Rimozione del GPF is a professional ECU calibration that deactivates gasoline particulate-filter logic and related diagnostics to keep drivability stable without the physical filter, only where lawful (motorsport/off-road).

Rimozione GPF / OPF / PPF (filtro antiparticolato benzina disattivato)

Il OPF/PPF Off service by TuningBot disables particulate-filter control strategies and diagnostic monitors directly inside the ECU map,
ensuring OEM-like behavior with correct fueling and exhaust temperature management. Each calibration is engineered, bench-validated and dyno-verified.

da Euro 6c (2018+), many GDI engines adopted a gasoline particulate filter. When it clogs or regenerates too often (short trips, urban cycles), backpressure rises, power drops and limp-mode may appear.
A correct filter-off calibration restores exhaust flow, prevents forced regenerations and eliminates filter-related DTCs.

When is GPF/OPF/PPF removal recommended?

Gasoline particulate filters trap fine soot from direct-injection engines. Frequent short journeys often prevent full regeneration, leading to blockage and error cascades.
In these scenarios, an ECU-level solution for off-road/motorsport setups avoids recurring faults while maintaining smooth drivability.

Benefits of a professional calibration

Removing exhaust restriction helps the engine breathe better, keeps EGT lower under load and reduces turbocharger stress.
Eseguito correttamente execu, OPF/PPF Off improves throttle consistency and can enhance real-world efficiency.

How the calibration is engineered

A proper strategy disables soot-load tracking, regeneration routines and associated monitors while preserving torque model integrity and air/fuel control.
TuningBot adjusts all relevant switches and checksum management so the ECU no longer attempts regens nor stores filter-specific DTCs.
The engine remains predictable with diagnostics unrelated to the filter kept intact.

Sintomi tipici prima del servizio

• Frequent regenerations, rising fuel consumption and oil dilution.
• Limp-mode with DTCs for differential pressure or exhaust temperature sensors.
• High backpressure stressing turbo, exhaust valves and catalysts.

Comportamento previsto dopo la calibrazione

• Funzionamento stabile con logica di rigenerazione e contatori disattivati.
• Riduzione della contropressione allo scarico e EGT ridotto a pieno carico.
• Risposta dell'acceleratore migliorata ed erogazione della coppia più fluida.
