## E-Tuner 4 Description
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

## E-Tuner 4 Reviews in United States

### ***-- "Needs work"
Adequate at best. No data log capabilities. Hard to figure out a problem when you have one. The Android counterpart does have data logging. They need to update this app and also have a way to export the data.
-- Smitty0110, 2024-09-03

### ***-- "Hard to read under real world conditions"
It is good that there is now a version for IOS. It would be great if there were some configuration options for the gauge display. There is inadequate contrast between the red and black to read to be able to read well in full daylight.
-- ......what happened??????, 2024-05-04

### ****- "Almost as good as the android version"
It does everything that the android version does, except keep your device from turning the screen off. 

The telemetry is great too have, but it’s not very useful if you can’t see it. Can’t find an option in the phone’s settings or in the app to keep the screen on. 

What I would still like from the app is for it to rotate with the phone (vertical instead of horizontal) and to be able to have at least one page of gauges that I can configure (digital v. analog, position/size, what sensor is being displayed).
-- Squiggz77, 2021-12-02

### ***** "Needs a little tweak"
Edit 10/8/2021 the temperature issue is fixed. To the people having trouble pairing this to your iPhone or iPad, you must first update the firmware using a non-iOS phone or tablet. The pro flo ecu will not work with your iPhone without this update and you can only update it with an android tablet or phone. After the update it will see and pair with your iOS device just fine. 

Old review: The current version (as of 8/12/21) displays the coolant temperature incorrectly. Hopefully this will be corrected in an update soon.
-- Thunder weiner, 2021-10-08

### *---- "Buddydog101"
E tuner4 ecu search cannot find my iPhone 8 or iPad 6th gen will connect with asus tablet that came with profile 4. Was about to purchase a Samsung tablet when I found they written a iOS app.
-- MTyb, 2021-09-12

### ***** "Finally here for ios"
Love the app! I don’t have to keep my tablet with me anymore. Once they fix the temperature issue with the app it will be perfect!
-- aguitarhero, 2021-09-10

### ***** "EFI"
Love the ability to tune on the fly.
-- Shepp99, 2021-08-06
