E-Tuner 4+

E-Tuner 4 Plus Edelbrock's latest exclusive iOS app for the Pro-Flo 4 Plus EFI System.

E-Tuner 4 Plus communicates with your PF4 Plus 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 Plus Setup Wizard simplifies your Pro Flo 4 Plus 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 you're good to go!

E-Tuner 4 Plus applies a solid base calibration so you can run the vehicle without having to change any tuning settings. But, if you'd like to make changes, E-Tuner 4 Plus 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 you'd 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 you're up and running, feel free to explore the E-Tuner 4 Plus gauge displays to monitor your engine's performance. Unlike other tuning hand-held combos, you can actually use your phone or tablet as a mini-dashboard once you're done tuning.

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

*** Warning! ***
E-Tuner 4 Plus is only compatible with the Edelbrock Pro-Flo 4 Plus EFI System. It is NOT compatible with the standard Pro Flo 4, Pro Flo 3, E Street V1 or V2 EFI systems nor does it work with other Edelbrock Legacy EFI Systems.

The E-Tuner 4 Plus app supports all iPhones and iPads running iOS 13 and higher at this time. Please check back later for updates
