idk i put one on my old car Volvo s70 T5, i put an upgraded ECU i figured they had them for cobalt

there is no aftermarket ECU unless you change the aspiration of your car and get it through zzp or another well known company who does custom tuning on ecu's they have in stock. if you're planning on going fully bolted and then tuned, i would suggest you find an HP tuner around your area to tune your car. otherwise, talk to vince at trifecta performance and he will give you a box tune
