I just installed the race ECM along with a Jardine exhaust & K&N filter. I need to reset my TPS but can't find any other ways of doing it aside from going to the dealer and getting wacked $102.00 + shop fees & taxes. Can anyone help me out? The HD service dept. tells me it can be done with a digital volt ohm meter but the they won't give up the directions on how to do it. Any input would be greatly appreciated. | ||

It should NOT cost $102. It only takes a few minutes. | ||

yea well my dealer wacked me $305 for the first oil change...never makin that mistake again | ||

Local shop charges 30$ + tax (1/2 hour labor). it takes 15 mins to do but they charge a minimum half hour. Sounds like you should call them back and make sure they quoted you the right price, and if so ask why it's so much when it's a HALF-HOUR procedure. | ||

TPS reset costs $70.25 at the Woodstock NY dealer. I guess their gouging customers while they can, since their dropping the buell line next month. First Maroneys in Newburgh, then Iron Block in Adams, now Woodstock! Buell dealers in upstate NY are dropping like flies! When all the buell dealers are gone where will parts be had? | ||

I take it the equipment to do it is expensive? What do you need? | ||
| Frausty12r |
about 270$ get a Dongle and the required software from Daves. takes about 10 mins to do once you've done it a few times. Technoresearch also sells the software/cable system for about 290$ | ||
| Hd_xb12r |
So your saying I have to purchase both the cable and software for a total of $560.00 in order to do it myself? | ||
| Daves |
No, I sell the Technoresearch system. List is 285.00 Badweb price is 256.50 All you need is a laptop. They should only be charging about 25-30.00 to reset your TPS at the dealership. BTW the first "oil change" is alot more than just that if they are actually doing everything on the list. 305.00 is still too much but to think the 1000 mile service is just an oil change is not correct. | ||

I paid $32 for a TPS reset last week. $102 is a real steal!!! | ||
| Frausty12r |
Just as dave said, Sorry for the confusion, the packages include the connection cable AND the software. You buy it once, 10 tps resets later it's paid for. Hell you know people with buells and they need it done, you could make a profit after a few $20 tps resets for them. | ||

Get the latest updates from technoresearch. Its a little quirky but it does the trick. | ||
| Hd_xb12r |
How do I get one from you Dave? | ||
| Frausty12r |
Pm him =) | ||

Kinda off topic, but this seems a good place to ask. Is the TPS reset a normal maintenance item, or just if you add performance mods? Thanks | ||

There are regular intervals for the TPS reset as well as if you change ECMs or do any significant modifications to the bike. Adding just a K&N is not significant....adding a Jardine(or any other fairly open exhaust), removing the airbox restrictions completely, etc. may be significant enough to require it. The TPS reset is based on a sensor noting what the throttle position is for the computer to use. Over time what the sensor "sees" can change because it is looking at the behavior of mechanical parts. When this happens the signal from the sensor to the computer can change making the bike run differently. There are intervals in the Service Manual indicating how often the TPS should be reset to ensure relatively consistent behavior. If you change ECMs (i.e. install Race ECM) you should get the TPS reset. The bike may run okay when it is installed (if so then you were lucky) but the computer has been changed...and everything really should be calibrated again so a TPS reset is part of this. | ||

Every 10k miles is the scheduled interval for TPS reset via the m.o.m. This is in part as lovematt stated, due to the fact it's an electrical device, "seeing" a mechanical parts movement. Coupled with the fact the motor shakes can sometimes move the orientation of the TPS assembly, so even though the ECM "thinks" the throttle body's butterfly is closed, as the TPS is telling it, it may in fact not be closed. | ||

I'm a little confused. What does the TPS have to do with the muffler? I've never heard of anyone doing this on fuel injected cars, i.e. Corvettes with aftermarket exhaust. My understanding of TPS function is that is tells the ECM what the throttle position is. That's all. The ECM also takes inputs from the 02 sensor (fuel/air mix) and crank sensor (RPM) and determines how much fuel to dump. On auto engines there's also inputs for temperature and air flow/density, etc.. Can someone explain this whole thing? | ||

