Bought the car used and this was in it.. it says EMS on it with a dial that can be turned from 0 - 1 -2 - 3 - 4 - 5 - 6 - 7. then back to 1 in a circle... and either direction. the previous owner said it was in there when he got it and only knows it as a 'performance chip'. if you turn it too far one way it kills the car... if you turn it too far the other way it kills the car. This leads me to believe it advanced/retards the spark or fuel.
1. what is it.
2. What does it do
3. how do i tune it in (besides what makes the car 'feel' and 'sound' best)
4. any other info you can give about it would be great!
here are 2 pictures
