Overview

The AMT Tuning Stage 1 and Stage 2 performance calibrations for the Ferrari 355 are custom-engineered reprograms of the Bosch M5.2 ECU system. Each ECU is read, modified, and rewritten individually using our bench flashing process for precise and reliable results.

The tuning process optimizes key parameters such as ignition timing, fueling, throttle response, torque management, and cam timing. The calibration is individually adjusted to suit additional upgrades like sports exhaust systems, high-flow catalytic converters, or upgraded cold-air intakes.

Key Features

• Optimized for 91 Octane / 95 RON fuel
• Rear O2 Delete (DECAT) for catless or race header setups
• Improved throttle response and engine drivability
• Enhanced fuel efficiency and mid-range torque
• ECU individually reprogrammed using bench flash
• Test drive with datalog analysis included for in-house tuning
