Yeah I'm not afraid to admit I made a mistake 5 years ago when I was younger, I have grown up a lot since then for instance I don't drink at all anymore been booze free for 2 years now.

I'm only asking because I had to get one put on my car and this thing is wired into all parts of my harness even my tach. So I'm wondering why would they need to know how fast my engine is spinning.

I'm totally against this thing I mean I can't even eat a donut before I start my car because it will register as alcohol. There's actually a list of food and other things that can give a false reading, and at the bottom of the list it says that the list isn't limited to these items.

Now let's get to the fact that can't do any repair work on my car that involves wiring without their knowledge.

I know I made a mistake but this thing is retarded I mean there's so many flaws with this system that it shouldn't even be a reputable source of info.
