High-quality, dynamometer-tested ECU tuning files.

At autotuningfiles.de, we are experts in ECU chiptuning and offer professional tuning files tested and optimized on modern engine dynamometers (dynos). Our services are based on scientific analysis, years of experience, and data-driven optimization to ensure the best balance between performance, efficiency, and reliability.

Basics of ECU Tuning

Engine control unit (ECU) optimization is achieved by targeted changes to maps that influence engine performance. Among other things, the following parameters are modified:

✔ Injection timing & quantity
✔ Ignition timing optimization
✔ Boost pressure adjustment for turbo engines
✔ Variable valve timing (Vanos, VVTi)
✔ RPM & torque limiters
✔ Throttle response & control
✔ Increased rail pressure (fuel pressure)

These adjustments enable optimal power delivery while maintaining high reliability.

Custom Chiptuning Files – Precisely Calibrated

Our tuning files are based on extensive testing and detailed analysis. The process includes several crucial steps:

1. Dyno Testing & Data Logging

To analyze the baseline condition of an engine, we perform tests on the dynamometer (dyno). During this, we measure:

📊 Air-fuel ratio (AFR)
🔥 Ignition timing & knock control
💨 Boost pressure (target/actual values)
🌡 Exhaust gas temperatures (EGT)
📟 Intake air temperatures (IAT)
🛠 Misfires & torque curves
🔧 DPF load status

These values form the basis for precise map optimization.

2. Adjustment of ECU Maps

🔹 Fuel maps – optimizing injection quantities for best performance & efficiency
🔹 Ignition maps – perfect ignition timing for maximum power without knock risk
🔹 Boost pressure maps – increasing boost in turbo engines for more power
🔹 Torque limiters – adjusting or removing restrictions for maximum output

3. Road Testing & Long-Term Evaluation

After dyno testing, extensive road testing is performed to validate the calibration under real driving conditions. During this, we check:

✅ Cold start behavior
✅ Throttle response & acceleration
✅ Part-load efficiency & fuel consumption
✅ Maximum performance under full load
✅ Stability at high speeds
✅ Long-term reliability & DPF status

Our tuning files are often tested over several years to guarantee the highest quality and durability.

Tuning Stages & Hardware Modifications

We offer three main tuning stages tailored to specific hardware upgrades:

Stage	Hardware Modifications	Performance Increase
Stage 1	ECU optimization only (no hardware changes)	+15-35%
Stage 2	Downpipe, sports air filter	+20-50%
Stage 3	Turbo and fuel injector upgrade	+35%+

📌 Additional specialized solutions:

• Transmission control optimization (TCU tuning) for faster gear shifts.
• Emission system modifications (DPF, AdBlue, EGR, Lambda sensor, catalytic converter removal) for off-road & motorsport applications.
• Pop & Bang tuning for an aggressive exhaust sound.