I'm a little confused. What does the TPS have to do with the muffler? The installation of his New ECM requires the TPS reset to 'calibrate it' if I understand correctly. Swapping of mufflers only would not require it. | ||
| Madsx |
For just a muffler change it may not be necessary. Unless it runs really crappy. Sorry a little late. What chainsaw said. (Message edited by madsx on August 14, 2005) | ||

It is very likely muffler only would not require a reset...however other things change about the motor when it is opened up. Restrictions at idle are reduced as well as at other throttle positions which could make it run differently (possibly worse). The motor shaking could be another factor...I noted my seems to shake more after adding a Drummer and cutting everything the top portion of the air filter cover away (the part under what you see normally). I imagine all of this is a factor in this sensor to mechanical parts linkup. I think this also has to be done for cars but I don't believe the intervals are nearly as short...I know some buddies of mine running computer controlled cars have mentioned doing a TPS reset on them after 15,000 - 20,000 miles seems to make the idle smoother and throttle response noticably better. But these cars are a bit pumped up though... | ||

Keep in mind you have to adjust the hot idle after a TPS reset, otherwise your idle may be too high or too low. If I'm doind a TPS reset only, I reset the TPS, start the bike after hooking up to evacuation system, get to between 280 & 320 degrees, and set hot idle to around 1100 RPM. That's where some of the labor goes, getting to operating temperature & test riding. It is a part of normal maintanence, every 10,000 miles & should be done at those service intervals, so a test ride is part of that service, along with the TPS reset. | ||

1-866-757-1651 ask for Dave in the sales dept I'll be back to work on Tuesday and I have the Techno stuff in stock for you. Thanks Dave | ||

Yup in cars the TPS can be reset with a good ohmmeter. The resistance for the individual tps can be found on forums all over for varying cars. Pretty much same procedure, only you don't need to hook it up to a software/cable system to "See" the degrees. just twist it on the adjusters until the resistances matches what the "zero" resistance is. Wonder if this could be done on the buells *smile* Only thing, the TPS is harder to get to on our bikes than most cars. *bummer* | ||

Thanks Daves ,I'll give you a call in tomarrow. | ||

Frausty do you know if it can be done with a ohm meter? This would save me a lot of cash and ohm meters are very readily available where I work too. | ||
| Frausty_void |
B12burner, Dunno man not too familiar with the tps on the HD's and Buells. I'm sure all it is, is a potentiometer that sends a varying resistance to the cpu and that gets translated into degrees. What resistance equals what degree, I have no idea. | ||

XB12Burner, No you cannot perform a "TPS Reset" on your Buell using an ohm meter on account of what that procedure entails is not setting anything on the TPS itself, what the procedure does is reflash the ECM with the TPS voltage corresponding to the throttle closed (not even at idle, fully closed) position. The procedure SHOULD be called "ECM Racalibration for TPS voltage." Nothing screams poor quality more than an egregiously inaccurate technical description of a common maintenance procedure. The factory really should revise their nomenclature. (Message edited by blake on August 18, 2005) | ||

Blake... I love it "Engineer Speak". I put it in an e-mail and fwded it around the office. Every day we take in and process a lot of information. As engineers we sometimes communicate our thoughts aloud so others will know why were so frustrated. I recently was working on a project and was reading thru some technical maintenance procedures. This was my thought but another engineer communicated his thoughts first by saying this: "Nothing screams poor quality more than an egregiously inaccurate technical description of a common maintenance procedure. The factory really should revise their nomenclature." If you’re an engineer... laugh away... for all the rest just keep scratching your head and mark that notch on the post about not being able to understand their sense of humor. Good day! | ||

Well, since our XB's are so maintenance-friendly, how about a "TPS Reset Day" (you know, instead of a "Maintenance Day"!). Sure would help cover the cost of the TechnoResearch system. | ||

Thanks for feeling my pain brothers. ![: ]](http://www.badweatherbikers.com/buell/clipart/proud.gif) | ||

Looks like it will be a VDSTS for me then. Thanks for the help! | ||

My local HD dealer (not a Buell dealer either)charged $13.00 to check the TPS. It was fine. Stock bike. |
