Does anyone know if it's possible to use a 05-06 revup ecu with non revup 03-04 engine? I've heard conflicting information about it working. Some people were recommending leaving the additional cam sensors unplugged and disabling nats (not sure why nats would need disabled if key is already programmed to the ecu). Any thoughts?

 

From what I understand it's not a good idea to do this. That is why when you see people blow up their rev ups, they end up purchasing an 03-04 ecu with the 03-04 motor.
