I just want to note that the under 1000-1500rpms on my older graphs may not be exactly right, the graph when you start out at 0 degrees and 0 rpm ramps up to the first whole number.
I kind of lost my notes of exactly when these cdi's turned on but in the case of the new cr125-250 ignitions they turn on and start at 9 degrees of advance.
Sorry for the confusion

So the way I read it they all look very similar with the trx falling off the least.  But I am not sure how much effect these slight differences have.

Its really a shoot in the dark, honestly everybody will tell you to run a 01 cr250 but depending on your head and pipe designs any one of these can be the best.
I made the best power with a 2000 cr125 cdi with 1 degree of advance but 2 years ago my best power curve was a 2000 cr250 with 8 degrees of advance.
This is where a dyno is used to fiquire out what your combo wants, dyno's are not to tune your motor it is to test parts that work or do not work with your setup.

Well I wanted lights so I held out and waited for this cr250 ignition with lights,  but what showed up looks like a service honda cr500 ignition.  So I asked and was told the same company makes thier cdi's as well.  So I asked if the curve was the same as an 01 cr250 and I was told it is close.  I just dont know enough about this stuff. Maybe I should run it with the stock ignition then bolt this on and see the difference.

If you pay for the shipping round trip I can check it for you and post the results. I normally can get to it within a couple days of receiving it.

I want to add these maps to show you the possiabilites with differant cdi boxes yet the same amount of total timing at peak rpm.
If you look at most single cylinder 250-500cc motors in atv's they normally peak around the 8500 rpm mark.
Obviously some are less and other are more and that does not mean they do not rev more but 8500 is usually very close to the peak and the rest is over-rev.
So all these curves meet at 8500 from this while on the dyno you can decide by adjusting the stator plate or changing to another CDI to add or take away timing before and after to create a wider powerband.
Basicly any year CDI, TRX or CR can be adjusted on the dyno at peak rpm to make the exact same HP, but by changing the curve you can build power before and after peak.

Just want to add that 2002-2003 CR125 cdi need to have a external grounded kill switch circuit, the 00-01 ground internally in the CDI.
If you do not add a ground then the kill circuit does not work but the CDI will fire and run the engine.
The external ground does not effect the 00-01 CDI so once you add a ground any year box will work

Here is a 250R VORTEX these have 10 maps built in them, unfortantly during the short time I had this my bench tester burned up a circuit board and I did not get all 10 maps

I'm glad this information made it over here. Thanks for all the time and effort you put into mapping these ignitions it's been very helpful over the years.

Thought I would post up Jim's CR250 ignition with a lighting coil timing curve compared to the 2001 cr250-cr125

System seams to be of a nice quality not sure who builds it but it does seam to be the same manufacture Service Honda uses for the cr500 ignition.
When I went to the Service Honda website the wire schematic matched perfectly and looks to be simular.




here is a picture of the BDT flywheel compared to a 2001 CR250 flywheel, BDT's flywheel has a 200 gram weight added to it.
That would make the the bike feel closer to a stock style flywheel but probably still rev quicker since its much smaller diameter

Thanks Dan!

here is what the CDI and stator look like along with the adapter plate
