Chip Replacement
I am about to replace my ECM on a 1992 because of a no start situation (code 41), which corrects itself when I cool the ECM. Some have suggested that it may be the MemCal (chip) and not the ECM. Any thoughts as to whether I should replace the chip as long as I am replacing the ECM? Do I need to do any programming, etc to the new chip or can I just buy it from Chevy parts and put it right in? How expensive is the chip?

From a dealer a prom is probably around $75 to $100. Just a guess its been a long time since I purchased or sold a chip from a dealer.

Replacing the chip in the ECM is quite easy. I did it in less than an hour without instruction.
I would replace ECM with the original chip first. No need to spend an extra 100 bucks on a chip if ECM was the reason for your problems.
If you think chip is problem ,have someone program it with the mods you did on your car.
