Default ECU replacement

Anyone replace their ECU? Or able to find instructions to replace at home?

Seems like an easy enough swap, but I don't know what all needs to be reprogramed.

I found a J2534 tool for $45 and would pay for 1 month of TIS for $95. I found the ECU reset by jumping pin 4 and 13 on the OBD connector. But I am not sure what all else there is.
