Ignition coil inductance?

[Don Holtz]

Hello!

I am working on a device for testing ECM functionality.  When completed it
will be able to measure a variety of ECM parameters like injector duty, etc.

Can anyone guess at what a good "typical" primary-side ignition coil
inductance value might be?  A range of value would be good.

I need to know this because my tester is essentialy simulating engine
function while taking measurements.  So, I also need to simulate the
ignition circuitry too.

I hope this makes some sense.

Cheers,
Don
