*E-Tuner 4 App: A key component to the Pro-Flo 4 EFI System is the E-Tuner 4 app. This app features dyno developed base calibration which makes each system ready-to-run right out of the box. The E-Tuner 4 app uses a Bluetooth wireless connection to communicate with the ECU's self-learning capability to continually adjust the calibration to get maximum performance and multiple dash-displays that monitor engine vitals. The E-Tuner 4 app is free and can be downloaded from the Google Play Store, allowing the use of most personal Android-based smartphones or tablets.
