OK well I here a lot of people want a Programmable CDI I am going to start development My Idea Programmable Via Blue Tooth/USB Integrated CHT monitor view able on an android device IGN timing View able on android device with real time adjustments Limited to prevent eng damage Possible knock sensor? Ability to add a fixed LED timing light and add permanent timing marks to ad an interesting look to the iggy side of things and a connector for an external Timing light. Starting some software development soon. And so on I am going to start an extensive development for this as I think this will be good especially for tuning I hope in the future I can create firmware that will monitor CHT and knock and retard timing or cut spark. What do you all think? Started to collect hardware and still need some more but I am going to enjoy this one. Of course a knock sensor System for a scoot would be much easier and the micro controller based CDI can also measure the sensor with ease. Thank you for the idea 190Mech!!!!!

This looks like a great project and I hope you do it "right after I get my frame".

Alrighty!Now you are talking!!Most of the race bikes have a 'deto sensor' light,that reminds the pilot to keep the light out or he'll highside in the next big sweeper when the motor locks up!!

John just hearing the term "high side" make countless places on my ancient abused body ache.My problem could not have been cured in my active racing days due to a congenital disconnect between my right wrist and my brain.Think I have finally made the decision to retire from the track and stay that way.4th attempt and there is no 12 step program for racing addiction that sticks.

Frank,Us old guys have "been there,done that",so we build stuff for the young immortal punks and send them to the track..They think they got it good,,we Know we got it good!!

Sounds like a great project! Microcontrollers are just insanely cheap now.
The timing pulse waveform from the pickup coil can be seen in some timing discussions. It is like a periodic sine wave pulse, not a saw tooth waveform. Some CDI units use the rising edge as a trigger, some use the falling edge. If I remember correctly the stock CDI boxes use the falling edge.

Please throw 2 models on the drawing board,,AC-CDI & DC-CDI...Thank ya!!!

Sounds an awesome idea. As someone who does not like modern tech. But got seriously sideways and thrown out of the seat in the rain a couple of weeks ago. I am coming round to the idea that any tech might be good.

Please throw 2 models on the drawing board,,AC-CDI & DC-CDI...Thank ya!!! Will do buddy I am planning on trying to use the DC CDI with a regulator+Capacitor (DC Smoothing) for the AC Model only because the AC Version Uses voltages to high for Micro controllers. the cool thing about using the REG-Cap is you could still run with no battery. These sensitive electronics need a nice clean DC with minimal noise. Sucks I have handfuls of these Micro controllers that wont work lol Mine are 12C508 They have a fixed oscillator Frequency and no Counter No go. The ones I need are 12F683s they have A frequency counter and an adjustable output frequency the 2 most important things for Timing. 12F683 Good thing Frankenmech is right about them being cheap. The whole CDI cost about $25 to make even with all of the added Sensor support and BT if I can get some prototype boards made and a nice case to close and seal No epoxy could send out some to beta testers and sell em for like $45-50.

KEWL!!!The DC CDI is the part of choice for the road race crowd,spozed to be a more stable/controllable system..

I think you should make an AC DC CDI and call it the "Back In Black" CDI.
OK, just kidding.
Sorry,
