How to duplicate Saab coil ionization signal without engine?
How to duplicate Saab coil ionization signal without engine?
(OP)
Hello everyone, currently working on a Saab direct ignition cassette. There are no difficulties to get it to fire, but I cannot duplicate the ionization signal or knock signal(obviously I cannot do both without a engine). Is their a way to duplicate the ionization current and feed it through the spark plug? For example what if I fire another coil into the spark plug, would that work?
Basically I need to duplicate the ionization current going through the spark when it's not firing.
Any thoughts or ideas would be greatly appreciated.
Thanks!

Comcokid - This is correct, but I need to confirm the cassette is receiving and analyzing the signal from the spark plug. Eliminting the cassettes output, wouldn't help me determine if the cassette is doing it's job or not. We did capture waveforms from a vehicle and tried to reload it into a function generator, which worked. But in the end I'm just basically tricking the ecu.
