IQA / IMA CODE PROGRAMMING, EMS ECU RE-PROGRAMMING/FLASHING
An ECU controlled engine needs precise metering of fuel. Due to manufacturing tolerances, each injector deviates
slightly from its idealized behavior. Thus, each injector has a correction factor, which is engraved on top of it, in the
form of a 7 character alphanumeric code. This is known as an IQA code / IMA code. For optimal performance of the
engine, the ECU needs to know the IQA code / IMA code of each injector. This information is programmed into the
ECU when the vehicle is manufactured. However, if you need to replace an injector(s), then the IQA code / IMA
code for that new injector has to be updated in the ECU.
As a first step, you need to select the cylinder number of the injector being replaced. After the cylinder number is
selected by clicking on the check-button next to the number, the IQA code / IMA code should be entered in the box
provided.
Click the button to the right of the text box. If the Injector code is valid and accepted by the ECU, a message is
displayed, indicating that the operation is performed successfully.
A message "Invalid IQA code" will be displayed, if an incorrect IQA/IMA code is keyed in. IQA codes are case
sensitive.
.
PLEASE ENSURE TO PROGRAM IQA/IMA CODES WHEN YOU REPLACE AN INJECTOR, ECU or ENGINE.
