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 The previous version was outdated and no longer supported.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

PCV with Auto tune 2013 TXC 250R

Have had the PCV for 10 months with Zipty tunes as delivered by zipty (Tinken Rocket 310 map) well on my 250 I haven't been much of a believer in the PCV. It wasn't bad, but nothing great.

I finally got around to buying and installing AutoTune. After a few trims, my TXC 250R runs great and has much smoother power as well as more power.

Couldn't be happier. After a few trims it is exclusively leaning the bike up through the whole range. In the mid it's about -20 to -30 and feels crisp as can be.

I'm on race map 3 and it obviously is too rich for the 250.

Very impressed and recommend to anyone with a PCV. Seems O2 sensor placement is critical and is dependent to make it work well from my research.
 
Good going with the PCV and Autotune. I was the first on the 13 Keihin to have Dynojet install and Dyno. But I asked for them to install Autotune as well. Was told ride it for a couple of days and autotune would probably still make some small changes. Map 3 was too rich for mine as well and Autotune sniffed it out and let me tweak a high elevation map. Jetting with no gas smell. Gotta love it.
 
I have been using autotune for years on several bikes and also helped other people set it up. I can confirm it works fantastic and allows you to build excellent maps.
I had dyno tuners pulling their nose up at it and say they could do better on a dyno and had to eat humble pie after!
All depends how you set it up and what you make it aim for.
One area where it doesn't really work well (neither does a dyno) is the very low throttle- rpm areas as the pulses in the exhaust mess with the readings a bit.
