PSR Parts External ECU Remap Tuning – BMW G30 530e (350HP / 520NM)

Unlock the full potential of your BMW G30 530e with the PSR Parts External ECU Remap Tuning, delivering 350HP and 520Nm of torque. This advanced system remaps your vehicle’s ECU externally, increasing power, torque, and throttle response without altering the original ECU software. It’s designed for optimal performance, reliability, and fuel efficiency, tailored specifically for BMW engines.

Unlike standard PowerBox systems, the PSR External ECU uses real-time data from multiple sensors via CANBUS or camshaft signal to calculate precise torque and power outputs. This ensures safe, consistent, and usable performance while maintaining engine integrity.

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 smoother acceleration and improved mid-range torque

• Load-Dependent Power Delivery: Power adapts based on accelerator input, ensuring both daily usability and high-performance capability

• Turbo Boost Optimisation: Increases boost safely, providing more immediate low-end torque and strong high-end power

• Fuel Efficiency Optimisation: Fine atomisation improves combustion efficiency, allowing more power with less fuel

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

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

How It Works

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

2. Torque Calculation: Measures acceleration rate to optimise torque and power delivery

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 and high-end performance

5. Load-Dependent Adjustment: Delivers the right amount of power depending on throttle input

6. Fuel Economy Enhancement: Efficient fuel delivery ensures more horsepower with less fuel consumption
