So Blaze II's BCM pulls about a 2A. parasitic draw. I pulled the BCM from Blaze I, which eliminates the battery drain, but won't allow the vehicle to start.
If I also pull the ECM will it work?
Does the BCM also store the odometer setting? This car only has 119k vs 169k on Blaze I.
What is my most cost effective reprogramming option?

Vehicles are both 2001 Blazer LTs
