M880 defueling after start
Posted: Fri May 25, 2012 12:53 amHi - we're having a problem with an M880 mounted on a Ducati 1098R with an SDL. I'm working with a pro tuner, and we've both gotten to the 
level with this problem.
We have the sync/ref mode set to 60 (Ducati special) and the bike starts fine. Right after starting, however, it slowly loses RPM, the lambda readings go lean, and the engine dies after about 5 seconds. It's very much like the fuel is slowly being shut off.
We tested the injectors using the output testing and they seem to work fine. We measured the injector output at 3, 6, 9, and 12 seconds and got proportionally correct fuel volume. We swapped fuel tanks (including pump and filter) off of a running bike, so we eliminated that. We've also swapped batteries and spark plugs and got the same result.
We turned off the lambda feedback and still the same result.
Does this sound familiar to anyone? My friend is sending the ECU to Motec in Calif to get tested, but I thought I'd send out a feeler to see if someone has seen this before.
Thanks!
