PSR Parts - External ECU Remap Tuning - BMW G30 545E PSR-ECU-BMW-G3X45E

PSR Parts External ECU Remap Tuning – BMW G30 545e (500HP / 780NM)

Upgrade your BMW G30 545e with the PSR Parts External ECU Remap Tuning, delivering 500HP and 780Nm of torque. This advanced tuning solution remaps your vehicle externally, enhancing power, torque, and throttle response without altering the original ECU software. Specifically optimised for BMW hybrid engines, it ensures maximum performance, reliability, and fuel efficiency.

Unlike typical PowerBox systems, the PSR External ECU uses real-time engine data from multiple sensors via CANBUS or camshaft signals to calculate torque and power outputs. This guarantees accurate, safe, and consistent performance while keeping your engine within factory limits.

Key Features & Benefits

• Advanced Engine Management: Optimises torque and power using turbo pressure, RPM, and engine load

• Dynamic Fuel & Boost Control: Adjusts fuel injection duration and turbo spool timing for immediate acceleration and improved mid-range torque

• Load-Dependent Power Delivery: Power adapts based on throttle input for both daily usability and high-performance driving

• Turbo Boost Optimisation: Increases boost safely for stronger low-end torque and high-end power

• Fuel Efficiency Optimisation: Fine atomisation ensures more horsepower with less fuel

• Safe & Reversible: Fully reversible installation with no permanent changes to the original ECU

• Persistent Performance: Tuning remains effective even after factory ECU updates

How It Works

1. Engine RPM & Load Monitoring: Receives accurate engine data via CANBUS or camshaft signal

2. Torque Calculation: Measures engine acceleration for optimal torque and power

3. Injection Duration Extension: Fuel injectors operate longer for precise performance

4. Turbo Boost Regulation: Adjusts turbo spool timing and boost levels for immediate low-end torque

5. Load-Dependent Adjustment: Power delivery varies dynamically based on throttle input

6. Fuel Economy Enhancement: Efficient fuel delivery ensures maximum performance with minimal consumption
