The 123\Tune+ app is designed for configuring and tuning the 123\Tune+ ignition systems for classic cars. The app is available for both iOS and Android devices and can be downloaded for free from the respective app stores.

Here is a brief explanation of how the 123Tune+ app works:

1.         Connect the 123\Tune+ ignition to your classic car's engine and make sure all wiring is connected correctly.

2.         Open the 123\Tune+ app on your mobile device and connect it to the 123ignition via Bluetooth.

3.         Once the connection is established, you can use the app to adjust and configure the 123ignition. For example, you can change the ignition timing, adjust the centrifugal/vacuum advance curve and use the anti-theft option.

4.         The app also provides graphical views of the ignition timing and other parameters for easy reading and comparison.

5.         After you set your desired settings, you can save them to the app and reload them later if you want to use them.

In short, the 123\Tune+ app is a handy tool for tuning your classic car. It offers an intuitive interface and plenty of features to improve and optimise the performance of your engine.

In the following guide, we will take a closer look at all the features of the 123\Tune+ app.

-

On the side of your 123\Tune+ is a blue LED, this LED indicates the status of your bluetooth connection, there are 3 possible situations:

The blue LED is on constantly:

If the blue LED is fully lit, it means that the 123\Tune+ is not having a connection to a device(smartphone or tablet). You can connect to your 123\Tune+ in the 123\Tune+ app at settings under the heading Devices by selecting the 123\Tune+.

The blue LED will flash:

If the blue LED on your 123\Tune+ is flashing, we recommend you reset your bluetooth connection. We have a special procedure for this:
Restart your phone and try to connect. If that doesn't work, the following steps may help you connect to the 123ignition:

1. Turn off all your phones/tablets which are close to the 123\Tune+ and have the 123\Tune app installed (very important).

2. Turn off the engine key. At this point, there is no power on the red and black wires.

3. Connect the black wire from the ignition to the red wire (+ from the coil).

4. Turn on the ignition key (red and black wires are now both powered by 12 volts).
The blue LED on the side of the 123\Tune+ will flash for about 10 seconds.

5. After the reset procedure is complete, the blue LED will be on constantly.

6. Turn off the ignition key and wire everything back to normal.

7. Now the PIN is 1234.

The blue LED is completely off:

This can mean 2 things or you have connection to the 123\Tune+ App, then everything works as it should. Or you are not getting a connection to your 123ignition, in the majority of cases the 123ignition is then not getting voltage. It is also possible in rare cases that the bluetooth module is faulty, in which case the blue LED will also not come on.

What is centrifugal advance (Centrifugal curve)?

Centrifugal advance (centrifugal curve) is a mechanism used to control the ignition timing of a petrol engine. The purpose of centrifugal advance is to optimise the ignition timing of the fuel-air mixture for efficient combustion.

Having the ignition timing earlier ensures better combustion of the fuel-air mixture because it gives time for efficient combustion. This results in better engine performance.

What is Vacuum Advance (MAP curve)?

Vacuum advance is another mechanism used to control the ignition timing of a petrol engine. It works together with centrifugal advance to optimise ignition timing for different engine speeds and loads. It uses the vacuum in the intake manifold, which is basically always present when the engine is running, but not (anymore) when the throttle is fully open.

The vacuum value is actually a measure of engine load. At partial load, the maximum amount of mixture does not enter the cylinder, to compensate, it is desirable to ignite the mixture earlier. (Vacuum advance) In racing and rally engines, vacuum advance is not used. Vacuum advance can help improve combustion / emission values and make the engine run more economically / smoothly at part-load.

Setting Curves

Are you looking for advance / vacuum curves for your car?
Unfortunately, we do not have the unique curve ready for every car/engine/model. But on our website (www.123ignition.com) we have many example curves for many types.
All our 123\Switch models have a curve table, from there you can make a good basic curve.

What the right advance curves are for your car depends on many factors. In many cases, you can find a lot of information in your car's old documentation about what curve your car have. You can also always consult your local 123dealer, they often have a lot of knowledge about specific brands and curves.

Dashboard

The images on the right show the Dashboard of the 123Tune+ app. While driving your classic car, several data will be displayed here. The dashboard shows the following parameters :

– Crankshaft advance
– Time
– Vacuum
– RPM
– GPS speed
– Battery voltage,
– Spark strength in Amps
– Temperature of the 123ignition.

On the bottom left you will see a red or green dot, when you have a green dot you receive connection to your 123ignition+, when and red dot there is no connection to your 123.
There is also a Tune button on this dashboard. This button can only be operated when the engine is running, more about this function can be found under the heading Tuning function.

Crankshaft advance

Indicates crankshaft advance. The crankshaft advance is a sum of the centrifugal advance, vacuum (MAP) advance and static advance.

Time

The local time on your device.

Vacuum pressure

Indicates the measured vacuum pressure. The scale (bar/kPa) can be changed at Settings.

RPM

The RPM gauge displays crankshaft RPM.

GPS speed

Your vehicle speed, based on your device's GPS.

Battery voltage

Indicates the battery voltage.

Coil current

The primary coil current is an indicator of the spark energy.

