can som1 tell me all the differences a turbo timer makes to a car and also when turning off the car, how does it affect its future use?

 

a turbo timer is in line with the power wire to the ingition, basically like a sprinkler timer. When you turn off the car with the key, the car will continue to run until the time limit is up- depending on what you set it at. My room mates will only activate if you tap the brake pedal, just in case you will your car and end up dying 60 seconds later.

No harmful effects, just like stopping your car in traffic for a minute.
