Horrible

This is the worst punishment I think I’ve ever put myself through and probably the most expensive this fuel system is a absolute disaster and vey inconsistent

Works well

App works well and connects easily.
My only real complaint is that it only works in landscape mode.
It would be awesome if it would also work in portrait/vertical mode on the phone.
It is quite cumbersome to switch between music or map app and tuner app while driving.

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.
