NNBS Standalone Harnness & BCM ??
Hey just wondering if any of Gurus out there has any input on this?
I am going standalone harness with Holley Dominator EFI for twin turbo NNBS.
I know that guage's wont work which is okay but would love to keep the AC. The only problem that it is controlled by the BCM and I want to gut out the stock ECU and engine harness and worried that the BCM will freak out and stop working.
Any Input will be helpful ?

The only way to do it is with the pcm as a stand alone controller for the major vehicle subsystems. If you take it out completely you get to roll down the windows.
The interior HVAC will stay working correctly but it cannot control the compressor without the pcm. Your only option would be to put a toggle switch on the compressor with the compressor safeties wired in series with the ground signal to the added relay coil.
