175891 STEERING ECU (FIORANO/UPRATED) 550, 575M

No, your eyes are not deceiving you!  This is indeed a Fiorano steering ECU, compatible with all Ferrari 550 and 575M models --  but better than the original.   If you're tired of the wet-oatmeal feeling in your current power steering feedback, or never really liked the Ferrari FHP (Fiorano Handling Package) steering ECU feel, this new version might be what you need/want.

This ECU is an absolute plug-and-play upgrade for your 550 or 575M with a custom mapping:   it provides a gradual reduction in hydraulic steering boost  to about 55 MPH, and after that there is no power assist. By contrast, the Geniune Ferrari (Fiorano) ECU only provides boost to about 35 MPH, and then it drops in a stepwise fashion to zero, so it’s a very harsh, abrupt transition.

Made in the USA exclusively for Ricambi America by Maranello Skunk Works.
