E30 - M20 - ICV Factory Frequency Setting

[E30Bastard]

I have spent far too much time searching the forums for this simple answer.

This is what MS2 says:

"Frequency to operate at. This varies with valve type. Ford/Bosch valves typically operate 50-100Hz. Miata valves are closer to 300Hz.
Be aware that above 78Hz the output becomes less precise."

Does anyone have a definitive answer on what the factory M20 ICV hz setting in MS should be?

Can you download the starter tune and check? I don't think I have ever adjusted that, whatever setting the starter tune has works well.

120hz is what i use based on what people measured/tested on the old e30tech forums
