How to Supertune a Chevy for Horsepower
- 1). Open the vehicle's hood and disconnect the negative battery cable.
- 2). Locate the vehicle's electronic control module. As the location of the module varies depending on the vehicle, use the chart provided in the resources section below to find the specific location.
- 3). Remove the mounting screws from the electronic control module and remove its mounting location.
- 4). Unscrew the access cover from the electronic control module using the screwdriver.
