MOPED ARMY

yeah 2013 does not retard it advances (too much) with the yellow cev coil but it does retard with the red motoplat coil and on treats cdi... looks like eds been right... power is in the coil and the box.

Well he states that it does retard, im pretty certain he is stating that you need a "good" external coil.

There made for argentina moped NOT european. So you must hack them.

good look, on trying to clear up the problem but there is no problem just need to test every else combo.

There not a racing cdi. I was mistaken so long ago. There a replacement to get rid of the points and condenser.

Its all about the magnetos.

Tell me why the bosch 06 w/2013 cdi package has a curve on the v1's.

You haven't seen my youtube video of this cdi? (edited)

Curve advanced or retarded?, im on a crappy work machine so I cant watch. On my 04 with a cev stator it retards... Dunno. It is a company in which I have received a brand new green unit and 2013 box that doesn't work at all so im sure there are some variances in quality.

Most of the zanella came with motoplat magnetos. I do not know how long the dze or cev was used. I would timing light everything and video it. Just search minarelli v1 peitcard on youtube. Let me know what you think.

Wow, brand new and doesn't work. :(

I can't understand either the original pietcard guy, nor ed. i'm so confused. I don't even have a minarelli anyway so i dunno why i care, or why i'm writing this.

Anyway, good stuff to know, thanks guys

Woot, finally something specific:

Mike, when I say until 10.000 it mean that the CDI can broke up 10.000 RPM.

If your motorcycle work more 10.000 you must to use the CDI 2041 with the correct proper coil.

The proper coil depend the magnetic wheel and the rotating engine.

You can see our webpage in the serie 100.

Any question please tell me.

good to know.

Have you tested the blue one yet? Should test it and take video of the curve. I have one also I need to get time to test and see if has a curve. Different magnetos are going to do different things. Watch the youtube.

the timing advance/retard on these analog systems is based on the current pulse coming in. The more powerful pulse, the faster the CDI circuit triggers, meaning the faster the engine is spinning, faster magnetisim change, higher magnetic flux, faster spark (more advanced).

this is weighed against the internal components of the circuit (capacitor and inductor) which result in a phase lag as the frequency increases, this makes the spark more retarded.

the two effects are occurring simultaneously in the circuit, and fighting against each other, so having the box work consistently is a delicate electronic balancing act. If one coil has more windings than the originally intended coil, the advance will win because the increase in power is outweighing the lag of the circuit, if you use a less powerful coil the circuit will lag more (generally speaking) because now the capacitor is winning. If you start mixing and matching crazy different boxes and coils that aren't made for each other you will get totally unpredictable results. the only way to find out is doing a lot of testing, or cutting everythign apart and modeling it (very time consuming, but i'm working on doing some of that).

i'm sure pietcard has designed certain boxes to work on certain coils and do certain things, perhaps using the minarelli coil the 2013 will do some retarding, but the bosch coil is too powerful and makes it advance or not retard... the 2041 would have different capacitors and resistors to make the bosch coil work.

without knowing the coil output waveform, the circuit schematic, and doing some modeling/simulation there is no real way of 'knowing' what combinations will work in what way. Even the magnetivity of say, a peugeot flywheel vs a bosch flywheel, will give totally different responses. given the response that pietcard gave, they probably are using 'rule of thumbs' or perhaps the only guy that speaks english has better things to do that explain all that to us.

also: for awhile i was trying to figure out if i could use a china pocket bike motor CDI on my tomos A55 1 wire ignition (early revival)... the answer is yes, they do work, but the china CDI is so crappy that it advances dramatically after 5000 rpm... this is probably what the stock (bad) tomos ignitions do, and thats probably what the pietcard does, or maybe it just cuts out... ach! need more testing!

You could experiment with the air gap between the shoes of the coil spool and the rotating magnets. Maybe even elongating the slots the attaching screws ride in.
