I use load quite often for tuning purposes and always think of it in terms of fuel rate instead of air flow...especially on a turbo diesel. Easiest way to explain it is the fuel rate on the 04.5-07 5.9 is limited to ~132mm3 but the duration table goes to 140mm3. That's 94%, and the highest load I would see on a stock tune was 94%. Change some limiters around and load will go to 100% without changing the duration table. But 50% load is going to (roughly, based on certain limiters) be 70mm3...plenty of variables but that's the gist of it.
I see the '18 working the same way as load will hit 100% at lower rpms but as rpms increase the load will slowly come off of 100% as there are limiters keeping it from going to 100% of fuel table. Either way you know just how hard the motor is working, versus how hard it can work.
Watching load I am quite impressed how long the AISIN will hold gears before down shifting. While towing it will hold gears well above 90% load, vs early downshifting like so many other vehicles to.
Yes the CTS2 will show when active regen is occurring. It alerts you with a small green line on the top of the screen. You can then monitor EGT3 to see how hot the exhaust is when it leavs the DPF. I've read that EGT's above 600°F are when passive regen starts to occur. Active regen pushes them to 950-1050°F most of the time.
