Hi, I've had this problem when I first had my car up running. Its not rev-limiting because your rev limit mode is set to fuel cut and your injector duty cycle is going over 100% which prevents the rev-limit from working. You should set your rev-limit mode to ignition cut. Is the onboard lambda sensor installed on the car? In the logs the lambda trace is pretty lean around 5000rpm and super rich up top which is why the injector duty cycle is going over 100% -Cameron
