    Thanks for the help Gustavo. Unfortunately I don't know anyone nearby with a 990. When I do the test I do hear something - sounds like a solenoid or something. Is this what the cycling sounds like?

    Also, how do I distinguish a problem with the pump itself from a problem with clogged filters? I assume that clogged filters result in a gradual loss of pressure and hence a gradual loss of performance. What happens when the pump itself dies? Does it die all at once, or does it gradually lose pressure? I'd rather not replace the pump if it isn't necessary.

    When you flip the key on, engine switch on, you hear the FI cycling, correct? Most of that sound comes down from left tank, then there is a more metalic sound from the throttle bodies secondary butterflies.

    Testing the pump does a very similar noise.

    About problem with the pump and fuel filters, can't help here. The filters should be serviced once in a while, there is extensive material in ADVRider about them and their lookalikes.

    You can order a service kit, and see if it solves the problem.

    About pump failure, dunno if it goes off suddendly or might loose pressure.

    What do you feel wrong with your bike?

    It was running fine, then it stalled at a stoplight. It had a hard time starting back up and would only run for thirty seconds or so. That was yesterday - today it won't start at all. No error codes, no recent work on the bike, nothing obvious. I would have thought the fuel filters are clogged, but I would expect that to come on more slowly and to initially just cause a loss of power in the midrange as others have reported. That never happened for me - everything went from fine to not starting at all in five minutes.

    And DAMN those fuel pumps are expensive!

    Anything else it could be? I'm all ears...

    got fuel, or the right fuel!? :huh

    Don't want to misslead you, i've never had a problem with 990 Fuel pump, only the usual 950 FP of previous bike, but from your description *could* be a bad pump.

    Maybe someone else might add some insights?

    If you checked the fuel pump and found this is to blame, I have chinese replacement I am selling.

    I adjusted the throtle cables, bike then had a hesitation at about the 4K rpm mark - but was rideable.

    I then hooked up Tune ECU to the bike -
    Selected 'adjust throttle cables' it then instructs you to turn the ignition off (I did at the key).

    I adjusted throtle cable (pull only).

    In the interim Tune ECU reported that the connection had been lost.
    I restored the connection.

    What should I do now?? Tune ECU does not seem to recognise that I'm back from throtle cable adjustment for it to finish what ever it needs to do.

    The bike runs worse than ever - it now stalls from idle...
    Any ideas??

    >>>Adjust the cables as above, get an electronic balance tool and adjust the throttle body balance, reset adaptation and 15 min idle. <<<

    For those just starting to use Tune ECU, here's a quick video on where the connectors are, how to connect and download a map, etc. It's not a software how to, but done just to help people see how easy it is to connect to the bike, and download a map. Let the dissention begin.....

    This is something that has escaped me all the while. I have been using TuneECU for the last few months, done quote a few of the tests but never been able to d othe "reset adaption" after a map download to the ECU. This option stays disabled - light gray color on my TuneECU all the time. mine's an '07 EU bike - does it have anything to do with this ?

    That probably has to do with the map you're loading in. Some earlier maps do not allow all tests to be performed. Try a 07/08 AK map see if these tests become alive.

    Worked for me.

    Thanks Zuber - what's the 'reset adaption'?

    My filter blocked on way to a ferry, bike would only run for couple of mins then die, speed limited and power dies with throttle open. It then collapsed and filled the injectors with crap. Source of problem: previous owners bad hygene!

    KTM say change filters every 10000km or something so if you haven't then its a good starting point. Easy to check if you take it out and have a look.

    Don't want to sound unhelpful but its posting a bit off topic though, not much to do with ecu tunes? Is anyone moderating this thread could keep these posts in the right places? Happy to help but they should realy be elsewhere I think.

    Not unhelpful at all, the question arised in how to test the FP with TuneEcu... kinda borderline, and then evolved to the Fuel Pump itself.

    But you're right.

    Ok guys, I'm very new to this TuneECU thing. Just downloaded the program and it looks great, but I don't have the experience to start changing things in the mappings, and I don't want to read through all the pages in this topic, so here's my question:
    Did anyone manage to find the holy grail (aka, a mapping for a 990 with akra's/wings that gets rid of the hesitation at around 4000 rpm but doesn't burn as much fuel as the factory akra map)? Please do tell!
