Modified Fuel Injection

[jdzura at csc.com]

I'm interested, but I don't understand what you mean by "Variable Frequency". I
thought the EEC IV put out voltage not frequency. What does a varying voltage
caused by changing air flow have to do with frequency?  When you say you have t he
tables, do you mean the map of airflow vs output voltage for a specific MAF?

Ford EECIV map will put out a variable frequency. Have tables if you
need them
