Air/Fuel Ratio Learning Control System
By keeping track of or learning feedback control signals sent by oxygen sensor, the SPFI system is able to automatically make corrections. This system stabilizes driveability by maintaining original performance values.
CAUTION:
Never connect battery in reverse polarity because SPFI control unit will be destroyed instantly and fuel injector and other parts will be damaged in just a few minutes more. Also, DO NOT disconnect battery terminals while engine is running because a large electrical surge will be generated. This surge, may cause damage to electrical components.
