Connecting to an injector
This image shows the connection of one injector (controlled on ground side) and one fuel level
sender.
•
When injector is controlled through ground, select “Injector High” in Setup.
•
When injector is controlled through positive side, select “Injector Low” in Setup.
Ensure that you enter the K-factor relevant for your injection timing.
Note that the injector control signal makes also a very good signal for RPM measurements on
MGL’s instruments.
