When using BBL on a 08 Z06 E38 I consistently get TCS/AH issues. It looks like it happens when the V2 handshakes with the PCM. Car continues to drive fine but TCS/AH lights are lit up and TCS/AH is fully disabled.

I do also randomly get this same issue even when not using BBL (e.g., when using my laptop to scan and tune). It seems more prominent when using BBL though.

I had the same problem on my 08 Z06 found the problem was that I connected to the ALDL after the engine was running. Plug into the ALDL before you start the engine and it should be OK.

Good tip, thanks. That may solve the BBL issue. Now I just need to figure out what's going on that trips TCS/AH when not using BBL...
