How do I identify a stock versus modified computer chip?

The reason I am asking is because ever since I purchased my ZR1 the cooling fans come on right away after starting up the car. No codes present, and there is no obvious wiring between the cooling fan relays that I can see to make them run all the time.

So this morning I pulled the chip and wrote down the numbers off it. So far it appears to be stock.

This cooling fan running all the time was ok during the summer but with the fall/winter/spring its annoying and not necessary.

My thinking is that the chip is modified and will turn the fans on all the time. Is it possible to modify a stock computer chip if it turns out to be the oem chip?

Thanks in advance.
