its nitrous woooooooo ha ha ha could be many things my bet is a old imboliser somin like that
Haha, would be a pretty cool idea if it was!

flux capacitor?
Now i really do wish this was true, atleast then i could jump to august then i can insure the bloody thing! haha
I'm guessing the immobiliser might be a good bet, it did come with a key fob but they disconnected the alarm because they couldn't get it started otherwise.. shall have to reconnect it and see!
