    No fuel pump after TuneECU fail!

    Hello all,
    I recently did some work on my T509 (throttle body gasket, plugs, throttle body sync). I ran the bike with the airbox off which generated a fault code, which I expected. So after I put it all back together I hooked it up to TuneECU to clear the codes and reset the adaptations. The old throttle body gasket was leaking so I figured I'd clear the adaptations and let it do a "12 minute tune up". The bike fired up fine and ran well, although the idle was a bit high (1400rpm). So I shut it off to connect the TuneECU cable.
    Unfortunately, in the middle of the laptop reading the ECU on the bike, the battery on my bike died, even with a charger hooked up to it. Evidently a modern "smart charger" doesn't automatically compensate for a vehicle being turned on. Well, I was done for the night since it was late, so I disconnected the cable and put the bike on the charger and figured I'd get a fresh start in the morning.
    Well, today the bike cranks over great, but doesn't fire. No fuel pump sound, no idle air motor sound, but I can hear the main power relay click. TuneECU can't connect to the ECU after many many tries. I updated drivers for the cable. I checked on my laptop that it is actually recognizing the cable (and it is). I've used TuneECU for years along with this cable on this bike with no problems.
    I've verified that the battery is fully charged and healthy (although it is a Shorai Lithium Ion battery), and I have it on a charger. I've checked the clutch, sidestand and neutral switches. No voltage at the fuel pump connection. Checked the voltage at the fuel pump relay: 12v at the relay coil connections, and 12v at the Green/Red wire. The Black/Purple wire does not go 'low' when the ignition/kill is switch on; it stays at 12v. The main relay is switching on and there is 12v on the Brown/Pink wire coming off the main relay.
    So it appears the ECU isn't sending a fuel pump signal. Is it possible that the interruption of the TuneECU connection effectively killed the ECU on the bike? I'd hate for that to be the case as I've owned this bike since new. I'd appreciate any help or insight you guys could give me on this.

    Thanks, Oftaan

    You've corrupted your map. You need to "recover from a failed download." Everyone has done it.

    First, pull the fuse for your headlights and start with a fully charged battery. It was probably the headlights being on that caused your battery to go dead even on a charger. Also, those "smart" chargers for LiPo batteries probably aren't sufficient to keep the bike charged during a download. They're more of a trickle charger. Look into a more common 5 amp charger if you still have problems.

    Second, connect your bike to TuneECU. Under the "ECU" menu, go to "Recovery." That should do it. Then you'll have to reinstall the correct map for your configuration.

    Thank you. I'll go out and take the battery out of the other bike and parallel it and try again. I noticed today that the battery isn't charging up like it has in the past. It got to 55% and stopped, and that may indicate the problem. I assumed because I checked my battery voltage at 13.7v that it was good, but we all know what happens when you 'assume'. Still, 8 years out of a bike battery isn't too bad.

    So, shes up and running again! But it was not so simple. Even with a new battery and a second fully charged battery in parallel and a charger; it wasn't connecting. I tried a second latop, and for giggles I even tried an OBDII cable I have here for working on cars (it worked on an Audi and a VW, so I figured 'wtf'). I triple checked the drivers for the cable, which for the record is the "Crescent Trading" cable many of us have gotten from Amazon. I tried different connection sequences. The profanity flew.
    I wound up just doing a random Google search for "Tune ECU no longer connects". I found this on the Benelli forum:

    "I had a very similar problem with my bike turning over but not starting and also TuneECU stopped connecting to the bike, it turns out that the map loaded in the ECU had dropped so in theory I had no map, which made the bike not start.
    This is how I solved it, it may help you connect (taken from TuneECU thread).......

    If you ever get the programme drop out and then keep giving you the 'ECU not responding' message do this....

    1) Start the TuneECU programme on the laptop but DO NOT connect the cable or turn the bike on.
    2) On the ECU drop down menu hit 'disconnect', now on the Options drop down menu turn off the 'Auto-connect' option.
    3) Connect the cable to the lap top and bike.
    4) Turn on the bike.
    5) Go to the 'Map Edit' Screen on the programme and then go to 'file', 'open map file' and then open the map you require.
    5) Now on the ECU drop down menu hit 'Connect'.
    The bike will now go off and try to connect to the ECU, however what will happen now is because you have a map trying to load to the ECU you will get the message 'ECU is connected but not responding - Do you want to recover the ECU?', hit OK.
    The programme will now recover the ECU and when complete, re-load the map back into the bike again, just to ensure all is ok.
    That should be it."

    Of course it didn't work the first time. Or the second...or third. But I decided to try an earlier version of TuneECU (2.3.3) And magically, it worked. I loaded the map and let it finish. I disconnected and turned the bike back on. The fuel pump giggled to life with it's familiar "woo-woo-woo" (it's done that for probably a decade)! Pulled the trigger and bam, fired right up! This time joyous profanity of gratitude.
    Sorry for the lengthy explanation of things. I used to work as a Windows Systems Administrator, and I'm familiar with the reply of "It shouldn't do that, but it did/does". So file it under that. Maybe it was Mercury leaving it's retrograde. Maybe it was my lucky underpants. I don't know, I'm just happy it's running again. Maybe this account will help future civilizations.

    Did you try turning it off and then on again?

    Would you consider selling you lucky underpants? Worn, of course.

    Crash:
    Yes. Many times. I've used TuneECU on this bike many times before. Same laptop, cable and bike. The only thing that's changed is Windows 10 (and the battery failure). After I got everything up and running, I tried connecting with TuneECU version 2.5.8 and it didn't want to connect. But for some reason, version 2.3.3 continues to work. I don't know, maybe I need to remove and reinstall 2.5.8. Or maybe I should just leave well enough alone. Lol.
    I'd like to eventually either find a good tune for my bike, or find a local tuner with a dyno that can adjust the mapping for me. '97 T509, Black Widow underseat pipe, K&N filter, +2 rear sprocket.


    2Doggs: If I sell them, will my S3 stop running?

    Hahaha!

    Since I don't run Windows computers, I always ran TuneECU on a virtual machine running Windows 7. I've used Windows 10 at work, but I don't care for it. (For that matter I don't like Windows 7, but it's the best Windows version I've used.) I haven't updated TuneECU in years.

    That said, I no longer own a motorcycle so my information gets worse every year. If I buy another motorcycle it will most likely be carbureted and old.

    I know it's crazy, but I'm thinking about something like this:

    This thing is so densely packed with fun, it should be on the periodic table of elements. If I could ride it to work every day and park it next to my desk, I would.
