my first working cdi with advance
 

Hi people, I just want to show you my own CDI system with advance timing programmed. The microcontroller is gradually advancing from 2000rpm to 6000rpm where it gets full advance (adjustable in real time from 0 to 33.5 degrees) so I can look for the best point with the trim while the engine is running. It works fine with 4.8V or 6V, 550mA it's enough (power consumption 220mA). Easy start and no kickback (retarded), good spark up to almost 30.000 rpm. Total weight is 5.8 oz
It's working fine on my converted Stihl 60cc, I'm going to test it on a G-23 soon.

I just wanted to show you, it's my first working unit and I want to test it harder before build more. I will let you know when done, sure the first units will be at low price, I need people testing the unit on different brands and sized engines. Sorry about my poor english :(

RE: my first working cdi with advance
 

Thank you for sharing your project.

Your English is fine. I wish I were so lucky to communicate that well in Spanish!:D
I would be interested as well in prototype.

Is the braided outer insulation wire attached to the compression ring on the spark plug?

De que parte de Argentina eres??
Yo voy el 4 y 5 de Diciembre al evento del Club Newery en Buenos Aires.
Si estás por allá tal vez puedas llevar tu encendido e intercambiamos ideas.
Estoy usando encendidos de varias marcas.

Mikenlapaz, the braided wire can be attached to the spark plug's body with a fastener after install the spark plug on the engine, or directly to the engine's body. In the picture is attached to the spark plug with a plastic fastener just to test the unit without the engine.
Tatolazo estoy viviendo en Buenos Aires y con seguridad voy a asistir al encuentro, serÃ*a un gusto intercambiar algunas ideas y espero tener el cdi ya bien probado para poder mostrártelo. Saludos.

El agujero en la caja plástica es para regular el punto de la chispa con un potenciómetro como lo tiene el sistema pro spark??

(The hole in the plastic box is for timing regulation with a potentiometer as the Pro Spark system??)

saludos.

En la foto mi experimental con un Ryobi 31 cc standar. Como cuando me preguntaban el nombre respondÃ*a "No sé"por que no lehabÃ*a puesto ninguno, mis amigos del club lo llaman el "NO SÉ de dos metros"

RE: my first working cdi with advance
 

Exactamente por ese agujerito tenes acceso al preset donde regulas el avance que quieras, desde 0 grados hasta 33 (con el sensor en 35 grados antes del punto muerto superior). El avance trabaja gradualmente, hasta 2000 rpm esta en 0 y luego adelanta progresivamente, de 6000 rpm en adelante ya trabaja con el maximo avance seleccionado con el preset. Ahora te contesto el pm.
(In the hole is the potentiometer to set the max advance from 0 up to 33 degrees)

Este es muy interesante. !Bien hecho, y quiero uno! Puedo checar como funciona en una maquina de Homelite 25cc, Homelite 30cc, y Kioritz 25cc ahora. Luego con Poulan 42cc, y Ryobi 31cc. ?Cuando va a tener unos para vender o para gentes a probar?

Gracias,
AV8TOR

RE: my first working cdi with advance
 

We all would like to share,,,, english please.

RE: my first working cdi with advance
 

Good spanish av8tor! Well done! Very interesting you have many engines to test. I'm working on details, I hope soon it's done and I'll let you know by pm.
Antique sorry my english is poor and there is too spanish talken people here, we too have dificulties to read and write others languages than spanish.

RE: my first working cdi with advance
 

Ok, thank you ZiLoG Z-80, I will wait for your notice.

Your English is very good. Do not be afraid to use it. Thank you for the compliment on my Spanish. My wife is Mexicana.

Good luck,
AV8TOR

Muy bien Zilog esto es lo que necesitamos para nuestras conversiones! ya pensaste en cuanto lo vas a vender si es que funciona como esperas?, yo tambien me quiero apuntar en el equipo de pruebas, mantenos al tanto de los resultados que obtengas. Aqui en Tijuana Mexico tambien volamos conversiones y nos gusta compartir experiencias con companeros lejanos como tu y tatolazo, por lo pronto ahi nos estamos comunicando, Hasta luego. Aeo Nut.

RE: my first working cdi with advance
 

Hola Aero Nut, claro que los voy a mantener informados y es un gusto estar en contacto con México también.

RE: my first working cdi with advance
 

Geez, no puedo entender lo que usted los tipos dicen aquÃ* ... por favor use el inglés.

RE: my first working cdi with advance
 

SANTO DOMINGO TAMBIEN ESTA MUY PENDIENTE E INTERESADO EN LOS RESULTADO.

WALDO

RE: my first working cdi with advance
 

O.k. dann wollen wir Deutsche gebrauchen...

RE: my first working cdi with advance
 

Woody Aero Nut said they also fly with conversions, he's from Mexico and want to be in contact. I said is nice to meet him. Mangolo said Santo Domingo is interested too, waiting news.
Did you try translate with google?

RE: my first working cdi with advance
 

and what coil are you using?

dave

RE: my first working cdi with advance
 

I use lightened coils,think are from XR. I get spark gaps up to about 4mm

RE: my first working cdi with advance
 

Gott im Himmel, es ist eine ziemlich ordentliche CDI Einheit, die Sie dort haben.

RE: my first working cdi with advance
 

Thank you Woody
