I’ll try one out on the buggy if you don’t get any feedback. Refresh my memory in a few days and I’ll order one.

Its too bad that there is no more info(specs) for this.

Its too bad that there is no more info(specs) for this. Yep,I agree!Lots of BS but no actual testing of what the curve actually is,,Would be nice to know if it does work...

NEVER REMOVE THE EZ-CODER "Magic-spark" Seems pretty legit. As long as the magic is strong enough to get through the shielding on the plug wire.

I have a Kitaco adjustable CDI from the Roketa. AC. Still, it gets the point across that it sucks and adjustable can mean various things. Mostly the dial just moved where the advance happened. The TaoTao had to take on test duty for this CDI since the timing light won't cooperate on the Roketa. The neighbors probably didn't mind not hearing the chambered muffler revved for an hour. It bugged me not knowing what the CDI does with more certainty, even if it didn't give me any more speed. Here's the Roketa's stock "Zonko" CDI. As cwazywazy said, the dial on the Kitaco CDI does change when advance happens. It also makes a bit of a change to idle advance. Since it's tougher to read on charts, the Zonko CDI climbed from 14° BTDC at 1500RPM to full advance of 28° by 4000RPM, or 14° over 2500RPM. The mildest setting of the Kitaco CDI was all the way clockwise. There, it stayed at 12.5° until it started advancing around 6000RPM and climbed to a peak of 27.5° by 7000RPM. In the center, the Kitaco stayed at 14° till just after 2500RPM and advanced to 28.5° by 4000RPM. The most aggressive setting, counterclockwise, started at 17.5° at 1500RPM and rose to 28.5° by 2500RPM. The clockwise setting of the Kitaco may reach the same advance as the other settings, but I think my timing light may lag at high revs. I've seen that behavior when doing other CDI tests. I never actually checked the first settings all the way to 7000RPM because just revving and watching I could see that timing wasn't really changing. It's pretty clear why I saw no gains at speed with the CDI, since there's only about 0.5° difference in stock and it's full advance. I thought it felt a little peppier at low throttle, but really didn't spend much time there and wasn't certain. It probably was, based on the timing numbers. I should note, this is what it's doing on the TaoTao. I suspect it is very similar on the Roketa, because both have the pickups modified and moved to the max advance that they allow, which is usually 2-3°. In case anyone wants to compare, here is the chart from Project TaoTao when I checked it's stock CDI vs Scrappy's blue and orange CDIs. At least this Kitaco does indeed have a curve, rather than a pretty much flat line.

I took the plunge and ordered one of those about a week ago, still waiting for it to ship.

Only the 2T guys have commented here, we need to get back on the other side of the fence.

Only the 2T guys have commented here, we need to get back on the other side of the fence. it's ok. Even of the 4t guys see us, theyre too slow to catch us. Unless they got the magic-spark

Any updates on these boxes? The one from Ali?

Ive found with all the "adjustable" or "timing advanced" CDIs only adjust the idle advance / ramp in rate as 90gtvert said. A lot of the orange "performance" CDI boxes simply get rid of the ramp in and set timing to 28 degrees across the whole RPM range.
The only real way to advance the ignition timing on these gy6 engines is to slot to pickup coil and physically move it for more total advance or buying a flywheel offset key which does the same thing.
Unless there is some microprocessor based CDI that can predict the next spark event based on RPM and timing that i dont know about, even then that would be an extremely finicky system. What we really need is a toothed reluctor wheel with a programable CDI to go with it
