Bosch KE-Jet question

Hi there. Was wondering if you all could tell me whether KE- Jet uses a warm up regulator like the K jet system.

No it doesn't - that's the main difference between K-Jet and KE-Jet.


Instead of a WUR, KE-Jet uses a small ECU which takes signalling from 1. a coolant temp sensor (a separate one from the one that runs the dash gauge), 2. a throttle position sensor, & 3. the airflow meter position, to output a signal to a electro-hydraulic actuator on the side of the throttle body, which influences the air-fuel mixture depending on engine temp, throttle position and current airflow. Other versions can also include input to the ECU from a single-wire Lambda probe.

Thank you for your help, would you know which coolant sensor is the one used for fuel adjustment? I see one with two wires and one with one wire
