Rule of thumb is to take it once and it becomes a delta. Hence a run on a Hyperpower that makes 100wkw+20wkw drivetrain loss results in a 120kw flywheel reading. Fit your chip and run again 108wkw+20wkw drivetrail loss from the initial run equals 128kw. Notice the 8wkw gain and 8kw gain.
Doesn't work like that. Drivetrain loss is done on every run. You have to specifically get out the car & uncheck it. It's on by default. And the gains are also wrong. Flywheel gains are higher.
I can print these for every single car, but I'll use one example to prove the point. Here's the same 2 runs for the same car with wheel & flywheel gains:
Gains are 9kw vs 14kw. Which means the flywheel graph is showing a 55% better increase than the wheel graph.
And also the graph it probably looks like the coast-down losses were only done once, but they weren't. All Hyperpower graphs only show the coast down for 1 run on the graph. But they are done on every run by default. Look at the dyno after a run & it says "stop dyno" and waits for the rpm to drop before it shows the power on the screen. That's the coast-down it's doing. It always does it. You have to explicitly turn it off on a per-run basis in order not do it.
Anyway, it's a waste of time arguing about this, I think it's a given that nobody cares about flywheel power.
