You make a good point there, I was talking about more if something goes drastically wrong, your AFR gauge is not going to save you. And, yes generally there is one under the hood however I am running one in my car (electronic, obviously you would not want to run fuel lines in the cabin) and I feel that this is a much better indication IMO. Especially with all the fueling issues our cars have
