Today I meet this kid who had this nice ass turboed integra. He pulls the key out, walks away and then about a minute later, the car turned off. So I asked why and he said it was his Turbo timer (Never really knew what they did) He said that all hondas should have them because of the fact it helps cool the oil down (said something like that) just like the turbo timer gave time for the turbo to cool. Also, the apex-i T-T has an air/fuel ratio meter (however, he said that the accuracy is only good if you buy a wide band O2 sensor) as well as O2 sensor voltage and Battery Voltage. Plus the other good thing, it is only a hundred or so dollars plus it is not a big old gauge. So the question is, should I pick one up? Is it totally unessacry with NA cars?
