HEALTECH STV SECONDARY THROTTLE EMULATOR STVE-13

HEALTECH STV SECONDARY THROTTLE EMULATOR STVE-13

Why remove the secondary butterflies?

The secondary butterfly actuator/servomotor (STVA) often fails and is usually not available as a spare part, but only together with the complete butterfly body (very expensive!).

Why remove the secondary throttle bodies?

The secondary throttle valve actuator/servomotor (STVA) often fails and is usually not available as a spare part, but only together with the complete throttle body (very expensive!). Therefore, it is common to remove the secondary throttle valves to avoid this unnecessary cost.

On some bikes, removing the secondary throttle valves can also increase performance.

Removing the throttle valves and the servomotor will cause the ECU to detect two faults:

- the absence of the STVA actuator/servomotor

- an incorrect signal from the STPS secondary throttle valve position sensor.

The STVE emulator connects to the STVA and STPS pins of the ECU to provide the correct signals and thus avoid the detection of the two faults.
