Using the PedalMonster is super easy. First, connect it to your vehicle's OBD - II port. It's a plug - and - play setup, so you don't need to be a mechanic. Once it's connected, you can start customizing your throttle response. You have three driving environments to choose from: City for your daily, smooth drives; Sport to add some extra oomph in the mid - range; and Track to get into power faster. With 150 unique throttle contours, you can fine - tune the 'dead spots' in your pedal. Just use the mobile app or iDash to control and view the activity in real - time. Now, for the safety part. The PedalMonster has a great safety system. It constantly checks the signals between APP1 and APP2. If it notices anything off, it'll return the throttle to the stock settings. This means you won't lose power while driving. As for maintenance, there's not much to do. It's designed to be reliable. But if you're going to use it with a Derringer tuner, make sure to choose the right option and get the adapter cable. And always refer to the installation process and owners manual for any detailed steps or troubleshooting.
