The ultimate ignition system

I have an update. Today I was able to do a 2 channel scope of my car like I talked about. Here is the setup:



Here it is physically:




Here are the results:

Idle:



See how the voltage waveform drops as the current levels off? This is the max primary current I was refering to. The ig module limits the current in the primary to avoid overheating of the coil and the ig module. Then as the primary current drops to 0 the voltage on the primary reverses, indicating a spark has been delivered.

reved up:


It's essentially the same, only there is no current leveling off. This is because there is no time for the coil current to reach maximum. It also means the spark energy has been degraded somewhat at this rpm (4k or so).

I'll let you know as soon as I do it....   :)
