Ignition Module Input/Output
 

Does anyone know the specifics of the SVX Ign. Module.
Input voltages, output and dwell, volts, mA to fire coils ect.

I'm going with stand alone engine management.

Thanks

Anybody?

Has anybody scoped the input?

I guess I should answer my own question in case someone else is going stand alone and wants to retain the factory module.

I purchashed an oscilliscope and took some readings.

The module recieves a 4.0V - 4.2V signal from the computer.

The dwell @
Idle is 2.4ms
1000RPM is 2.4ms
2000RPM is 2.2ms
3000RPM is 2.0ms
4000RPM is 2.0ms
5000RPM is 2.0ms

Now I have to find out the crank and cam sensors.
Like at what degree is the crank at when the tooth is lined up with the sensor.

Would anyone have that information?

Also the IAC valve is it votage or PWM?

I pulled my IAC off and played with it some. With pin B grounded, 12V on pin A closes the valve completely, 12 V on pin C opens the valve completely, and with no voltage applied, it rests somewhere in between. This "in between" position is adjusted by loosenening the 2 screws on the "electrical" part of the IAC and rotating it.

My guess is that at any given time EITHER pin A or pin C has a 12V PWM signal on it. (PWM means it switches rpaidly between 0 and 12 V, and the ratio of high to low determines the shutter position). Is there anybody out there who knows or can check ?
