What are the common issues with the 6-speed manual conversion on the 2007 Ferrari 599 GTB Fiorano?

Question

Accepted Answer

The 6-speed manual conversion on the 2007 Ferrari 599 GTB Fiorano, while creating a truly special driving experience, does come with several well-documented challenges:

**Main Technical Issues:**

1. **Flywheel Problems** - The converted cars often use a lightweight flywheel that can make the car prone to stalling, especially in stop-and-go traffic. The RPMs drop very quickly between shifts, making smooth driving more difficult than with a factory manual transmission.

2. **ECU Coding Headaches** - The electronic control unit requires extensive reprogramming to work properly with the manual transmission. The factory ECU calibration for manual cars was reportedly "half-arsed" according to conversion specialists, requiring custom tuning to get the rev-matching and torque delivery right.

3. **Parts Availability** - Since Ferrari only made a tiny number of factory manual 599s, getting authentic parts for the conversion is challenging and expensive. Many components need to be custom fabricated or sourced from extremely limited suppliers.

4. **Cost and Complexity** - As you can see from this listing, the conversion alone cost over $104,000 ($84,990 for mechanical work + $19,551 for electronics), making it a very expensive modification that requires specialist knowledge.

**The Good News:**
- Modern conversion kits from specialists like EAG, SBR Engineering, and Out of the Gate have largely solved many of these issues
- The converted cars reportedly drive better than the few factory manual 599s that exist
- Parts supply is improving as more companies offer conversion components
