how does that work is it flashed? i just noticed it when i pulled the entire engine harness out the car since it got totaled and notice it has a s10 computer in there.

The 1227165 ecm was used in a multitude of applications. The memcal and eprom programing determines the application use. It is a uv erasable eprom not flashed based.
