What's Inside a Cheap CDI? YouWon't Believe It!

[@preflyt9124]

I dont have any clue what is cdi about but this video is on my algorithm

[@TheSimoc]

While I dislike most technical implementations of KZbin, one of its best things is to bring you new items of interest. FYI, CDI is Capacitor Discharge Ignition, a type of ignition system in gasoline engines.

[@preflyt9124]

@@TheSimoc yeah i'd prefer finding new interest instead of useless things. Also thx for the information

Its part of the motor bike ignition system. The thing making your bike sparkplug fire in a combustion chamber.

[@dpforth]

What about spark advance with yours and the other CDI boxes?

[@Spark-Hole]

That s the difficult part

[@MrWolfDiy]

Hi, Only CDI units with microcontrollers have advanced ignition timing, while the others only have different spark power with limited timing advancement, ranging between 5000 and 12000. In the future, if I can, I will design an advanced model and share it.

[@TheOriginalEviltech]

@@MrWolfDiy Original cdi units for bikes up to 1995 have analog integration circuitry that is used for spark advance. They also have spark retard to prevent kickback on kickstarted models. It might be easier to go that route, because i have had lot's of microcontrollers fail way too quickly in high impulse currents environment...

Chinese CDI units can be bought for as little as £5 UK ATM. I stipped a unit similar to the one you had which also had ceramic filling. It would not cut with a hacksaw so I soaked it in thinners for several days allowing it to be dismantled. The component's were of very poor quality so you can understand why they fail so easily. I have made several CDI units which were reliable but gave no improvement to the strength of the spark as it's governed by the power available to charge the CDI capacitor. I didn't use a drilled PCB but simply stuck small squares of PCB to a back board to mount the component's to. My 50cc engine produces 120VAC at tick over dropping to 50VAC @ 35mA at maximum revs. Thanks' for your video's Chris.

[@Herr_Bone]

Many CDIs have a function to limit the rpm of the engine - and thus the speed of the bike. It would be interesting to find replacement CDIs that do not have this throttle function. Maybe you want to talk about tuning options in another video.

[@MrWolfDiy]

Yes, that’s correct. In the future, I plan to discuss this topic in more detail, including how to control the RPM or make it unlimited. good luck

[@kurjibhalsod3547]

My bike have two ignition coil, what values of capacitor and diagrams of circuit you can suggest?

[@MrWolfDiy]

It depends on the type of your motorcycle. If your stator is AC with one trigger, you can use a dtsi CDI, which I haven't made yet. You can also use a separate CDI for each cylinder. However, if your stator is DC, you need to use a DC CDI. I made a video in two parts on this topic. (DC)The first part explains how to build it, and in the second part, I explain how to install it on multi-cylinder motorcycles. Give me more details about your motorcycle so i can see what might work best for you.

[@bencapobianco2045]

You are a very smart man!! I wish I could understand CDI’s and build one with an Arduino for my 1998 Yamaha 350 Warrior that is programmable. I will keep watching and maybe one day I’ll feel comfortable enough to try it. Thank you for sharing all of your knowledge!!!!!

[@MrWolfDiy]

Thank you so much bro, In the future, if l can, I will definitely build a microcontroller-based CDI. I wish you success.

@MrWolf, I'm from Philippines and want to learn about in making this kind of CDI, that stator and magneto is from tmx right? correct me if I'm wrong, is your CDI can work on both AC and DC motors?

[@MrWolfDiy]

DC CDI is different from AC, it depends on your application.

I refuse to purchase a CDI which circuit is hidden by black epoxy. There is a 6 dipswitch type, the dipswitch chart provided is difficult to understand the function of timing advance curve.

[@MrWolfDiy]

There are some types of CDIs where the components are visible on the back of the CDI, showing a large number of parts and has a low price , However the main circuit operates with just a few basic components and while the rest are unnecessary... In fact, a CDI with those components and a microcontroller is both expensive and provides excellent ignition timing advance...

[@thisisyourcaptainspeaking2259]

@MrWolfDiy Agree, there are many functions that are accomplished using a microcontroller such as PIC15F along with temperature feedback.

[@vancemacd6315]

I would rather buy one from you if possible.

[@11T872]

Im planing to make CDI but i dont have to much info, There is AC to AC and AC to DC?

[@MrWolfDiy]

Before building, consider the type of CDI you need. The AC type is for alternating current, and the DC type is for direct current. It depends on the type of your motorcycle.

@@MrWolfDiy i don't need it for engine, I need it for different application, need HV DC impulse as much possible frequency that circuit can handle.

Love your channel brother what do you know about a 09 Cadillac ignition

[@MrWolfDiy]

Hello friend, thank you, The car you mentioned is considered a modern car, and like most other cars, its ignition system is controlled by the ECM. what do you want to know?

[@jimmypotts4516]

Ok the person that owed it before me lost the key and wrecked the ignition so I have another key and went through the steps to program but still won't start I have fire to the coil packs and I'm getting fuel

[@MrWolfDiy]

Based on your situation, I have two guesses: First, the issue is likely related to the immobilizer, and it might not recognize your new key. However, since you have power to the spark plugs and fuel is being delivered, there's also a possibility that the crankshaft position sensor is faulty. If this component or the timing belt in your vehicle is damaged, it would cause exactly this kind of problem. Check it and let me know.

[@kevinsellsit5584]

Not all CDI from China are created equal. I have sold hundreds and had very few failures. All mine had a manufacturer or brand on the case but some would have more aggressive advance curves from the same case. To say don't buy them is wrong. They are cheap and work well on stock engines.

​@@MrWolfDiy I'm not convinced potting it in resin is a good idea. It could possibly cool better without the resin.

[@MrWolfDiy]

Sealing with resin is primarily used for preventing short circuits and waterproofing. However, its downside is that if a component becomes faulty, it can no longer be repaired or inspected.

[@tenlittleindians]

@@MrWolfDiy It's also common to prevent knockoff versions from being copied and sold.

Ik zag toch duidelijk een transistoren andere componenten. Je kan natuurlijk zeggen dat het troep is maar er zitten net zoveel componenten in als in jouw cdi.

I’ve installed them on all my motorcycles, and they’re amazing! And because of the strong spark and complete combustion, the fuel consumption of my motorcycles has decreased significantly.I can't even remember the last time I put gas in. Try it
