I did a test with another used LSU4.2 sensor.. same result. When at idle everything works as normal but direct when i start to drive the car it shuts of cloosed loop..
I starting to think its my software version or something.. The ECU initially used 06A906032HJ 0002 But i flashed another 06A906032HJ Stage 2 version to the ecu.
