What are "ready-made"? Dangerous files for chip tuning

What are “ready-made” products in the world of chip tuning and why are they dangerous?

"Ready-made" is a popular term for universal tuning files that are created without taking into account the individual parameters of a specific vehicle. Such files are sold en masse, often on the Internet, as a cheap alternative to professional chip tuning . Although they tempt with a low price (e.g. 20 euros) and quick upload, their use carries a high risk that can result in serious damage to the engine and other components.

Why are “ready-made” products bad?

1. Lack of personalization: Every engine, even the same model, differs in terms of condition, mileage and use. "Ready-made" ones do not take into account these differences, which often leads to incorrect settings.

2. Ignoring diagnostics: Professional chip tuning starts with full diagnostics that detect potential problems (e.g. worn turbochargers, faulty injectors). The "off-the-shelf" ignores these issues, increasing the risk of failure.

3. Incorrect maps: These files often contain overly aggressive boost pressure, fuel delivery, or ignition timing settings, which can lead to engine overload.

4. Lack of testing and validation: Off-the-shelf products are not tested on a dyno or in real-world conditions, which means their performance is completely unpredictable.

5. Safety Limits: "Prefabs" usually have safety system deactivations in them - this way the power is always high - regardless of the consequences. The consequences can be dire.

Examples of engine damage after uploading a "ready-made"

1. Burnt Pistons: Overly aggressive air/fuel mixture settings can cause combustion knock, leading to burned pistons.

2. Turbocharger damage: Too high boost pressure generated by poorly selected maps overloads the turbocharger, which often ends in its destruction. Accurate calibration should take into account the compressor maps to set the flow and maximum pressure maps within their limits.

3. Sticky injectors: Too much fuel causes excessive work of the injectors, which may stick or be damaged.

4. Clutch and dual mass flywheel damage: The "ready-made" clutch often increases torque dramatically and beyond the clutch's limits, leading to rapid clutch wear.

Why is it worth paying for good diagnostics and chip tuning?

1. Full diagnostics: A professional tuner checks all vehicle systems, from the injection system to the turbo and EGR, to make sure the engine is in proper condition for tuning.

2. Individual approach: Each map is tailored to the specifics of the vehicle, its equipment and the owner's driving style.

3. Dyno testing: Dyno testing allows the tuner to thoroughly check the effects of the modifications, ensuring safety and optimal performance.

4. Long-term reliability: Professional chip tuning, performed within the engine's technical limitations, allows you to enjoy more power without the risk of failure.

Summary

"Ready-made" may seem like a quick and cheap way to increase power, but in reality they often lead to expensive repairs. Professional chip tuning, although more expensive, guarantees safety, reliability and satisfaction with the car's performance. Remember that engine tuning is not only about power - it is also, or rather above all - diagnostics and dynamic logs
