The update allows the VCM disengage more often, taking it out of Econ mode.
My advice is to : When on long interstate runs, kick down on the throttle, causing it to run all cylinders. This should help clean the plug and rings.
I dont think the rings will help in the long run. Honda is kicking the can down the road untill they have true fix.
My educated guess is that, due to no combustion in the chamber during full VCM mode, the cylinders become more of a vacuum pump and pulls the oil past the rings and contaminate the plugs.

Thanks for the advise. Luckily, the van is being used mostly for short drives around town in traffic and doesn't stay in ECO mode for very long, but I'll keep what you said in mind when we take trips on the interstate.
