TuneECU are you listening?
Isn't ECU is still going to be looking for it? The purpose is so you can't bypass the ignition and hot wire the bike, you need the real key that has been previously programmed to the ECU. There should be a way to turn off this feature, maybe the Tune ECU will be able to at some point. This must be required in Europe because my Westfalia Sprinter has the same feature and it crapped out and was expensive and hard to get and no way to get around it.
If the ECU is losing communication with the ant. ring, we should be able to replace it with a spare one, the key is the same so it should still be recognized and be able to start the bike. I hope.
