TZR125 4DL > TZR125R IC inside the CDI

A small side step is to investigate the 3MB-00 CDI (from the DT125R)
As it has the same connections, it would be interesting to see what curve is in stored, perhaps its not that bad.

Here you have the 3MB-00 CDI

After letting it soak in fuel for a couple off days
It turns out like this

Here you have them connected on the scope.
Connected them together to show the difference

Yellow = pickup signal (for both CDI the same)
Purple = 3MB-00 CDI
Green =  4DL-00 CDI

Here a shot around the 3500rpm
3MB has more advance

Yellow = pickup signal (for both CDI the same)
Purple = 3MB-00 CDI
Green =  4DL-00 CDI

Here a shot around the 7000rpm

3MB and 4DL about the same


Yellow = pickup signal (for both CDI the same)
Purple = 3MB-00 CDI
Green =  4DL-00 CDI

Here a shot around the 10000 rpm

4DL has more advance

Have calculated the curve from the 3MB as it is in the lower revs really different than a 4DL
From 43Hz till 70Hz i calculated it with 1Hz a time, after 70Hz the usual steps

Here the two curves, as you can see ran out off paper drawing on a scale like this.
But it gives a good indication how the are
