Typo in index.html.

Line 284.

rpmmeter.style.dispaly = 'none';

Change to:

rpmmeter.style.display = 'none';

I found sometimes the markers on RPM and Gears would tighten up and appear together in a small circle in the centre of the meter, instead of being spread out correctly.

This seems to have fixed it.
