Need help for sync cam 1krfe

Hello everyone, I am looking for help to configure my cam sensor.
I can start and drive on the primary trigger, the scope is good, but I can’t configure it to start with the cam…

The car is a c1, 1krfe engine, the cam sensor has 3 teeth, 1 per cylinder, it passes in front of the sensor about 50 degrees before the tdc in the exhaust phase.
Primary trigger 36-2.
Thank you in advance for your help
here is the scope and my settings
