    So presumably the advance and retard is electronic and contained within the short bean can.

    What does it cost?

    I would have to check the exact price but I thought it was just over 400€

    That is a really nice looking item and perhaps adds a better level of timing control over the stock (& getting scarcer) electonic bean can assemblies - but I bristle at prices that climb that high - and my "MacGyver" mode for building a substitue takes over.

    I think this is a better alternative over the Emerald Island set up that is out there
    I have had 3 EI Ignition module and they all fell short of the 26 degrees of advanced that they were marked
    I only got around 20 deg of advance
    But on the other hand the new Bosch bean can is unproven for long term dependability

    So you use the standard ECU? If so it means that advance/retard provision must be in the bean can?

    Visually, it appears to be a different unit from that which Prutser wrote about in the OP.

    Good to know there is a choice, your's being from Siemens and Prutser's from Bosch via BMW.

    Is the Siemens unit plug'n'play other than setting the timing?

    The "Siemens" parts look suspiciously like the EI stuff to me.

    It is EI stuff. Maybe the sensors are Siemens and Motorworks is capitalizing - err, capitalising - on that.

    I didn't get a long term test on this one. After stalling my bike out of the blue every time I rode it I took it off to return it to BMW.
    The bike did great when it kept firing. Noticeably better than the old type I was using(which was only one year old)

    Put new O rings on the old unit and it too will be hard to push on.

    If the unit does not engage correctly it will sit high off the mounting flange, so I think a carefull installer would realise that something is wrong.

    The new unit will be able to be taken apart .. might be held together with glue and a tight fit to make it much harder .. but if it was assembled .. then it can be taken apart, sometimes the first one is a learning experience and then others can be done with less destruction.
    Looks like carrying a spare unit will be much easier now - much less space and you might even have it on top of the unit in use.

    So does that mean you currently are not using a new one from BMW or did you get a replacement?

    At the moment I'm using my old beancan and returned the new unit to BMW. I hope to get a new one which doesn't cut out.
    For me the new one was just to feel if it was an improvement over the old one.

    We wondered whether it's made by Siemens and Motorworks are now just buying them direct!

    My understanding with the EI cans/ignition modules is the normal single spark advance is 21° and the dual spark advance is 26°

    I put the single spark can on my GS and at full advance the timing marks line-up bang on

    I've got one on mine - satisfied with it - timing was fairly easy if I remember. It's an Emerald Isle (EI) as well I believe
