Keep in mind that BCMs from SRT6s were never intended to operate the wing. There is some chance that a non-working wing when using a replacement BCM is because the replacement BCM came from an SRT6. I have no clue what the differences in software in the BCM (or even hardware) might exist between N/A and SRTs. I know one thing, the Germans did NOTHING the simple way with these cars.

Im interested in hearing what you find with your swapping and trading BCMs. Again, Iv'e been here since 2009. Only in the last year or two have we had BCMs dying. We are in unknown territory here, but with enough people experimenting and posting their results, we will learn........
