With my bike (09TE450 PW'd-up) I wonder if I am finding its limits or if it needs adjustment- low end-throttle response is weaker than I expected- for technical riding. Please, Tell me how your bike is running before and after Ibeat adjustments and/or getting a Power commander....what was corrected and what the bike runs like now....
There have been some happy 2008 450 owners, it sounds like something may not be working right from you description. How far to get to an ibeat?
There's a possibility they set the TPS wrong or even that they just set the FB1,2,3 at 100% and called it good. It does sound like the adjustment needed may be minor as you've narrowed it down to low end response. Maybe the FB1 needs a bit more. My settings turned out to be 100.6, 100, 100. I also had a new throttle tube put (ball bearing) on that is a bit smoother and has less vibration.
Thanks man, Well I think I do need to get it on the I/beat- But that can't do everything either...gonna try to coordinate that with the dealer tomorrow. I fear I need to have it hooked up to the Ibeat- then get a power commander- then Maybe? I just never hear anyone say, "hey it ran like crap- took it in had Ibeat adjustment and wow its perfect" I never hear anyone say it runs perfect ever... even after buying a Power Commander. I used to read about guys with carbs say "my jetting is perfect" (like me) - People seam happy with EFI, if it isn't dying or completely falling on its face. I gotta say- outa the box its pretty good compared to outa the box on a carbed bike- but I don't know what it takes to get it where I want it- and I don't see a lot of feedback. by the way my bike is 100db at 4100rpms with the spark arrestor in- so I need to get the db killer to hopefully get <96db, that going to kill my power more or give me more down low..?? Sorry, I am always optimistic and don't get a lot of input on threads so I guess I am trying pessimistic
If I had an efi bike I can assure you much information would be flowing, I do not have one and will not be getting one in the near future. If there were time (and there is not) I would try to get with people and experiment on their bike with an ibeat & power commander. Maybe when someone that I know well gets an efi bike that may happen.
If you stick a DB killer in that restricts the exhaust system somewhat the fuel metering should be leaned out to compensate for reduced flow. Therefore if you are currently running rich, the bike will be excessively rich after installation of the DB killer. If the engine is currently running lean, the addition of a DB killer may assist with proper fuel metering. I've read many posts of 08 Husky owners that are a faced with poor fuel metering and it puzzles me to death since my 08 510 seems spot on and I can't imagine how someone could even get close to utilizing all the power this bike puts down. The problem I'm faced with is finding a suitable tire that can find enough traction while not digging trenches besides looking for pavement g's. Everytime I ride this bike and crank it WOT thru the gears it still provides immense thrills and fear at the same time. Have you been able to compare your bike to another TE450 (drag racing) and note the differences in acceleration? What type of air filter oil do you use and how frequently do you clean your air filter? Do you know that it takes 20 or 30 miles of hard throttling to ensure that the air filter is flowing air properly after re-oiling and not choking your air intake? Are you using ethynol fuel? Have you check the valve clearance? Brake pads dragging? Chain oiled? Wheel bearings OK? Verified that the throttle is going WOT?
Yea,mines eating rear tires too- I don't have issues at speed- just in technical stuff. I started this thread to find out- what people's bikes ran like before and after getting tuned- what are the symptoms of badly tuned efi and what are the solutions- TPS, FB adjustment, Power Commander. There are various states of tune that a bike can be in ranging from: not running, to barely running, to running "good", to having small problem areas, to perfect. My personal state of tune as I am learning my bike was that it seemed lean on top, it also seamed weak off the bottom, slow speed throttle response, Loft the front over logs- stuff. I wondered is this fixable or am I finding the limits to its low end power... Yesterday I had the bike hooked up to the Ibeat. They adjusted the TPS and changed the FB setting a little richer. In a few hours I am headed to Wabeno to set up Dualsport trail-WDSR, Ride for Research, and ride the Pearson- TuffEnough enduro on sunday. So I will have an idea on the new state of tune after this weekend. I probably have to gear it down some- to get the low end power needed- I road it at the dealer'king lot and it seamed better- in that area but didn't do quite what I wanted it to. Gearing is probably key. I like the stock gearin 13/47 for mixxed riding- but in tight single track probably want 13/50
Good luck there. I will say I kind of like the original 13/50 gearing for the slow speed control. 08 TE250
I rented the Ibeat kit from a TT member and performed TPS/FB1 adjustments till it was running to my liking. I can say after tweaking with the Ibeat I was able to fix poor running issues at low rpm (flame out, surging) and yes it's much better now. I have the PC (bought it before the Ibeat renting), but have not installed it yet. When I do put it in I will have it Dyno'ed for max MPG/Performance. I have yet to hear anyone say after a PC / Dyno, they were not impressed / satisfied. I settled on a FB1 setting of 96. 08 TE510
I have not given it a fair test yet, but I would have to say MPG went up. I will try and get some real world results posted, before I go the Dyno Shop.
09 te 510 My bike seems super slugish at low RPMs and it starts to pick up around 5000 RPM. Im in the same boat you are in I was expecting way more power and torque I hope tuning it will make all the difference
I have just got my TE310 on the 27/04/09 and have done 300km and a few mod on my bike. - remove and fix new air filter housing(28/04/09) (bike move off and stall a few time) - remove diffuser(29/04/09) (better but lot of poping sound after that i fix back the diffuser) - remove throttle stop(13/05/09 it was remove when i got the bike) (still stall on low speed and when moving off) -remove catalyst(15/05/09) (wost more poping sound and more stalling) going to fix it back tomorrow. Please help me on this. thanks guys. Matthew from Singapore
Matthew, you need to find a dealer of person with the iBeat ™ software that will set your Throttle Position Sensor and adjust the Fuel mix at 3 points on the acceleration curve (FB1, FB2, and FB3) Mostly the TPS and FB1 are the important settings. Without the software I don't think you can get it to run right.
I just bought a 09 sm510, do you guys think I can get the bike to run right with the powercommander and a map instead of the iBeat? Im pretty sure with the PC III I can set the TPS as well.
This is exactly the type of question that needs answering in crystal clear detail. What do the makers of Power Commander say?
I think you can. I have control over every aspect of the FI, even TPS closed and open settings. You also have more adjust ability than you do with the iBeat, based on what's in the Husky shop manual. There's enough that I'm considering putting the O2 sensor back in and seeing what sort of performance I can achieve with with a "closed loop", or try a PC V with auto adjust.
PC V isnt out yet. The Powercammander rep told me this "We are only going to make and test the PC5 on 2009 models. We are trying to locate a husky to do testing with since we have no local dealership here. If you know someone in the Las Vegas area have them contact us and we give them a Free PC5 if we can borrow their bike to develop the PC5 for it". Let me know if you have any other questions. Thanks.
