The CDI is basically a delay machine,it counts the pulses from the
crankshaft which tells it what rpm the motor is running.
for example: if crankshaft pulse arrives 60 deg BTDC and you need 20 deg
advance then you need to delay the ignition pulse by 40 deg. so for each
rpm step you program the required delay(advance).
i designed a Cdi based on pic16F690(it wasnt perfect) but I could program different tables into it (advance curves) unfortunately i dont have a Dyno here ,so by the seat of my pants I could not see any major hp gains-sorry to disappoint you! so i concluded that the stock cdi curve was optimal.

If you want to change your rev-limiter, you can also change your entire 3d mapping for your entire ignition curve.

Buy one of these:

Technology is Great!!


Vortex nor Dynatek makes anything for the XR650L,

I spoke with Dynatek about getting a fully adjustable unit like they make for everything else and they told me a minimum order of 250 units would be necessary to make one for the XRL.

I'll take 2 of them, now who wants to order 248 more ?

Maybe someone should start a group purchase thread topic and see how many would actually be interested.

I'm also interested, but I'd like to see before and after dyno results before committing.

Ive decided Im going to buy a MSD ingition for my XRL based racer.
Seems to be the best way of getting more revs and the best midrange and top end power gain.
Ive been quoted £150+17.5% tax here in the uk. so I assume theyre about $300. Could be cheap HP!

Lead time is 4 weeks to the UK so should have the bike back on the dyno early 08. Also have a NX650 CDI (which Im using) and new XR600 CDI I could try as a comparison at some stage.

Will post dyno results on motopike.com and here


Results ???

Ask me specific questions about what you want and need for your use, and I'll tell you the options available and how to put something together. The kit form is the least expensive, but they are pre built units too. Megasquirt and Megajolt.

Thought I'd blow the dust off this one...anyone have any new ways to add more advance to an L ignition?

Megajolt offers a totaly programable 3-D mapping with MAP sensor for $84. What do you want. Maybe if the price was $10.00 you would be interested.
