Hi guys, i have EG civic sedan, i m running custom chipped ecu, well car is fine, no cel light, well my cel light show up everytime i decelerate, ( 1 long,7 short). cluster is working fine, vtec do engaged only when no cels. vss senor and grip seems fine, cluster to ECU is wire also good. what else it could be?

 

figout that VSS sensor was not intact, just tight it up after cleaning and greasing again. wait for test drive now.
