help with ecmspy

[dustin_usmc1]

I have an 08 xb12s with the airbox delete k&n air filter, and drummer exhaust. The bike is running hot and feels like i have lost pwer and want to tune it with ecm spy. trouble is i need to reset the tps and cannot locate the idle adjust screw. everyone has said that it is located on the left front between the air scoop and the engine, but it is not. please help, and thanks in advance.

[xtremelow]

There should be an adjuster cable (screw) that goes to the location you mentioned. It isnt necessarily a screw rather a remote located cable that allows adjustments on the fly.

You may have to remove the scoop to be able to see it since it may have slide back behind the scoop.

[dustin_usmc1]

I removed the scopp and still nothing.

[xtremelow]

If you look at the throttle there should be an extra cable that goes to a round style knob.

Hell maybe the 08 doesnt have that, in that case I wouldnt know.

[GatorBuell]

No the 08+ does not have the idle adjustment.

[dustin_usmc1]

then how do i reset the tps?

[Stevenc150]

'08+ TPS Reset Procedure:

- Turn on the key.

- Set the kill switch to the run position.

- Don’t start the engine. Rotate the throttle from fully closed (gently forced closed) to fully open (gently held open), and then back again to closed (gently forced closed).

- Repeat 3 times. Hold each position (fully open, fully closed) for 1 full second.

- Turn the key off and on.

Look there I was completely off[down]


Now I know for next time:)

[jakexb12r]

what does the tps reset do?

[Stevenc150]

Throttle Position Sensor reset. The TPS being off just a little will affect the idle and low end more so than the top end. Idle will be a bit rough and the bike will have a tendency to sputter and cough a bit down low. When it's off by more than just a little, it doesn't run right anywhere. Also, anytime you do a major mod, such as Airbox delete, new exhaust can, etc. it's recommended doing a TPS reset. Service manual suggests it at 10K mile intervals I believe.

[dustin_usmc1]

this is the only process to reset the tps? sorry i feel like and idiot here entering a video game cheet code or something. is it still possible to tune my bike(08) with ecmspy, or have i wasted my money on a cable that is useless to me?

[Stevenc150]

The cable, along with ECMSpy, can be used on the +08 bikes to adjust your maps, but the numbers have to be input manually instead of re-flashing like the older ECM's. But I suggest getting the specifics of the procedure by talking with Mike @ Xopti or someone of the like.

[taylor]

during the( Turn the ignition key to Off/On/Off/On/Off in succession to complete the procedure).. do let the pump come on each time? or do turn the key fast so it does nothing?

[Lando]

yeah, what taylor said.....

[taylor]

come on guys,someone here has to know how to do a TPS reset on a 2008

[Tork]

Stevenc150 pretty much already gave the solution, although the info I found says that you only need to toggle the key off/on once.

To reset an 08+ Buell, do the following:
1. Turn on the key.
2. Set the kill switch to the run position.
3. Don’t start the engine. Rotate the throttle from fully closed (gently forced closed) to fully
open (gently held open), and then back again to closed (gently forced closed).
4. Repeat 3 times. Hold each position (fully open, fully closed) for 1 full second.
5. Turn the key off and on (only once, not repeatedly).

Google is your friend. Took me 15 seconds to search and find this.

[dave_xb12r]

you could have just scrolled up a few posts

[xtremelow]

damn you guys are to funny. [mad] some times the best thing to do is open your eyes and or read from the beginning.

[taylor]

i guess you guys didnt read the whole post then. my question was very easy to figure out. i was asking if i had to turn the key three times fast or three times slow letting the pump and intruments turn on. although tork was being abit of a "smart ass" [smirk] he atleast undersud the question.

[dave_xb12r]

Ohhhh that makes more sense. Sorry....

[daponik]

Just got a new Jardine exhaust. Do I do this TPS reset before or after I do the "learn-in" ride?

[Stevenc150]

Do I do this TPS reset before or after I do the "learn-in" ride? Before

[drunk_uncle]

Holy cow that thing really works. I have been having some hiccuping at low rpm and small throttle imputs. I did the TPS reset and the problems went away.

[RedShift42]

Would someone please clarify the TPS reset steps-- as it's written above there's some room for misinterpretation. I've been trying to to get my '09 XB12Ss to run smoothly and thus far my TPS-reset attempts have been completely ineffective.

Specifically:
-How many times does one perform the throttle-on/throttle-off cycle, 3 or 4 times total?
-Does the the Throttle-on/throttle-off cycle also include the key-on/run switch-on step each time, or just the first time?

Thanks!

Thanks for the video, Steven.
I should have been more specific, I'm interested in clarification on the non-ECMSpy TPS-reset for the '08+ models.

-Eric.

[Stevenc150]

Sorry bro:

- 3 Times Total

- The steps are in order, the key off/on is the last step after the 3 throttle open/close moves.

[fakameanrepresent]

So instead of repeat the throttle open close 3 times, i only repeat 2 times?

[oh9bolt]

YOU DO IT 3 TIMES

[fakameanrepresent]

not trolling, thanks. so total of 3 times and not 4 times, :p

Hey fellas, resurrecting this thread rather than making a new one.

From reading through this, I think I might have a tps issue as well. So how do I go about resetting this on an '06 xb12? I guess where my confusion really comes in is that I did reset the TPS through ECMSpy and that's when it started running worse.

No engine codes. Opened airbox/K&N Filter, stock exhaust, breather reroute. That's it. Not sure on the map. I have no idea what the previous owner did and I'm only getting "incompatible ecu" errors when trying to reflash to a stock map (not sure if I have bad/corrupted maps or if my ecu is acting funny).

Any help, or at least a point in the right direction, would be great :)

[MotoPhreke]

Hey Liquid.. What do mean by worse? Is the engine surging? If so bring your idle back down a hair, I had to do that when I reset mine. Which is an 06 xb12r.

I'm not sure what could be causing the incompatible ECU error however..

[liquid51]

It was idling fine before I reset the tps. It was smooth from idle all the way to 6k. The only thing it was doing was sputtering ever so slightly when cruising in 5th around 70-80mph. After the reset though, it wants to stall on take off and it's generally just not as smooth as it had been (although I think it might actually be a little better at the top end).

Regarding the ecu, I'm hoping I just have some bad files. Know where I can find some reliable maps/eeproms?

[MotoPhreke]

Ok.. My experience with the ECM is limited.. I've only really done the basics, TPS reset and Flashing the Race Maps. I had run into the surging problem with mine so I wondered if you had as well..
Another member had created a site with a bunch of maps and manuals for the various years/models (buellmods.com) but I just looked and it seems to be gone now. I do have the stock and race maps for the 06XB12R but I'm not sure if they are the same for the S and wouldn't want to cause you any more issues than what your dealing with.
I'd be more than happy to share what I have, but lets see if anyone else knows if they are the same or not..

Anyone?

[liquid51]

Thanks Moto, I appreciate it!

I've also read a lot about the engine temp sensor being a source of a lot of strange problems. I'm going to check resistance on that too. I'm also betting my tps is off as well. I'll double check tps values when I get home tonight.

I'll give Randy a call too, I'm sure he'll know where I can find some stock '06 xb12ss maps ;)

[liquid51]

Well, TPS was off for sure. I feel like an idiot, attempting to reset it a couple nights ago without really reading up on how to do it. "Oh look, a TPS reset button. Why yes, thank you!"

Anyway, TPS was set to zero (whadda ya know :P ). Just had to fiddle with the TPS adjustment screw and bring it up to about 5.1 and she was golden.

I'm assuming that my engine temp sensor is still going to have to be replaced, but still, she's running better now than when I first rode her :D
