I think It would be interesting to see bias scatter plots from different pedal box setups. This is an AP reversed Pull Pedal box.

A Modified Ford Escort standard pedal box with brake bias added. Very ordinary.

That is very sensible way to look at - thanks for the posts.

The very first post is of a car equiped with ABS. The abs tends to scatter the Bias a bit as it works.
I think a crossover type ABS will interfere less.


Jamie,
Is the V8 Supercar data Dash Calculated bias or I2Pro calculated data?

Interesting stuff, looking at the bias plots for different runs and days. This car generally produces nice plots like above, but when the brakes get quite worn, the scatter increases noticably.

The second plot is a whole session from the same car. Started the run with new pads and new rotors, ended the run with badly warped front rotors, and the car off the track with no front brakes :cry: . It appears the new pad material we tried wasn't compatible with the pad material the rotors were bedded with.
