The car has a Pi system 2 with mini dash and can log rpm, speed, throttle angle,brake pressure, steering angle, g load,
oil and water temps and
oil pressure. I scale it before I go on a level floor. I don't have a portable scale platform. If we change springs we make the mounts similar side to side and then set corner weights again when home. Segments are much more precise on a short course than the Pi and are what it all about point A to point B.
