This ECU ENGINE CONTROLLER may also be found in other Fiat models with 0.9 TwinAir engines, but correct selection must always be based on part number 51969926 and 8GSW.M3.

VIRGIN version – how it works

The ECU is prepared in VIRGIN state, meaning it automatically learns and adapts to the vehicle configuration after installation. This eliminates the need for manual programming or cloning.
