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 The previous version was outdated and no longer supported.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

2012 TE310, how to make it run well

J

James ODay

Husqvarna
A Class
First off, I have searched on this and there are alot of threads, and I have read them, but it's all pretty confusing, power up kit, remap, TCX ECU 12 port injector, etc, etc. There doesn't seem to be any dealers around here (metro Denver) that know about this stuff.

My 2012 TE310 flames out alot, doesn't really start well, runs OK once it's running, but could use a little more power. Has done this since I bought it with about 10 hrs on it. The dealer I bought it from warmed it up real well before showing it to me. I'm not racing, just taking in the scenery on the trails.

I understand the power up kit includes an O2 sensor plug, a connector plug where the O2 sensor plugged in, a TCX air filter cage, and removal of the cat. Something about a different velocity stack, but I'm not sure about that. Would this make it run better, and does it need to be remapped if this is done? From the reading I have done the fuel injection mapping is too lean and that is a big part of the problem.

Then there is the different ECU and injector and from what I have read that transforms the bike. But I think a better first step would be to do the power up thing.

The bike is stock right now with the exception that I have removed the evap canister.

So am I right in pursuing the power up kit? Seems like it's something I could do easily and fairly cheap and get some good bang for my buck.
 
I decided to power up my 14' incrementally to see what needed to be done and what was going beyond what a trail rider needs. I ordered the TXC Velocity Stack ($25) and TXC Air Filter Frame ($3) to start. This transformed the bike. Try that and see what you think. I'm doing CAT removal too cause its free and easy. After you do those, see if it suits your needs. Phase 2 could be remap (quoted $75 from dealer or send ECU to Zipty and they can do it for I heard $40). I believe you have to do something with the O2 on the 12' mine just doesnt use it, Tinken can tell you, call Zipty and ask or PM him. You may not need to touch it unless you remap. In my opinion, do Vstack, filter frame, cat removal and assess performance.

Change out the stock air filter cage with the unrestricted one, remove the cat from the mid-pipe, remove the lambda sensor from the header and plug the bung, and install the lambda sensor resistor plug in place of the sensor in the wiring harness. You will most likely also want to change the gearing. Most folks seem to be happy with between a 45 and 50 tooth rear sprocket depending on the type of riding you do. I like the 50. If this does not do it for you, then take the next step and install the TXC injector and ECU if you can still find them.
 
I bought my 07te450 with 1500km and it went ok on test ride but its taken a year to get it right!
This might be totally unrelated to yours but my hard to start issues were solved by adjusting shims back to spec. I got a mechanic to check and he said they were fine but I had a go myself and even though they were within limits when I made them spot on the bike loved me for it. It really is so damn easy to do too, just don't drop a shim then push it through a little oil drain hole like I did!!!
 
Of course I am biased because I own a 2012 TE310, but IMO, the 2012 TE310 is the best 310 out there once converted to the TXC ECU and injector. It was the last year prior to BMW redesigning the valves, head and fuel injection. I rode a well tweaked 2014 TXC 310 with all the BMW redhead F1 racing inspired yadayada stuff and afterwards I realized that I already owned the best 310 model Husky had produced. Of course this is my opinion and those who haven't ridden both will argue against it but that is what forums are all about right? Moral of the story is, uncork your bike and ride the wheels off of it. Enjoy!:thumbsup:

I agree. I'm going to have the ZipTy mods done just to make Reveille jealous, though.

Call Big D Motorsports in Woodland Park, CO. I'm assuming you used Grand Prix but Big D is much better in my opinion.
 
Thanks all for the tips people, I really appreciate it. I think I'll go the uncorking rout with the velocity stack, air filter mod remove cat o2 sensor etc and see what that does. I got quotes on all the parts except velocity stack from Halls. Not expensive but some are backordered. It does not sound like I have to remap if I do this, but I suspect I will want to. I also suspect I'll want to change sprockets at some point too.

Thanks for the tip on Big D. I bought the bike from GP but they don't seem to know too much about these issues, but to be fair last time I talked to them about it the guy that maybe was supposed to know was not there that day, so maybe I'll give them another try.

No velocity stack on the 2012, and as far as I know you cannot remap the Mikuni ECU. You might want to check with BMP. They might have what you need in stock.
 
Another option on your 2012 is to add the 12 hole injector and then use the JD tuner instead of swapping to a TXC ECU. Cost is about the same but I think you end up with more tunability with the JD programmer. Just more food for thought to really confuse you...;)
 
Yes that further clouds the issue but it's still good input. I'll investigate the JD tuner. Ideally everything I do I could do myself as it's kind of fun to fiddle with these things.

For anyone who cares, the part numbers I was able to come up with for the power up/uncork/whatever you call it are as follows:

O2 sensor Bung plug: 8000H7302
O2 sensor connector: 8000A6750 (Anybody know the resistance?)
TCX air filter cage: 800069549

Couldn't find a part for a different velocity stack, the parts fiche shows a 'union' for the TE, P/N 8000H1522 but not one for the TCX, so I don't know what it uses. I think somebody said in one of the posts above it does not use one, so that maybe is not an option.

And I have no idea what CO points and Ibeat is.

Just call Bill's Motorcycle's Plus (BMP) at (503)585-1153, ask for Bryon, and tell him you need the power up kit for your 2012 TE310. He'll take good care of you. 2012 does not have a velocity stack.

I have a spare ECU for a 2012 TXC310 with the 12pt injector if you need one.

Buy a 12 injector for $90 and you are good to go.
 
CO 1, 2, and 3 relate to fuel at low, mid, and full throttle. 100% is base. Adjustments will likely be small with the TXC ECU and 12 pt. injector. Maybe you will see 110, 105, 100 as best adjustments but it will likely run OK aat 100% on all 3 CO points. iBeat is the software that allows adjustment and also identifies error codes and can reset TPS (throttle position sensor) pretty important to get ignition advance accurate and good idle etc.. Most dealers have it. It's about a $250 item I think.
 
I too have been thinking about getting the TXC injector and ECU but am afraid to install it and have to reset the TPS b/c there are no dealers within 3 hours of me. Has anyone just put the 12 port injector in and left the stock ECU??

I think we need to start a seperate CO thread for us 2011-2012 mod guys. I say that because I recently aquired the iBeat setup and started playing with the CO's a bit. It may be nice to put our thoughts and data together.
