    I've had similar issues. You need to be sure to set the TPS with the engine hot (four bars by the old metric): a hot TPS will read about .5v higher than a cold one, and if you get too far outside of the spec 0% throttle numbers the engine starts idling really high (which made my urban commute pretty interesting for a couple of weeks before I figured out what I'd done wrong).

    From your description is sounds like you are trying different settings without taking into account the temp of the sensor.

    Hey Guys.

    I thought I had solved the issue. I got the bike back, let it sit in my garage for a complete night and the next morning connected TuneECU. The image attached portrays the readings. Saturday I went out for a ride after getting the mentioned reading, the bike was impressive, the power was surprising compared to before, and its performance flawless. I took the bike for a 200KM ride with changes in altitude and terrain, not a single glitch. I did notice the fuel consumption went UP, 180KM till the light came up. Before it was like 240. Anyway, the story continues... read next post.

    After the 200km, as soon as I got to the garage, with the bike still flaming hot I took the following reading:

    Notice how the TPS Voltage changes from cold to hot, in this case it went down. Thinking the problem was fixed, the next day I went for a more demanding ride, more curves and changes in altitude. After about an hour or so, the bike started to misbehave, it started to raise its rpm, and pressing the clutch did not work. I would have to pull over, put the bike in neutral, turn it off, wait, and then turn it back on again. But the problem persisted and got worse and worse as km were eaten up. It got to a point in which the bike reved and then lowered as if I were opening and closing the throttle abruptly. Suddenly the FI light came on. As soon as I got home, with the bike hot, I did another reading with TUNE ECU. Here it is:


    Guys. I need your help.... I don't know what to do now....

    Maybe you have a TPS that isn't working correct anymore.
    I should try another TPS adjustment(also check wiring from the TPS to the ecu, and for bad or polluted contacts), if the same fault returns you know that you have a bad TPS.





    The first 2 pictures with the TPS cold(1%) and warm (0%) is the same with my bike

    Yesterday I had an epiphany, it seems that every time I connect the bike while the engine is off the readings are right, it is after the bike is warm that it portrays the issues, I also noted that the voltage of the battery after a long ride is still 12 volts, it does not increase. So i thought, ok so what if the TPS (hardware) is fine, what would be a factor that would send the wrong signal to the bike? Current! if the current is not regulated adequately the TPS will not receive the right amount and hence it will transmit a wrong signal. So i went ahead and checked the regulator output. With the bike on, as I accelerate the output of the regulator decreases! Is this right? So again, I thought of the last sympton, as I was riding at 100km/h the bike started to accelerate an decelerate by itself and then the FI light turned on. I read the code and it said it is code p0122 which says that the TPS Voltage is low. I took down the regulator today and I am going to take it to be tested. I will have u posted with the outcome.

    All you have to do is turn the ignition off will TuneECU hooked up to the motorcycle and then adjust your cables at that point. With TuneECU hooked up it will keep the stepper motor retracted. This is directly from the Description pdf

    And make sure you have the most current version of TuneECU.

    I have the latest version of TuneECU but I'm not able to select the test. It's colored grey and the wanes that I can select are black. I tried double clicking, also doesn't work.
    Just turning off the ignition with TuneECU connected doesn't retract the stepper motor!

    That is true! That's why there is a test button for that feature.

    If you can't select any of the tests - are you able to connect and see the ECU data in the Map Edit or Diagnostics pages?

    I can select some tests, like the steppermotor and 2de throttle test. I can load maps and use the diagnostics page but I can't select the adjust cable test witch is colored gray. The ones I can select are colored black.

    Are you running the latest version?? 1.9?

    When you double click on the adjust cable test it will tell you at the very bottom to turn off the ignition and adjust but to not exit out of the software.

    I don't know why yours would not be selectable.

    i have the same problem, I cant choose this test, everything else works fine.
    Any solution for this.
    Maybe it has to do with only 2006 models?

    Thread revival time...

    Removed the canister and the SAS and disabled both using TunceECU (v. 2.5.3) on my 2011 990 Adventure Dakar Edition. I then installed the Rottweiler filter and loaded the 2-into-1 map from the TuneECU website. Did the 15 reset adaptation and I'm still getting the FI light blinking. I noticed that the TPS was at 0.72.

    Following the directions on this thread, I adjusted the throttle position sensor twice: first so that it reads 0.65v, and a second time to read 0.58 v. in both cases, the following error message shows up in TunceECU and the FI light blinks (a cycle of 7 blinks, then a pause):

    P0223 2nd throttle position sensor, high voltage or short circuit to battery

    I also did a 15 min Reset Adaption after the first adjustment.

    The 2nd Throttle test on the Test tab in TuneECU passes and returns the error message is replaced with "No errors". However, the FI light still blinks, and after I re-cycle the switch, the P0223 error returns.

    Is the "2nd TPS" the same as "TPS" ? Is this a reference to the TPS on the rear cylinder? Does it need to be adjusted separately from the front TPS?

    Seems like a bad TPS, since you disassembled the TB's for the new airfilter setup, go back and redo your steps, maybe some connector got loose.

    When you twist the throttle, does is go smoothly in the voltage up to 96% and 3,8v (+/-)?
