I got this froma Miata forum.
"Normally, the J&S Yellow wire taps into the airflow signal. The unit is then armed to detect knock when sufficient airflow is achieved.
The mass air signal on 1.8L engines increases with increasing airflow. The J&S becomes armed when the voltage exceeds 2.75 volts.
On a 1.6L, the voltage decreases with increasing flow. The unit is armed when the voltage drops below 0.8 volts.
When you switch to a Link, you need to set the J&S up as a 1.8L, and connect the J&S Yellow wire to the MAP signal. The J&S will arm when the MAP voltage exceeds 2.75 volts, and the RPM exceeds 1250.
Temporarily disconnecting the Yellow wire will allow the unit to self arm, but to test for knock retard, make sure the RPM exceeds 1250."
What voltage dose our map give? If we use a Missing Link will our map be able to activate the J&S?
