If the LED blinks red
A red blinking LED indicates that SuperFlow cannot correctly detect the ECU signal.
Common causes
Incorrect ECU wire selection
The yellow SuperFlow wire may be connected to the wrong ECU wire.
Please review the “ECU Cable Location” section above and make sure the splice connector is attached to the correct ECU wire.
Incorrect splice connector installation
Verify the splice connector is fully closed and correctly positioned.
Bent yellow wire terminal
Ensure the metal terminal of the yellow wire connector is straight and fully inserted.
Engine stop switch in OFF position
Verify the motorcycle engine switch is in the ON/RUN position.
Recheck all connections carefully before testing again.
If the LED blinks green
A continuous green blinking LED means SuperFlow cannot establish correct OBD2 communication.
Standard SuperFlow enrichment (classic map) will still operate normally, but advanced maps and OBD2 functions will not be available.
Common causes
Dedicated connector not fully inserted
Verify the black SuperFlow connector is fully inserted and locked using gentle pressure only. Do not force the connector. Also verify that the internal pins are not bent or damaged.
Restart the motorcycle ignition
