Dual map CDI on 250

[KTMAndy]

Gmp ,
l have a 05 ec 250 ,it had the dual cdi on it but no switch , l put a switch on it about a year ago , the sunny mode feels like the motor has been leaned off a bit , it is a fair bit crisper and has a slight but noticable crack to it , l like using this setting on open courses when its really muddy as the rear spins up quicker and seems to clear the rear wheel and grip , the rain setting mode ( handbag mode ) is pretty helpful when going gets tricky , slippy uphill climbs are a little better , on the whole the effect of the switch is quite suttle , worth having if you have the dual cdi fitted already , just for the record l also tried the bigger power valve cover but l found it had too much bottom end and took it off after one race , hope this of some help

Finally re-found this post! I read this with interest the first day I joined the forum, I believe I have the dual map CDI, under the seat, black wire, looped back into an orange wire on a single connector.

So next question, where do I get the switch from and how do I wire it up? What does it switch between, I,e, black wire goes to switch, and returns to??? And which wire is which?

Look forward to reading the answer, I'd like to try the dual map!

Maybe just had a brain fart, but is circuit closed one map, circuit open the 2nd?

If so, would this KTM oem part from a 2007 200exc do the trick?

Or even a straight forward kill switch.

 

[Jakobi]

Yeah mate. Any sort of toggle switch that either opens or closes the circuit will do the trick. As long is its not the kind that open again when you take your finger off the button.

Nice, just bought the switch from fleebay. Next obvious question which circuit is which? Closed summer, open winter? Or visa versa?

Closed summer, open winter? Or visa versa?

You got it.

Ive only tried switching the map-switch once when once on the trail on my 2006 250.

Not sure i noticed much difference. Maybe a bit less aggresive, and hence more grip because it was less likely to spin-up instantly.....

Quick question: Ive read alot of other map-switch users (KTM'ers ?) saying you need to turn bike off, turn the switch; then re-start the bike for the change to be effective.

Is this true with Gassers ?

No not on my bike

Cool - thanks.

First few rides i forgot all about it. When i did remember last time out, it was in a section where 'i had enough to worry about'. I then tried it on a short and pretty straight section and thought i noticed some difference [With less hit low-down] but went back to 'Sunny' setting soon after as that was what i was used too.

Its really wet, and muddy here right now, so ive stuck it on rain mode and will try it next time out.

I have never been very sensitive to small changes. So I really don't notice a difference when I switch mine on my 2010. I just leave it on the rain setting.

With my 200 in the sunny setting there is a noticeable mid range hit that tapers off slightly into a good top end.

With the switch on cloud the mid range hit is softened a little, and in the top end it seems like it struggles to rev out.

For me where the map switch works well is in really slippery mud, when I flip from sunny to cloud in those conditions there is noticeably less wheel spin, but in dry conditions not as much difference so I tend to leave it in sunny which helps the 200 get going.

The "really slippery mud" part in regards of using the rain setting sounds just what im looking for.

Because its the only ground condition we have around here right now.........

NOTICEABLY LESS WHEELSPIN sounds perfect.

keep in mind this is on a 200, the switch may have more of an effect on the smaller engine, and jetting will effect how much of a difference the switch makes
