  • 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 The previous version was outdated and no longer supported.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 Dyno results

Husqvarna
A Class
Just had my 2001 Te449 dyno tuned with Power Commander V. Had a JD Tuner, which was good and great value. Managed to get the worst of the low end stalling out of it, but wasn't convinced I was getting all I could from the bike (user's problem not the tuner). So thought I'd go for the dyno tuned Power Commander (not a cheap option).
Bike is standard with the race map on and an FMF Powercore 4 tail pipe.

The green graph is the zero map with db killer installed. Doesn't really show the horrible behaviour off idle, but you can see a big dip in performance at around 5500rpm.

The blue graph is remapped map with db killer installed.

The red graph is remapped with the db killer out.

Not insignificant difference with the db killer in although I was surprised to see it actually performing better at higher revs, guess the bike needs some back pressure?

Anyway, on balance the db killer stays because the bike is so loud with out it (120db compared to 114db in).

Happy with the improvement. Rips at higher revs, much smoother with heaps better throttle response across the rev range, but especially down low.

Happy to share maps if anyone has a similar set up (I think Dyno jet currently only provides a map for the 2010 TE450 - my bike ran worse with that in than the zero map....)

I've got the exact same setup and experience the same drop in power through the midrange. How,exactly, do you share a map?
 
Great post, love seeing the improvement with addition of back pressure, that is balancing the air/gas charge in the chamber for more power, instead of the charge dribbling away before combustion.

If you've got the Power commander I can just email or post up the map file and you can load it onto yours.
 
Wow, that is a huge difference between the base and the modded map!

Regarding the difference between the plugged and unplugged exhaust: it's possible that the pipe is tuned a little lower than the cams / intake length, but the dB Killer is damping those unhelpful pipe resonances. Dirt bikes are a bit of a balancing act re. peak power vs. midrange, but that red curve fills in the midrange nicely and finds some useful overrev. Factory settings are horrible - not only do they aim lean for emissions, it's common to richen a certain spot to help with the noise test (depending the test spec for your part of the world).

It might be just me, but as an old guy I find the thought of ragging a 450 single at 9000 rpm a bit brutal! :lol:
 
Yeah, I'm kind of the same re high revs, but realised today how little I'd been using the peak power on the dirt. The only place I've been able to ride is reasonably tight hilly single track with no real areas to wind it out. But I rode it on the road today with supermoto wheels and man there's some pretty good power around that 8500 rpm mark. Will definitely be holding first and second gear a little longer on the dirt in future.....
 
Schoops,do you think your custom map would work with the standard acropovic silencer and race map 2 on my 2011 TE449,iff i purchased the powercommander 5?

Couldn't be certain, but assuming the akro is more free flowing than the big old OEM stink box we get here (i.e. is closer to the FMF) and that you have the same standard map as I had (i.e Husky don't tune it for the akro better) then my guess is you'd see an improvement. You could try my map as a starting point, but if you invest in the power commander you might as well get it customed dyno tuned at some point to fully match your bike.

BTW I see Bazzaz now does a self mapping unit for the 2011/2012 TC449. Has the O2 sensor included and looks like it's the right size to screw straight onto a Husky - Power Commander has an add on sensor, but it's additional cost and a different thread size so you have to weld on a new threaded sleeve to your header). You'd have to check with the manufacturer, but I would assume you can use it on the TE. If I started over I'd take a closer look at it - it looks competitive on price.

hi schoops i would like a copy of your map if i may!pcv on the way today.

Hey wallace, have attached the map I had done with the Db killer out (can't find the other one atm). Hope it at least works as a good starting point. Let me know if you have any hassles with the file.

Just got my TE off the boat in Sydney on Friday after returning to Australia from the US on posting. Haven't seen it for 4 months! Started first time and is running well, can't wait to get it rego'd and hit the local trails.

hi schoops i was able to load your map into pcv.i have i couple questions,how is your bike geared?also my dealer adjusted the map in my stock computere will that mess me up?my bike rips with his map i just get that stalling in tight woods riding after its warm.pcv would not send the map i got from there sight for my bike(stock exhaust,map 2) but yours did?what did you do in us?thank you for your help!!!

Hi Wallace, glad the map worked. I've got my supermoto kit on now, which has a 44 tooth rear and the standard front. Now it's running we'll I wouldn't mind going two or three teeth smaller on the rear for the road as I think it will pull it ok. I'm assuming the PCV settings will adjust from whatever your base map settings are so It's possible if your base map has been changed you may end up somewhere slightly different to me but it sounds like you're heading in the right direction. IMHO if you've gone to the expense and effort of installing the PCV you might as well go the next step and get it tuned on the dyno then you'll know exactly where you're at and have it tuned just right for your bike. My low speed stalling issue has basically gone, I found some real power and smoothed out the power curve. Really did transform the bike. I'm not sure if PC has updated their map for the TE, but when I installed mine the map on their site was for the pre-BMW type motor so basically not of any use for a 2011 TE. I was working for Defence in our embassy in DC - we had a great time, but good to be 'home' too.
