The 2007 Hyundai Tucson ECU can be found under the passenger side of the dash beneath the airbags that are on the top. This ECU is the main computer that all of the other modules give information to in Your car. If You are having problems with Your Tucson You should connect an OBD II scan tool to the port in Your car. This will allow You to read the ECU and see if there are any codes that have been thrown. Usually a vehicle runs rough when there are problems with sensors or other control modules. Most likely Your ECU is fine and should not need to be replaced.
