What if pin number 11 was damaged? Is there any problem on our motorcycle?
Pin 11 is + positive = this wire is is directly connected to battery. it keeps the ecu having standby power when the ignition key is off.
as long as your bike is running, should be fine. otherwise just buy a racing ecu.

How important does the standby power on our ecu? Thanks
