Update

Please update this app for the love of Pete

It’s OK

The Android version is way better than the iPhone.
iPhone 17.

No recent updates & customer service

You haven’t updated this app for 2 years? Do you not have a product management team constantly trying to innovate your products? All your YouTube videos are old. What’s your marketing team doing???? You need to invest in marketing and updates. Get out there and compete with Holley. Also get more friendly customer service for EFI. One guy is friendly…I don’t want to put his name here. The rest are dismissive and have zero customer Service skills and I’ve left every call feeling frustrated. Like when asking what fuel pressure regulator they recommend for this system….the response was “there’s some on our website just go look.” Holley however gave me all their exact part numbers, what the differences were, and what they recommended. I ultimately chose Edelbrock for the port injection, so I’m going to roll
The dice and hope The tech is solid and that I don’t need much customer Service. I hope
Someone in leadership at Edelbrock hears this feedback.

Very good

Very good and easy.
One recommendation is to add a GPS speedometer to the gauge channels, then it’d be perfect.

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.

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.

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).

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.

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.

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!
