16.2.1.4 EFI circuit diagram:
16.2.1.5 Note for use of ECU:
1. Do not place ECU in the high temperature parts, such as a muffler or engine;
2. The ECU cannot be placed near the water droplets, oil or any liquid;
3. Do not let the mud or other contaminants cover the ECU, affecting the ECU cooling;
4. Use the M8 bolt for connection and ensure that the tightening torque is about 3.9Nm; installation
surface must be flat to prevent bending the circuit board caused by external forces to ECU.
5. The ECU normal DC power supply and voltage range is 9 to 16V, and the ECU does not produce
permanent damage if working under no more than 26V DC voltage for one minute, and so is it, if
working under the condition that the reverse voltage does not exceed 13V DC voltage within one minute,
will not cause permanent ECU damage.
