I put my ECU on the back of the core support near the left headlight.

I have VA in my truck and it takes up most of the space behind the glovebox (as well as most of the glovebox itself - you get a plastic insert from VA that is about 3" deep to replace the original glovebox). You could probably get away with mounting a stock GM ECU on the firewall behind the radio.
