I keep getting an error when trying to write a tune to my 2007 cobalt ss/sc, it will say "Controller Unlocker: Timeout" or it will get to about 63.5% and say "Writer Timeout" I can't start my car I've tried unplugging battery, I have the battery hooked up to a charger, the Radio fuses are out I've tried 2 laptops, all the ports and 2 cords. I would really appreciate anyone who can help.
