• 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 The previous version was outdated and no longer supported.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!

will leaving the battery disconnected for a period of time reset the efi/computer like it does on vehicles and other bike?
 
Disconnecting the main battery does not affect my 2011 TE310's ECU.

However, the bike won't run without the battery connected.

It should not.

Most ECU's use "EPROM" (electronically Programable Read Only Memory) type memory chips which do not need an
"internal" small battery to retain data..........like laptop/desktop computers do.
 
Many brands and models have the ability to "reset" the ECM. Usually it is included in the diagnostic software for that brand. While it is included on Honda HDS tool/software, my regional service rep told me that completely disconnecting the battery, then shorting the neg battery cable to the positive battery cable, will accomplish the same thing. Maybe it's the same with your (unspecified) bike? It is critical that the + cable (both to avoid an accident) be disconnected from the battery or severe harness/component damage will occur.

It would be nice to validate a procedure/technique like that for the Huskys.........maybe a dealer tech would know.

There has been a lot of discussion on several forums about doing the Power Up procedure and if the ECU reverted back to OEM mapping when the 02 sensor was reinstalled and reconnected with the resistor removed on the 610s.
Some riders never returned to the higher MPGs they got before doing the PU mode and therefore they theorized the ECU was still in some form of PU mode after the restore.
