Anyone know how oversteer, understeer and wheel locking manifest themselves
in the logged data?

Any help appreciated...

Now for wheel lock, it's easy, you'll see a suddon (sharp) decrease
of speed (normally front tires (eg:yellow & green line)).If the reverse
i guess you made nice spin.

For front lock, you'll have to change FRONT/BACK brake ratio until you
find it satisfying. (I HAVE FOUND that it's almost impossible to prevent
any wheel lock,just by playing with the RATIO,you'll have to change your
braking style,eg:just before it's locks, try to lift the brake before
you finish your brake entry. What i do here is brake full
power,downshift, and then "modulate" braking for the last 10% braking
distance before entering a corner (this is a typical corner).
By the way, you see how you brake with the GRAPH again.

Now for oversteer/understeer on the GRAPH, it's the same principle as
brake lock (in terms of suddon "spike" of speed change). If you have a
gentle under/oversteer it might be impossible to detect on the GRAPH.

One more trick, use full zoom in X axis (X32) and use the MAP icon, this
way you'll see where's your improvment in driving style and setup
changes.

Good luck, Eric

PS: i've managed to do a nice 1m23,558 sec at Silverstone using the full
potential of the graph analyser.
