I still have to tape this thing in place with double sided tape, but it's in and working:
This was just a drive around my suburb.
I could hardly see the red-dot for gforce, so I've made it bigger. I also had the x-axis back to front, so I multiplied it by -1 in the microcontroller firmware - as well as changing FACTOR from 4.5 to 2.25 (each circle is now 0.5G).
I also did a 5.21s 0-100 (the time gets plotted on the speed graph). There was lots of wheel spin though - I need new tyres.
It can stay like this for tonight - I'll clean it all up tomorrow.
(Oh, I forgot - I had to put in a 5 second delay on the gauges thread starting up, these newer units have a power-up spash screen and I was grabbing the wrong graphics surface - so the gauges didn't work at first. Wasn't hard to see from the boot log though, the spash screen was still showing when my gauges setup output came.)
