E vs Part 117

E-Tuner 4 is Edelbrock's latest exclusive iOS app for the Pro-Flo 4 and EZ Street EFI Systems. E-Tuner 4 communicates with your PF4 or EZ Street 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 iPhone or iPad. The E Tuner 4 Setup Wizard simplifies your Pro Flo 4 or EZ Street 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 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 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 E-Tuner 4’s vivid 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 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 functions. *** Warning! *** E-Tuner 4 is only compatible with the Edelbrock Pro-Flo 4 and EZ Street EFI Systems. It is NOT compatible with V1 E-Street, V2 E-Street, or Pro-Flo 3 EFI systems nor does it work with other Edelbrock Legacy EFI Systems. The E-Tuner 4 app supports all iPhones and iPads running iOS 16 and higher at this time. Please check back later for updates
