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 The previous version was outdated and no longer supported.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

I just purchased a brand new leftover 501s. I plan to ride the rocky mountains allot this summer and from what I understand this bikes EFI does not auto adjust for altitude. I had a dealer tell me he recommended the stock tune for high elevation.
What can I buy for it so it will take care of itself?

Thanks
Mike
 
I might be misinformed but I believe that's the major benefit of EFI (to adjust to conditions automatically, unlike carb'd models). I have read that if you start the bike and let it idle for 5 whole minutes without touching the throttle or anything then the ECU will adjust for temp, elevation, and humidity levels.
Try it, seat of the pants difference would be the biggest tell tale as to whether or not this procedure has any effect. Peace
 
I spoke with a dealer at the races yesterday and he said they do not compensate for altitude. He mentioned they have a large happy spot so in general they get away with it. I was thinking a power commander with auto tune????
 
The stock ECU handles altitudes just fine. I have taken my 501s from the Mojave desert to the 9,000 ft mark with no problem. Just be prepared to have the radiator fan running most of the time when you are climbing.
It's a great bike and you should have lots fun riding around Colorado.
 
Your bike will run great at altitude! Stock these bikes are tuned on the lean side especially the highway going versions. Your bike likely may actually run better at the elevations you speak of than at sea level.
 
If you are in the Colorado Springs area this summer hit up Jeff Slavens at Slavens racing. Pay him a visit. He would be stoked to talk to you and has quite a bit of experience tuning both carbureted and EFI bikes for high elevation. He has got a great online catalog and informational videos on the Internet.
 
Jeff ported my last KTM300. I would love to look him up. I have my TPS set to .62V and all else is stock. What should I change first?
 
Best thing to do is to get the EU offroad map installed (part# KM796EU17G0201) and then play with the TPS. If your local dealer won't do it, send the ECU off to Munn Racing....
