The BCU and TCU are NOT VIN coded. I discovered that when I was having an issue with wing and top.
When I went to put top up it wouldn’t allow me because it was looking for a signal from wing. I had to turn off the car and restart it to get the top to go up.

I had removed the speed deployed spoiler and went with fixed wing.

so I installed the BCU from SRT roadster and my problem went away. No coding needed.

before you spend a crap ton of time, just swap it and see

you never know and your commitment is 10-15 minutes
