Description
E-Tuner 4 is Edelbrock's latest exclusive Android 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 Android device.
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. If you have one of the EFI systems mentioned above, please go to http://www.edelbrock.com/automotive/mc/efi/support.shtml and download the appropriate Android app files.
The E-Tuner 4 app supports most devices running Android 6.0 and higher at this time. It is recommended to use this app on 5 to 7 inch Android phones and tablets. Please check back later for updates

Great product and support. Has different gauge layouts to choose from. Easy to install, good directions. Support team is quick to answer questions and very knowledgeable. Nate is the man! Defrock seems to be improving the system such as can bus gauge(s) addition. For the person to give this app a 1 star because he demos'd the app and couldn't figure out his Android to enable rotation, you should stay far away from any automotive aftermarket product. If you actually bought the system that included the tablet, the app would rotate for you.

Set up wizard locks up and does not work. Had to manually install map. Have problems connecting sometimes. Car is running Awesome. App could use some work. Very happy with this system.

Great app, wish they would add an option to change the vacuum advance to manifold vacuum instead of port vacuum
★★★★★Jeff Hastings· May 3, 2019
Outstanding! However, setup hangup so loaded the tables manually and I think that may have been easier than using setup. The app is very easy to use and has access to most current documentation for reference. Using Bluetooth is great as I cut off a cable with my door on my Holley Sniper that I replaced with the Pro Flo 4. Very little tuning to do, ran great right out if the box and runs better every day. Very happy. Disregard the bozo who wrote the 1-star review. It's a landscape only app.

I have to wait for about 45 seconds for o2 sensor to warm up before starting. If I don't then there is no afm reading and my car run very poorly. I know this app is far from perfect and have been waiting for it to be updated. Go on over a year with no revisions to the pro Flo 4 software. Seems that you guys stopped developing fixes and upgrades to this product. Had msd atomic efi and that's basically what they did.

Can't connect way too often. Sometimes perimeters change on their own. I spent so much money to have to deal with a possible time bomb

Works okay. Needs data logging function & needs an easy way to enable recording of the screen when observing gauges or the diagnostic screen. Needs the ability to check settings without having to be connected to the ECU which means maintaining a copy of the database on the phone or tablet. 1 star because app forced me to turn on Location to pair with new phone. DEFROCK DOES NOT NEED TO KNOW MY LOCATION!

Very basic, and lacking in Incremental adjustability.
