I've got the LZO, and it may may not be the same on the big max but I can see the % level going down in real time by monitoring DPF SL % in addition to DPF RG %. Both will be roughly in sync as the % level increases to 100% and a regen is triggered. As you mentioned the DPF RG % doesn't reset until the regen is complete. DPF SL % will decrease while the regen is active. On my truck DPF SL % usually gets down to 6 or 7% when the regen staus goes to inactive. Driving another 4 or 5 miles gets DPF SL % down to 0%.What I don't get is seeing it go down in real time during a Regen. Once the regen turns back to OFF then the "RG %" resets to less than 10.
The distance between regens on the LZO is a shorter distance than on the big max, but they also take less time to complete so the distance I gave may be different on the HD's
