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 The previous version was outdated and no longer supported.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

Mikuni EFI- You CAN connect to it WITHOUT iBeat!!

Hello all. After several months of messing with this, I have learned how to communicate with the Mikuni ECU without having to use iBeat. At this point, it is very clunky, but it works. I am working on some YouTube videos to explain, and an Android app to make it easier, but for now I figured I would post what I have learned. Unfortunately, it is only 15 years too late!!

This got really long, too long for a post, so I just uploaded a document. I am still working on sorting out some additional parameters.

If you have iBeat already, this is not an upgrade. It's biggest advantage I see is that if you want to test different CO settings you can do it on the fly without a laptop.

I am working on an embedded controller that will facilitate the use of bluetooth. It will also make it easier to use both Android and iPhone. Right now I have only tested with Android.

In this process, I have also built (on a breadboard, very janky) a serial to K-line converter using a 30 cent IC (LM2903 for you nerds) and a few resistors. This is beneficial is you want to build something to talk to your bike through some kind of controller. Or if for some reason the USB to K-Line adapters become hard to get or more expensive. But if you have a working cable and going to connect to the with something that has a USB port (which includes smartphones) then just keep using that.

Sorry this is coming so late after these bikes were made.

Edit- Rev 1.1 added 2/21. Includes error codes and a table of percentage from 95 to 150 with their Hex codes. Makes it easier to reference CO values.

The real short-coming to iBeat was it was still seat of the pants evaluation. Software that measured AFR was less subjective. Congrats on cracking the code.
