Vehicle Application / Specs

• Model: Porsche Cayenne Turbo GT (Coupé)
• Platform: E3.2
• Engine: 4.0L V8 twin-turbo (EA825)
• Drivetrain: AWD
• Production Years: 2023+
• Fuel: Premium gasoline (91+ AKI / 95+ RON recommended)

Power & Torque Gains* (Crank – Approximate)

*Actual results depend on fuel quality, hardware, dyno type, and conditions.

Key Features

• ECU individually reprogrammed for the EA825 4.0TT
• Massive gains in power and torque across the rev range
• Improved throttle response and linear pedal mapping
• Top speed limiter removal (where supported)
• Raised RPM limiter within safe limits
• Optimized fuel, boost, and ignition with full knock control
• Factory safety routines retained and refined (EGT, knock, boost, thermal)
• Supports bolt-on hardware without sacrificing reliability
• Optional exhaust crackle / burbles or OEM-quiet configuration
• Datalog analysis available for in-house flashes

Software Options

Stage 1 – Stock Hardware / Mild Bolt-Ons

• For stock vehicles or cars with panel filter / intake and cat-back exhaust
• Available calibrations (example fuels, may vary by region):
  • 91 AKI (95 RON)
  • 93 AKI (98 RON)
  • 100+ AKI race fuel
• Focus:
  • Strong gains on pump fuel
  • Smooth, OEM-like drivability
  • Emissions-conscious (factory primary catalysts and OBD monitoring retained)

Stage 2 – Full Bolt-On (Track / Off-Road Use)

• Intended for intake + exhaust + high-flow downpipes / sports cats
• Recalibrated for higher flow and lower backpressure
• Stronger mid-range and top-end with suitable hardware
• Rear O2 / efficiency strategies available for off-road / motorsport use only
• Recommended only where local regulations allow non-OEM exhaust/catalyst configurations

Note: Stage 2 and any configuration affecting catalyst efficiency are for track / off-road use where permitted. Customer is responsible for compliance with local laws.

Hardware Requirements & Recommendations

Stage 1

• No hardware required
• Recommended: High-flow panel filter or intake; optional cat-back exhaust

Stage 2

• Required:
  • Quality cold air intake / upgraded airbox
  • Performance cat-back exhaust
  • High-flow downpipes / sports catalysts or performance catted solutions
• Recommended:
  • Upgraded intercoolers
  • High-flow charge and inlet pipes

Calibration Strategy & Safety

• Torque & Boost Control
  • Reworked torque model for accurate ECU–TCU interaction
  • Boost and turbo speed kept within safe operating limits
• Fueling & Knock Control
  • Rich, safe AFR under high load
  • Full OEM knock control strategies active and recalibrated
• Thermal Management
  • Protection against excessive EGT, coolant, and oil temperature
  • Power reduction logic retained for component protection
• Driveline Protection
  • Torque delivery shaped to reduce shock loads while maximizing acceleration

Tuning Method / How It Works

Option 1 – In-House OBD2 Flash (AMT Tuning, Toronto)

1. Book an appointment and bring the vehicle to AMT Tuning.
2. We perform a system scan and ECU read via the OBD port.
3. AMT uploads and programs the selected Stage 1 or Stage 2 file.
4. Road test with datalog analysis and final checks.

Typical time required: 4–6 hours.

Option 2 – ECU Mail-In Service

1. Customer removes the ECU and ships it to AMT Tuning.
2. We bench-program the ECU using professional tooling.
3. ECU is re-sealed, tested, and shipped back.
