Comments on E-Tuner 4 for Android

★★★★★ Shawn Michael · Feb 25, 2019

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.

★★★★★ chris pinhiero · May 13, 2020

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.

★★☆☆☆ eric Lee · Jul 24, 2022

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.

★☆☆☆☆ James Mcbride · Jul 17, 2024

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

★☆☆☆☆ D C · Jun 26, 2023

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!

★★☆☆☆ DYNO Mark · Apr 26, 2025

Very basic, and lacking in Incremental adjustability.
