Hi,Paul
I read information about low cost electronic inyecction and ignition.
I have an idea to improve the ignition power for a long time, i remember that in the wankel,the time of ignition is more long than a piston engine.
May be is posible to drive the ignition with a tlc555,may be with the same that works in the injection,two funtions with only one timer.

The idea is:
Work with 2 coil for plug.

Take the same signal of the sensor e-shaft and generate an signal to 38º for an coil,and other signal to 10º for the other coil.I think that this idea can work,may be with tree coils for plug also.

Take the same injection signal of the sensor e-shaft and generate an signal to 38º for an coil,other signal to 18º for the second coil and other to 10º for the third one,the degree are not exactly is only for you have an idea.

I don`t know if you tested this before.
What do you think about?
Sorry for my poor english,i hope you can understand me.
Best regards.

Good idea.

Sort of a gated oscillator. If you will design it I will build it and try it with my new ignition system.
I need six square waves with a 200 usec period starting at a ordinary VR trigger.

Use a LM1815 to handle the VR trigger.

It must work up to 10,000 RPM.

Sounds like it will work with a stock RX8 VR trigger. If it works I can test it on my RX8.
