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 The previous version was outdated and no longer supported.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

Difference between ECU Reflash and PCV?

To help me understand some of the threads here:

What does an ECU Reflash do / change versus a PCV? Can a PCV be adjusted to do what a reflash will do, and then more?

Thanks.
 
I'm just getting up to speed on all these things myself, but I know the PCV will piggy back off the map in the ECU. So the PC is a slave to the ECU, in a sense, but the PC allows you to readjust the fuel on the entire range of your throttle on top of the base map. It's recommended to use the "race map 3" map from BMW, as this corrects the lean fuel mixtures that help to keep the bikes Within regulations. With proper mapping and PC tuning, it's a night and day difference. Makes the bike a lot different, to say the least.
 
Thanks. I assume the ECU will also control timing - but I don't know. Will the PCV also allow for timing adjustments?
 
Yes, the PCV goes in line with the injector, TPS, and spark coil as well as tapping into the crank sensor, the best bang for the buck is to flash the ECU with map 3 and add a PCV.

Huskynoobee's 2011 449 could not accept map #3, so his powercommander does the work of both.

The ecu re-flash is a very broad step up in fuel mapping and ignition curve. For $40 bucks, it's a great deal. The Powercommander piggybacks on top of the ecu. Yes, the Powercommander can improve the fueling and timing without an ecu remap, but it takes a little more adjusting since my maps are based upon systems that already have map 3 installed.
 
on the 13/14 310, the kit Dynojet made for me... The only missing thing was they could not give me a PCV w/ignition timing adjustment so if the ECU maps have ignition changes, it's wise to have Map 3 on this machine as well. Then again I don't have map and timing data for the ECU.

I find that really odd since your efi system is the same as that on a 449. I've seen your bike and it runs so smooth as is, but I'm sure if you really wanted ignition timing, it could be done.

They did use an existing Husky PCV, though had tried others to get the functionality. They had issues trying to make it work. No big deal. Runs great and have some latitude to tune.
 
Yea, I think you're fine. I commented to Jeremy about how smooth you were at Gorman. The map upgrades on the 310's are a good step in the right direction. The pcv allows even more refinement towards a smooth running system.

This is interesting, I didn't realize there were timing changes between the ECU maps. I'm running a PCV w/ AT working of the Burson map (timing as well), on top of a locked 2011 TE449 ECU. Should I zero out the timing changes? Or some other tweaks you'd recommend?
 
No, I wouldn't zero them out. We're actually running a new timing map that is more advanced than the Burson map.
