What does a scooter CDI do?
The CDI is like a computer as it controls the engine of your scooter. It instructs the fuel injectors when and for how long they should spray. It also directs the spark plugs on how to perform especially when they have to fire. Thus, it’s unable to store enough voltage to keep the engine running.
Can you start a scooter without a CDI?
Yes, you can with a mechanical unit. But customizing one will take lots of time and effort. It might be even more costly to custom build one as the CDI on the market shelf is mass produced one hence efficiently produced.
Which is better CDI or ECU?
Most CD ignitions are made to give very high output voltages but this is not always beneficial. When there is no triggering signal the charging circuit is re-connected to charge the capacitor. The CDI referenced in some models of Polaris is controlled by the ECU (electronic control unit).
How does the CDI work on a scooter?

What does CDI stand for in ignition circuit?
What is CDI? CDI stands for capacitor discharge ignition (alternatively, “capacitive.”) If you’re new to capacitors, they’re similar to batteries in that they can store energy for later. What sets them apart is their ability to release all that energy near instantaneously, which is ideal for an ignition circuit. Here’s a CDI box in a dirt bike.
What do you need to know about a CDI?
A typical CDI consists of a charging circuit, small transformer, a main capacitor, and a triggering circuit. The system raises a voltage of 400-600 volts by the transformer. This current is then channeled to the charging circuit and to the capacitor. The charging unit has a rectifier to prevent discharging before the ignition is executed.
Why does a CDI unit need a capacitor?
CDI units, also known as Capacitor Discharge Ignition is the same electronic ignition system, but in place of using a coil and having the coil create its own spark, here the ignition is provided by the capacitor charge. The reason this is used is because the coils take a long time to collect charge…

How is the capacitor charged in a CDI module?
A regular CDI module involves a little transformer, a charging circuit, an actuating circuit and an essential capacitor. In the first place, the structure voltage is raised up to 400-600 volts by a transformer inside the CDI module. By then, the electric current streams to the charging circuit and charges the capacitor.
Can a Honda scooter get an unrestricted CDI?
Tho, since performance of the stock 4-st Honda GET engine is very limited some people state different results. Don’t expect too much from installing an unrestricted CDI. Pretty much all of the Chinese 50cc scooters have a restricted CDI installed.
