Reply To: GT250 EFI DSpec Stalls at Idle after Warm Up
Those connectors are quite similar to the ones I have which seem to me of good quality. When I refer to cheap connectors I mean this type:
These are ok in areas that don’t see high humidity or moisture but are totally unsuitable on a car; even more on a bike.
I would not recommend conductive paint.
If you are certain that moving the ECU about alters the idling I would try to push/pull each individual wire of the connectors to see if the behavior is replicated. I know this is easier said than done on a bike due to lack of space.
Also liberal use of contact cleaner is suggested but you probably have already tried that.
Incidentally are you sure that your GV250 EFI (2011) is a DSpec version? The electrical diagram in the Dspec manual I have, corresponds exactly to a Delphi ECU (MC05)
