The late 301 TCUs are in short supply and Ferrari have made them a restricted part. Hopefully that changes over time and the short supply is just due to a lack of demand...it's the reason I stocked up on them for my car.Update - only one 599 TCU is left in stock for the 599 at the factory. Although for the later gen car like mine it is only gtb spec i.e. SuperFast 1.
Back in the day the HGTE upgrade was a TCU as opposed to the engine ECU which was a reflash so...
Looks like a breaker will be the way to get my hands on one unless someone can reflash with the appropriate software.
Mark have you been under the skin of these software versions?
...same as 16m / scud?
Your car has 'SOFAST IV with Superfast shift' which is based on the CFC301 - the same as MY08 F430/Scuderia/16M - which supports flashing via diagnostics. It is typically 100ms but can go down to 85ms on the 599. Your car will support the software change (85ms) on the current gearbox and F1 hardware.
I will be pleasantly surprised if Ferrari will flash software not associated with your VIN; my understanding is every software request is verified and authorised by HQ.
SOFAST IV with Superfast shift 2 has a multitude of hardware changes to support 60ms, but you're not looking at that.
