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 The previous version was outdated and no longer supported.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

De-cat question, TE449

Martillo Dave

Husqvarna
A Class
I think I'm ready to de-cat my stock muffler (2013 TE449), and have seen the links/posts showing how (thank you!).
My question is this: Is it going to mess up my tuning? The bike is running great right now, I have never had any problems with it flaming out, stalling, whatever. I don't have any cash for other stuff like the PCV, etc. I'd like to cool off the muffler and get a little more air to the engine, but don't want to create a problem that requires more $ and more tinkering. Thanks!
 
Are you running RaceMap II or III? If you are, de-cating it will make it run better.
 
When I disconnected the smog stuff the bike went right into Race Map II.
So you're saying that de-catting won't cause flame outs, stalls etc.? What's causing those things on these bikes? Thanks.

The cause of the flameouts can be one/or mixture of the following: secondary butterfly, factory mapping and you might need to reset tps and/or up the voltage on your TPS.

If your not going to run a PCV send your ECU to zipty racing so they can install the 3rd set of Maps everyone calls RaceMap lll. This will really wake your bike up and cost around $50.

If your running Racemap II you should definitely de-cat. That map is intended for a open exhaust.

I have a de-catted stock exhaust and FMF if you want to try it out. PM me
 
Thanks for the offer DJay (sorry, haven't figured out how to PM :confused:) . Think I'll start with the de-cat. Really can't afford a new pipe for the bike, and understand that the FMF needs other "stuff" to make it acceptable in California. I appreciate your help!
 
My question is this: Is it going to mess up my tuning?
Probably.

Note: When cutting the cat out. Be really careful not to go too close to the mid pipe. I went 2 mm too close (too far forward with respect to the front of the bike) on my cut and not only did the cat come out, so did the mid pipe. I never did get the thing welded back together correctly. I was able to hack it back together, but it always leaked.
 
BTW, when they say race map III they are talking about the factory akrapovic flash. You have to take it to your dealer and have them do it. AND, it highly recommended.

Or mail it to Zipty. Had it shipped to and from in 3-4 days.

I'm going to go against the grain here a little bit. but first some background: my kid has a '12 te511 that is a frikken rocketship (fmf q4, some zipty stuff, and jd or pc5- crs). it's actually too fast and hard-hitting for me, and one of the biggest reason i bought my '14 310r.

so that being said: if it's running to your liking, hell- leave it alone. or take dj up on his exhaust offer first so you can test the waters, so to speak.

good luck.

You can also do a map switch on the PCV or the Stock ECU for mild and wild.

I just PM'ed you.

DMV doesn't look at them if that's what you are concerned with. Try to find a used FMF, even if it's beat up a bit, it'll be worlds better than the decatted stock. I had both on my bike. The FMF made a difference you could feel. Should be able to find a used JD tuner which will help with fueling with either decat or fmf. Also, the butterfly is a good mod that couldn't be any easier to do. Also grid off the thing on the throttle pulley. It's also listed in DM's butterfly thread (or check out the facebook group). Both are free, and make a difference.
The run on caused by the tab on the throttle pulley is dangerous. Don't ask me how I know.
