What are your guys thoughts on buying a second ECU? I have to send my ECU off to active to get my software installed. Being my only car it will be kind of difficult to deal without. I know you can rent a car but If I could buy a stock ECU and keep the car running, plus resell the stock ECU when I'm done.

My dad did it on his z3m when he got the car supercharged and said it worked like a champ. Just didn't know if thats possible with the z4m.
