But you are metioning that you can connect the cable to take the readings without turning the engine Off.
Most likely I don't know how to use it properly, let alone correctly understanding the readings... LOL

On some year cars, the DME will "go to sleep" if the engine is not running, and the data link will be lost. When testing without the car running, leaving the flashers on will prevent the DME for doing this. But if the car is running, you don't need the flashers.
