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 The previous version was outdated and no longer supported.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

2011 TE449 Running well with factory EFI system - finally

Well, I'm glad you have an opinion, but you don't have all of the options.

First option is to just break it in, or take it past the 500 mile mark as Radar did and is happy with. Your next option is the BMW map#3 or Full Akropovic Titanium Map flashed onto your oem ecu, which you failed to mention and is clearly written in the Op's posting. You can also have your bike tuned by a dealership with the HST up to a +/-3 level. Do not adjust your TPS without either being hooked to the HST or an vom meter if you are experienced. If you have installed an aftermarket exhaust system that flows greater than the Husqvarna Akropovic special parts system, you may need a tuner or better yet, you can piggy back your map#2 or #3 with a Powercommander5/Bazazz and add precise ignition + fuel curves. You can further add a custom dyno session or add an Autotune.

If you have map#3 loaded with a stock exhaust system and are still having flame outs, you may have a different issue which needs to be addressed. If you have added an aftermarket exhaust like an FMF Powercore, etc. and you are still running lean, experiencing flame outs, then you will need to add more fuel in one of the methods listed above. Yes it costs money, this is not a free sport.

Also, I would appreciate it if you would refrain from spamming this thread all over the CH forum, especially to CH members who are looking for help with other issues such as their oil systems and not their EFI, my customers included.

My apologize here ...

Tinken is right, and i forgot the Details and how my Bike is Set up.



- Akropovic Muffler from day one Installed.......... Australia Standard !!............................................................Flame out's every ride.

- Plugs on the right spot and Oxy Sensor out. Standard at my Husky Dealer in Victoria.......................................Flame out's.

- Map 3 installed at ~ 250km. It did make the bike more responsive , ................................................................but didn't fix any flame outs.

- TPS Calibrated at the Dealership (Warranty) because Bike didn't start properly when Hot stalled..........................helped , but not with flame out's

- FMF Powercore Installed (~680km ) after it was brought to my attention here at CH.!!It's going to fix the flame outs........ .....No it did not at all.

- 680km INSTALLED ZIP TY Breather with the hose straight to the Air box. Run 1200ml Oil and got rid of the Oilspill. GREAT IMPROVEMENT !

- Break in Time and miles. After 2200 km since Sep 2013. all of us would think it's well ridden and broken in......................Flame outs every ride.

- with near 1000km , i installed a Ground Cable , just as mentioned here in CH..........................be honest, i cant really say it helped...........

- for all of you want to know how many km compare to ONE mile//// ... 680km ~ 405mi /////// 2200km ~ 1310 mi 1mile = 1.68km.

- For myself, i check in here quite often... probably because i was not totally happy with my bike. When i see a tread which makes sense to me as a Mechanic, i usually get on it right away.
But i am aware of, it might not help at all and i wasted some time.
But for the this mod so far.... it helped on my bike and 2 of my Friends here. Both have 2012's 449 and a 511.

Hope this helps and is enough Info for the Normal Trail Rider and Bike Enthusiast .


IF you feel not Confident to remove Butterfly you self or do any other mod's .... please visit your Dealer or Mechanic.

If you are a PRO rider, perhaps then you have to consider to buy some Electronic's.....




And if someone want's to Ban me now from CAFE HUSKY, feel free to do so.

I am on vacation next week, will do non-scientific test on this mod,
my bike is running very good, de-smogged, jumper, map 3, FMF, Pcv
with ziptys map, it is very fast, very responsive.
 
I do agree about the PCV, I installed ziptys map for FMF/stockairbox,
bike ran best ever. still had a few stalls/flameouts snapping throttle
at low RPM. adjusted up 5% at 1500, all the way to 3000 and have not
had an issue since once bike is properly warmed up. Very Happy.
 
Tinken... Have you tried 2nd FBW butterfly removal? If so...

1. What was your impression of the effect?
2. What is/are the potential negative effect(s), (other than possible damage to sensitive electronics)?
 
If you read through the thread its quite clear.

Potential damage to the fbw motor if it were to freak out for some reason.

Increased engine braking.

More abrupt throttle response/engine response.

More abrupt power delivery.


You all should wait about a week and I will give a very good report of the secondary butterfly removal on my converted supermoto bike.

I have the power commander and auto tune which will definitely help as to adjust for any fueling issues that arise.
 
I just got back from a short ride on mine. All tight single track stuff. Bike was good, not too snappy or anything. Not a whole lot different than before. Just no dead throttle.
 
Not to be argumentative.... but... has anyone (Tinken or anyone else) actually done the FBW butterfly removal modification and found it to be a problem?
ALSO...
Has anyone actually DONE the butterfly stud removal and found IT to be a problem?

huskyluv: Wait a WEEK! That's a long time... What if the zombie apocalypse comes and I have a hanging idle?
 
Tinken said:
^^ What Huskylove said. I am not sure of the long term effects. I know that fooling with the efi unit can be disastrous, we destroyed mine and had to replace it. I have quick, snappy, smooth power with both butterflies installed so I know it's not some kind of engineering failure. I'd just wait and see what happens before jumping the bandwagon here. :)

how you destroyed EFI??? o.O
 
I have PCV, map 3, race pipe etc. but still get the hanging throttle regularly - will grinding off the stub fix this issue ?

Yes, but sometimes it is caused by the bypass air screw being out too far. If I wind mine out too far the idle hangs for a few seconds before it comes down. So check the screw first, if not, then yes grind the stub off
 
thanks everyone - this is an interesting discussion
I would prefer not to remove FBW butterfly or grind the stub off.
The bike is awesome now that's its run in and pops 3rd gear wheelies under throttle alone.
I just need to sort the hanging throttle issue so will check the idle screw which I haven't touched since the dyno tune and also for air leaks

where is the vacuum nipple Tinken - is it prone to leak ?

The arrow in the image below points to the idle screw. Below that you can see the brass nipple capped off. I have since removed the vacuum plug and replaced with a solid bolt. The vacuum caps tend to leak and cause idle hangs. You may want to lower your idle down in 1/8th turn increments. If this causes stalling, increase fuel ratios in the beginning of your map to compensate (1500-2000 rpm.
