IS that what I should understand ?

The F/IC is a Fuel and Ignition Controller. The stock ECM does all of its normal functions and the F/IC sits on top of it to provide the ability to add fuel and pull timing where necessary.

It is of little use with a NA car, but a device of its nature is required when adding FI to compensate for the additional air with proportionately more fuel.
