What would cause these two BCM codes?
The new rig has thrown these two codes a few times now, just wondering what would cause them and where to start looking. Car is a 2001 Z06 Lingenfelter twin turbo. Also has a 4L80e swap ect....

With your title ".....two BCM codes.." and no indication of a sensor under which those code occurred, one would think they were under the BCM.
However it's impossible f'or the BCM to produce a "U1064 Loss of communications to the BCM" so it's anyone's guess what they really relate to.
I'll take a guess to start off you list of guesses. The codes appeared under "B0 - RFA " sensor. If so that's pretty normal codes for the RFA.

I was under the impression that they were already turned off in the tune, but if it keeps throwing the code maybe not. Where about is the RFA located in the car so I can check the wiring to it.
