    PM me your email, I'll send you the Maserati academy doc:

    but

    MASERATI M139 Duoselect, EUROPE version
    HW CFC 231 (SOFAST II) up to assembly 18821
    HW CFC 301 (SOFAST III) from assembly 18822
    HW CFC 301 (SOFAST III+) from assembly 21925

    It doesn't look like you can drop in a CFC301:

    SOFAST III transmission control system (CFC301): the introduction of Sofast III involves a new control unit and the introduction of a longitudinal acceleration sensor
    and a clutch pressure sensor. The longitudinal acceleration information allows a gearchange and clutch management influenced by the vehicle dynamics. The clutch pressure information allows the ECU to calibrate the clutch diaphragm spring characteristic. These modifications resulted in a much improved clutch management.

    Current or the possible swap?

    Page 94:

    SOFAST III+ transmission control system (CFC301): identical to SOFAST III but with modified clutch and new operating software for further improved cluch management.

    Either way, I'm not feeling a swap is workable. Still, I'm hardly an expert!

    Okay so I’ve worked out using the chassis build number that my particular car is a SOFAST II with CFC231 Tcu. 2nd generation.. it also appears that I’ve purchased the same variant TCU with matching part numbers and CFC231 II but was fitted to a SportGT 2005. So this must be one of the last 231 units units before the ZF gearboxes... ur info has been a gr8 help. Thank you

    And this sort of information and detail makes my wife laugh in derision. To her a Maserati is 'just' a nice and fast car...but she's learning... Lol
