The 123Tune+ app is designed for configuring and tuning the 123Tune+ 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 123Tune+ 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 ignition 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 idle speed and select different driving curves.
4. The app also provides graphical views of the ignition timing and other parameters for easy reading and comparison.
5. After you receive 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 and 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 123Tune+ 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 receiving a connection to a device(smartphone or tablet). You can connect to your 123\Tune+ in the 123\Tune+ application 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 receive 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 that are near the 123ignition and receive the 123ignition app (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 receive connection to the 123ignition+ 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 advance) 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 Advancement (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.
Ported or Manifold vacuum?
- Ported vacuum is a connection on the carburettor as in SU carburettors.
In the idle position of the carburettor, the vacuum connection to the ignition is closed to prevent vacuum advance at idle speed.
- Manifold vacuum is the vacuum connection directly connected to the intake manifold, so even in the idle position of the carburettor, there is vacuum to the distributor. Since the 123\Tune+ ignores these values around static rpm, it is still possible to use vacuum advance this way, even with other carburettors such as Webers.
Are you looking for advance 's / vacuum curves for your car?
Unfortunately, we do not receive the unique curve ready for every car/engine/model. But on our website (www.123ignition.com) we receive many example curves for many types.
All our 123Switch models receive a curve table, from there you can make a good basic curve.
What the right advance 's 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 receives. You can also always consult your local 123dealer, they often receive a lot of knowledge about specific brands and curves.
