.

This is really cool.  I probably didn't read carefully enough, but did it perform well straight out of the box?  Or did you have to tune it?  You have some significant modifications on your bike if I recall correctly.

Thanks.  That’s awesome.  Nice find!  I’ll abort my plan to find a manufacturer able to produce an affordable igniter.

I was able to root through the website, and I found additional info.  They have a lot of instructions in PDF format.  A lot of this stuff is way above my feeble capabilities.  I need to study up.

I can see their MAP sensors have a range of 1 to 2 Bar.  That's like 30 to 60 inches Hg.  Seems to me that would be used for engines with a turbo or blower.  Do I have that correct?  

This looks like the perfect candidate for a step-by-step post on exactly how to procure, setup, and install one of these ignition systems (blow by blow, wire by wire).  I don't think I could do it.  I don't have the skills.

 Looking over this thread it appears I have some confusion.  When asked if the module required any tuning, the reply was:

The module arrived preprogrammed to fit the bike as it came, plug and play as advertised. These guys really know their stuff.

 But then there is this information:

If you got this thing running, you are an absolute wizard.  My compliments.  I see in their description that they custom make the module with a plug that is compatible with your existing motorcycle harness.  That's certainly a nice feature.


 So by "plug and play" does it mean it just plugs in easily but needs programmed?

All:

Please excuse me for starting this up and then not giving it full attention, but here goes:

Mike: The prolific driver is a piece of software that enables the windows to connect to a serial interface via the USB port. I advice you to just get it here: https://support.lenovo.com/dk/da/downloads/ds034089-prolific-pl-2303-driver-s... install it, and forget about it. It will work ok with this ignition module. (it did not work flawlessly with the MIDI interfaces I have worked with, but that is another story)
I don't understand why the module is equipped with a serial interface instead of a USB interface directly, but I guess the guys at Ignitech have their reasons.
When I started to communicate with Ignitech, I showed them the scope shots of the output from the trigger coil, photos of the interface plug and a drawing showing which pin went to where in the harness.
They are obviously used to work with all sorts of bikes and are accostumed to the plugs and sockets used. They have them in stock.
I also told them that the lowest advance possible is 3 deg.BTC, as you have shown, and that the maximum advance possible is 37deg.BTC.
With this information they delivered a module that was pre programmed to work with the single slug reluctor timing plug that is equipped on the early LS650.

The later ones, with a longer slug will quite possibly need another firmware installed by Ignitech.

So, in short: If you own an early LS650 you can buy this module, plug it into your bike and run it as it is. No further programming is needed to run just fine. It will come with an advance curve that tops up with 35deg. advance at 7000 RPM which is fine.

However, the reason to go into all this was a desire to be able to fine tune the advance curve. Mike has a desire to take some of the advance out at WOT, and there may be other wishes too.

What can be changed and what can not:
Due to the ease of programming the changes into the module, and supported by the fact that it can easily be retrieved again from the module, I think the module is built in 2 sections: One section is programmed into a Microprocessor, and is the part of the module that constantly compares the input from the trigger coil and produces the timing signals for the ignition coil. I will call this the "Core". Then there is the data we read into the module with instructions of how to advance the ignition relative to the RPM. This data is probably stored in a PROM Programmable Read Only Memory.
Then there are the 2 inputs which can handle either a vacuum sensor and a Throttle position Sensor to add info about how to retard the timing during WOT.
The core is constantly reading from the PROM and the 2 inputs to produce the desired spark timing.
There are also 2 outputs which can generate all sorts of usefull data, like drive a servo motor to modify the inled port of a rotary valve 2stroke (This has been done) others have stuff in the exhaust that can be driven by the module.

As you all can perhaps gather, I will have to record a video about the programming interface, because it has a lot of features, many of which I still do not understand, but the ones that I do, are hard to explain with just words and pictures. Stay tuned.

Oh, and by the way, the rev. limiter is of the hard type. No warning other than that of the ignition cutting out the moment the engine hits the programmed level. Not so elegant. Ignitech caters to the racing community, and I guess they don't care for the finesse of a soft limit. If it was a popular demand, I have no doubt they could program it into the Core.
