Aldon Amethyst ignition system

I've not had anything to do with this new system but thought it might be of interest to anyone playing with ignition on something like a VW. It seems to be something like the Leburg but programmable through a laptop.

Great spot.
That vacuum enabled version looks really interesting and is an alternative to the Megajolt system I wrote about in the LAA mag a while back (which is now fully LAA approved as a prototype MOD and has been flawless to date & improving economy).

Software looks good for setting rpm & vac mapping curve progression so a great starting point perhaps using different trigger methods than points or reluctors etc. Hopefully someone will run it past Engineering for their views.

Steve,

that article caught the attention of quite a few of us at the time, how about a follow up in the magazine please?

I have a vested interest in learning more about electronic ignition as I have a Walter Mikron (with alternator) destined for my project and a swap to electronic ignition from the original rear mounted magnetos seems a good way to potentially move the engine back a few inches to help with known c of g issues.

regards,

Colin

Glad it was of interest.
It initially sounds complicated but it isn't really.
Ok - I'll draft something up & get onto Brian - I was vaguely thinking about doing an update so thanks for the prompt

Thanks for the info.

I am very interested in electronic ignition and have been gauging Francis Donaldson's interest in dual electronic ignition, myself and another Potez owner are both hoping to install dual electronic Lightspeed ignition on our Potez engines using magnet sensors and magnets mounted on the starter ring or spinner backplate to provide timing. The Lightspeed system looks like a good system and is installed on other LAA aircraft but it damned expensive (~£2000 for dual system).
