Power & Torque Gains* (Crank – Approximate)
| Calibration | Fuel | Power | Torque |
|---|---|---|---|
| Stock | – | ~650 hp | ~626 lb-ft |
| Stage 1 | 91–93 AKI (95–98 RON) | up to ~760 hp | up to ~830 lb-ft |
| Stage 2 | 93+ AKI / E-blend + bolt-ons | up to ~780+ hp | up to ~850+ lb-ft |
*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)
- Book an appointment and bring the vehicle to AMT Tuning.
- We perform a system scan and ECU read via the OBD port.
- AMT uploads and programs the selected Stage 1 or Stage 2 file.
- Road test with datalog analysis and final checks.
Typical time required: 4–6 hours.
Option 2 – ECU Mail-In Service
- Customer removes the ECU and ships it to AMT Tuning.
- We bench-program the ECU using professional tooling.
- ECU is re-sealed, tested, and shipped back.
