### 5/5 — Won’t sync

*2026-05-15*

All of sudden won’t sync with new iPad or iPhone but still syncs with 10 year old iPad

### 5/5 — Just works

*2026-05-09, version 8.2.0*

Great bit of kit. It was very easy to fit and set up. The instructions were a bit vague regarding the static timing point and its relation to the app readings but with my timing light, I was able to work it out and adjust the reading on the app to match the actual firing point. The app is great. I love the dash layout as it matches the gauges on my car. Very happy. I wish I had bought this years ago instead of wasting money and time in substandard electronic conversions.

### 1/5 — App needs some work

*2026-01-26, version 7.0.1*

The Tune+ is a great device but the App needs improving. If you run the car on a rolling road you can nake adjustments but bizarrely it doesn’t save the settings. You have to write them down. Ideally you should be able to change settings while the car is running and simply click Save Curve. Hopefully this will be added soon. Then it will be an amazing device.

### 5/5 — Excellent piece of kit

*2025-12-31, version 7.0.1*

Would thoroughly recommend. Car starts easier and creates less exhaust fumes. Very pleased

### 2/5 — Quite a few critical flaws

*2025-08-13*

Whilst the app has some useful features I noticed that you can’t check for or install firmware updates. The button is without function. MAP function automatically activates 1500‘ threshold, even after deselection. The selection triggers a 10° ignition advance in addition to whatever value is set. The software will freeze when trying to store a new profile after a restart. This requires you to deactivate and activate the device in the app before being able to store the profile.

### 2/5 — App needs some work

*2024-02-23, version 5.0.4*

The Tune+ is a great device but the App needs improving. If you run the car on a rolling road you can nake adjustments but bizarrely it doesn’t save the settings. You have to write them down. Ideally you should be able to change settings while the car is running and simply click Save Curve. Hopefully this will be added soon. Then it will be an amazing device.

### 5/5 — Terrific Tool

*2023-11-29*

This app makes it easy to develop and save ignition curves. The virtual gauges also help you measure the accuracy of your tach and speedometer.  Block temperature is useful, as is ammeter and volt meter. 

Switches easily between vehicles and allows unique access codes.

### 1/5 — Not working right.

*2023-07-01*

Won’t stay connected and show dashboard

### 5/5 — New features

*2023-04-24*

The new tune feature that allows timing changes while the engine is running works great. Can tune the engine in half the time now.

### 5/5 — Easy install

*2023-04-18*

A thing of beauty!
