Hi. I want a CDI circuit for a 4-cylinder engine with a separate combustion ignition coil.
Please send and guide the necessary circuitry for this by e-mail.
Tell the electrical parts you need.
Thank You

a 4cyl engine would use a single coil and a distributor. ignition timing would use a 4 lobed cam or a 4 tooth wheel and magnetic pickup.

You want one, it is easiest to buy one. Especially one made specifically for your specific car.

It is impossible to know the timing advance for high speed (or what is considered high speed on your car, or how much to retard ignition for cold start, buy one.
