There is two map sensors on the bikes with the melco ecu
Generally when the sensor is defect , the engine run rich on 1 cylinder and stall time to time.


i've faced this problem recently and no dtc codes were thrown because electric characteristic of this sensor was good, but it wasn't sending any information to the ecu


how to check if your sensor is working:
1- start melcodiag and wait it finish to initialize
2- open passive test tab
3 - tick refresh in the frame where MAP V MAP H is displayed
4 - start engine


now as the engine revs , you shall see values of each map sensor been refreshed .


if the value is still the same , never refreshed , so your sensor is broken
