TUONO 1000
STARTING
The ECU will only enable starting when it recognises V990
engine model based on a CAN acknowledge message from
the instrument panel (model information is located in the
instrument panel).
Only the fuel reserve sensor is connected directly to the
instrument panel. All other sensors/switches are connected
to the ECU and the instrument panel reads relevant
information in the ECU through the CAN line.
