TVA Removal (Throttle Valve Actuator Disable)

TVA removal is a professional ECU calibration service that disables the control and diagnostic routines of the Throttle Valve Actuator (TVA).
In petrol engines the throttle flap meters fresh air to set torque and power; in modern diesels it mainly supports EGR operation and smooth shutdown. Over time, actuators can stick or fail and trigger persistent DTCs (e.g., P2100–P2119), causing idle instability, reduced power or limp mode.
This service safely deactivates TVA logic in software while preserving all other ECU safety and drivability functions. For off-road/motorsport use or where local laws permit.

How TVA removal works

We disable throttle-flap control and feedback monitoring inside the ECU so the actuator can be unplugged or mechanically removed without warning lights or limp mode.
Todos TVA off As soluções são validado em bancada e testado em dinamômetro to maintain OEM-level drivability, proper boost control and exhaust management.
Idle control, injection timing and turbo protection strategies remain fully functional.

When TVA removal is recommended

• Mechanical or electrical failure of the throttle actuator (sticking flap, damaged linkage, motor error).
• Recurrent DTCs such as P2100, P2101, P2111, P2112, P2119 leading to limp mode.
• Racing/off-road builds or after EGR/DPF delete where TVA no longer provides benefits.
• To remove an intake restriction and restore consistent airflow and throttle response.
