Im assuming the red one was her last lap?

I love the G-spot one I like how random so of the dots are! Must of had some serious twitches!

Looks pretty consistent from the first graph, would love to see how shockingly bad mine would be if I did something like that

Don't understand any of the above. But i'd say that would be a pretty boring dot to dot.

top shows 3 laps.... Speed on Y axis, Time on X axis. Speed against Time.

The dips in the graph are corners/deceleration. Peaks will be end of the straights.

The bottom one shows G Force under acceleration, braking and lateral (sideways)

So she was corning with 1.5G, braking with -1.5G... and accelerating consistantly with 0.5G.

No idea if those G's are decent

Adam - I think a Porkie 911 runs up to 0.95g at high speed cornering for comparison.

Race cars produce a lot more though.

Love the data timing.... Shows where you can improve if your get rid of fear

yup... thats the hairpin. On the 'red' lap she was a good second quicker getting there, but looks to have had to lift mid straight.

1.5g cornering! good fun must have some positive cambered corners surely?
maybe it was a missed gear change?
anyhow what bit of kit are you using as i bought some innovate stuff ages ago and yet to fit it!

Where is the G-sensor attached in the car?
It looks like there were a few slower cars on the track getting in the way.

Have you got throttle position, steering angle sensors, these will make things much easier to improve your lap time, I've spend a lot of time doing telemetry and know a lot about interperating the graphs.

just a stand alone Race Logib Performance box (and software from their site)

No addition sensor inputs, just GPS.

I see, where is the box? It should be in the middle of the car on the floor.
