Reading the graph of the chassis dynamometer pull is not difficult. Typical chassis dyno (rolling road) graph is arranged like this: the horizontal axis shows the engine speed (or alternatively – car speed) and the vertical (or two vertical, mainly on the left and right side of the graph) power, torque and optionally other logged parameters (eg. turbo pressure, lambda, AFR, exhaust gas temperature or the rate of smoking, OBD logs etc/).
