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 The previous version was outdated and no longer supported.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

Hi, I'm having fun setting up my snowbike and wondering what everyone thinks would be a good AFR table for my auto tune system. So far I have it ranging from 13.2 at the bottom end to 12.8 on top. In practice it's been leaning it quite a bit at 5000' altitude. Running strong, sometimes chuffs a bit getting it started particularly if I've stalled it somehow.
I'm new to detailed tuning like this. So these tables are a little advanced for me.
Speaking of advance, ignition is advanced on the PCV map I have in the top ranges of rpm/tp. Is there a way to tell what is safe amount of advance at these altitudes?
Also, I've got the startup fuel box checked, and 10 seconds time with 15% fuel added. Is this a good idea? Would more fueling help the stalled restart performance? Sometimes I have to massage the throttle to get it started again when I feel it trying to catch.
