One of my other concerns is emissions. When you swap to a different car ECM, I'm wondering what kinda of problems that will create when one goes for their annual emissions testing? Doesn't the computer store the VIN info, and I wonder if it will throw a red flag when the emissions testing machine is hooked up to your car, and the VIN #s don't jive?
