Ignition Thoughts/Ideas/Recommendations

[NoDOHC]

The toggle doesn't help me at all, as it still uses a common line to send out the ignition signal. This means my coils still get a drastically too-short charge time, even while being nowhere near to being saturated.

At 9,000 rpm, I get a maximum charge time of 2.8 ms (3.3 ms - 0.5ms discharge time). This will barely fire the engine.

Example of ignition signal:

3000 rpm
------------Leading -------------------Trailing--
___________|---------|___________|---------|

6000 rpm
--Leading ----Trailing--
_|---------|_|---------|

9000 rpm
-Leading-Trailing--Leading-Trailing
_|-----|_|-----|_|-----|_|-----|

Both the leading and trailing coil take a similar output from the ECU (just differing in the split angle), Thus the toggle signal is meaningless for the signal.

What I need is a "Smart" ignition system (that controls dwell independant of signal charge time). I can easily build a circuit that divides a signal to multiple ignitors based on the toggle output.
