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 The previous version was outdated and no longer supported.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

PC5 + Autotune + cool mufflers happening soon, will keep you posted.

I guess reading between both yours and Chris's comments i'm now wandering how does one begin to relate/translate a/f ratio's?

with the autotune and it O2 sensor installed you predetermine a air fuel ratio you would like and it works its ass off constantly to provide that. Like Chris says above 13.2 is a good starting point. You can then modify the maps it creates if you like. It is very cool and the high end solution for sure.
 
I need to write a summary and details about the PCV & AT at some point, but for the time being:
Creating a map on the dynamometer is almost always done under acceleration (only).
That means some 'cells' will never be created in the maps on a dynamometer - the ones at higher rpms at small throttle openings for instance (going high rpms, then close throttle to slow down).
The Auto tune fills in the missing cells.
On the other hand, some cells are never populated by the AT - the AT can only fill in the cells where the bike is ridden i.e. personally I would never be WFO at Max rpm, but other people obviously would.
There are a lot of different theories about what approach to take, the above is my opinion.

Maybe check out dynojets video library for more info? AT-200 (single channel) would be the one to use for TR650s. Here is an AT intro.

Chris - Motosportz and Coffee, thank you all for your personal input and experience with PCV. It really helps a novice cut through the mine field. I think it'll be a PB for a while longer, until things get worked out with the idle issue. Also hoping at some point to see an after market pipe. Seems for me that would be a point to make the upgrade.
