E-Tuner 4 app for iPhone and iPad

E-Tuner 4 is Edelbrocks latest exclusive iOS app for the Pro-Flo 4 EFI System.

E-Tuner 4 communicates with your PF4 ECU via Bluetooth, so you can manage and live-tune a variety of ECU settings such as air-fuel ratios, ignition timing, idle speed, acceleration fuel, or cold start mixture as well as monitor engine and sensor data in real-time wirelessly from your Apple device.

The E Tuner 4 Setup Wizard simplifies your Pro Flo 4 EFI setup by assisting you with selecting the proper base calibration for your specific application. All you need to know is the engine displacement (CID) and camshaft, and kit specifications, and youre good to go!

E-Tuner 4 applies a solid base calibration so you can run the vehicle without having to change any tuning settings. But, if youd like to make changes, E-Tuner 4 offers a selection of "Advanced Tuning" functions to help dial in your calibration and get the vehicle’s performance exactly where you want it. Whether youd like to run a bit leaner while cruising for improved mileage, or advance timing for more performance, the Advanced Tuning section is there for you. A diagnostic page for troubleshooting purposes is also available.

Once youre up and running, feel free to explore E-Tuner 4’s vivid gauge displays to monitor your engines performance. Unlike other tuning hand-held combos, you can actually use your iPhone or iPad as a mini-dashboard once youre done tuning.

You can also preview E-Tuner 4 without being connected to an Edelbrock EFI System by enabling "Demo Mode." This will allow you to access the apps main features, and interact with pages like the Setup Wizard, Advanced Tuning, and Gauge Displays to get a feel for how E-Tuner 4 functions.