Tuning

The Tuning function is a quick and easy tool to add or subtract degrees advance, to find out which advance gives the best performance at a certain RPM.
More info

Temperature

Temperature of the 123ignition.

Curve tab

This tab is dedicated to the centrifugal and vacuum (MAP) curves. You can view and modify the active curve in the 123, create new curves, import and export curves.
More info

Rev limiter

The red bar indicates the soft rev limiter active range. When the RPM speed is above the rev limiter threshold, the 123 starts skipping sparks, trying to limit the RPM.
Here

Digital gauges

The digital gauge displays the gauge value in digital form. You can enable or disable the digital gauges at Settings->Show digital displays.
Here

Settings

At the Settings app, you can see all found nearby 123\Tune+ ignitions, immobilize the 123, change PIN and other general settings.

Connectie

If the LED is red, there is no connection to a mobile device. If the LED is green, a connection has been established with a mobile device.

Tuning Function

When you operate the Tuning slider the ‘-‘ and ‘+’ buttons light up, these buttons allow you to adjust the advance while the engine is running.
By pressing ‘+’ (advance) you can increase the total amount of advance by a maximum of 10 degrees, in increments of 1 degree
Pressing ‘-‘ (retard) allows you to reduce the total amount of advance by up to 10 degrees crank, in 1-degree increments.
This function will come in handy if you have your car on a roller bench(power bench), and you want to optimise engine power.
The found advance or delay is not stored in any way, so you will have to remember your findings, and adjust the active advance curve.
Pressing the cross will close the Tuning function.

Function switch

Allows you to turn the tuning function on and off.

Increase

Pressing '+' (Increase) allows you to increase the total amount of advance by a maximum of 10 degrees, in 1-degree increments.

Decrease

By pressing '-' ('Decrease'), you can reduce the total amount of advance by up to 10 degrees crank, in 1-degree increments.

Close

Pressing the cross button closes the Tuning function, but does not save any data.

Green strip

On the tachometer there is also a green strip, by adjusting the value under the meter you can adjust this green strip. A time measurement is started in the green strip, this time measurement is displayed below the meter in a digital field. With this function, you measure the time between 2 revs. A nice feature to test the performance of your engine.

At the bottom of the dashboard you can control several screens. We swipe to the left and move on to the next screen, Curves.

Curve settings

You will see an overview of your centrifugal curve and your vacuum MAP curve.

MAP stands for Manifolt Absolute Pressure.

The properties of the curves are shown in a graph and a table, so you get a good overview of the curve.
If you receive connection to your 123Tune+ ignition you can also adjust the advance ‘s curve, this only works when the engine is not running.
With a running engine you cannot save the curve in the 123ignition.

You can adjust the curve and by pressing Done you can also save the curve, but to send the adjusted curve to the 123ignition you will have to switch off the engine, but make sure your ignition is still on otherwise the 123ignition will be de-energised (provided your 123 is connected to the ignition) and by pressing the write button the curve will be written to the 123ignition.

Pressing the read button will read the current curves stored in the 123ignition.

Once you receive connection to your 123ignition you will see that the Edit Centrifugal curve and Edit MAP curve buttons will light up orange. By pressing these buttons you can adjust the value of the curve. Here you can enter and adjust your centrifugal advance ‘s curve and your vacuum MAP curve. It is also possible to delete or add a point in the curve.
Once you tap the Edit centrifugal curve or Edit MAP curve buttons, you will be taken to 1 of the screens below.

Files

This button allows you to load your own curve files from your device.

Save

This button allows you to save your custom curve to your device.

Read

This button allows you to read back the already set curve already loaded in the 123ignition on your device.

Write

This button allows you to save the custom curve in the 123igniton. CAUTION!!!  This button only works when the engine is not running, but the ignition must remain on.

Centrifugal curve

Read out here the set Centrifugal curve your received. You can adjust your curve and add points.

Edit centrifugaal curve

Set your values here and add a dot if necessary.

MAP curve

Read out the set MAP curve you received here. You can adjust your curve and add points.

Edit MAP curve

Set your values here and add a dot if necessary.

Centrifugal Curve

Static advance:
The value entered does not change the behaviour or progress of the 123\Tune+. The value is only used to adjust the overall advance in the app’s dashboard. This can be nice if, for example, the ignition is set to 10 degrees before TDC, but you want to see the advance relative to TDC. The total advance in the dashboard is then the 123\Tune+ advance plus this value.

Enable rev limiter:
Here you can turn your rev limiter on or off.

Rev limiter treshold:
Here you can set a limit for your rev limiter.

Settings

Once you can select a device under Devices, you can connect by pressing it. When you connect to your 123Button+ for the first time, the password is: 1234
You can always change this later, of course, by clicking Change pin.

Under Immobiliser you can operate the Immobilize your device button, once this function is on, the car will spark a few times at low revs, but will soon stop sparking. This function is meant to make sure that not everyone just drives off in your car. And the reason the 123ignition does give a few sparks at low revs is to distinguish that the 123ignition is not broken.

We walk you through them all.

Display always on:
This setting ensures that your screen does not go into sleep mode, This can come in handy if you want to use the 123Tune+ app for long periods of time without the screen going down.
