IQA (Injector Quantity Adjustment) means adjusting fuel injection quantity difference between injectors which occurs in-
evitably at manufacturing process as allotting serial number consists of 7 letters to each injectors.Inputting IQA code of
injectors installed in each cylinder to ECM, ECM recognizes the fuel injection quantity difference between each injectors.
ECM adjusts every injector to have same fuel injecting characteristic as recognizing specific fuel injection map which is
different for each serial number.
