• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Per the shop manual (thought I'd post it for those that are wondering and do not have the shop manual)

ELECTRONIC IGNITION SYSTEM (TE-SMR)
The ignition system is controlled by the ECU (1). The system belongs to the category of the integrated systems of digital electronic ignition
with advance and static distribution and gasoline electronic injection of intermittent sequential balanced type. This ignition system
consists of a sensor of the crankshaft position (Pick-up), an ECU, an ignition coil and an air pressure sensor of the intake manifold. The
feeding of the ignition coil is supplied by the battery with a power relay and is controlled by the ECU. The synchronization of the ignition
is checked with precision with regard to the engine r.p.m. and the position of the throttle control. Besides this basic condition, also the
temperature and air pressure sensors and the coolant temperature influence the synchronization of the ignition.


Obviously the English translation is not perfrect, however it is better than I could do explaining the system.
 
Yeah, that's the mechanics of it, but what's the code look like?

Ever notice how your bike sounds when you first start it cold, then what it sounds like after running for a bit? Sounds like the ECU is making a few changes.

I have noticed a difference after the first 10 seconds of operation and initially thought is was the oil system re-pressurizing.

The system has a coolant temp sensor that impacts the FI system.

What do you mean by code?
 
The software part. How the program is wrote, or how each part effects the system as a whole in the logic.
