My understanding is that this dyno was a chassis dyno, so the numbers reported are simply torque and HP at the rear wheel. The software for the dyno allows you to put in a correction factor to "correct" the measured numbers to flywheel numbers. For example, assume a car loses 20% of its power through the drivetrain. If the dyno measures 240 HP at the rear wheels, it would report a flywheel HP of 300 with the 20% correction factor. If you didn't enter anything for the correction factor, it would report 240 HP, but would still say flywheel on the chart. I would think that the software should be smart enough to account for that and not report it as flywheel. I'm sure it just depends on how it is setup. The original poster stated that they were not using the correction (1:1 ratio), so you are supposed to ignore that the chart says flywheel and take them as rear wheel numbers.
