I have never heard of that before, I'll have to hunt down that conversation and look into it.Apologies, I'm not articulating correctly. Forget about VCM for a second. Remember all of the discussions about how coasting in neutral used more gas than by letting off the gas and keeping the car in gear? From there it was explained that when you let off the gas (when moving) the injectors turn off and the engagement of the drivetrain keeps the pistons moving, not combustion. The injectors only turn on again right before the car stops to enable an idle. So now back to VCM. When VCM is engaged, the front bank of cylinders by the firewall continue to go up and down with no fuel being injected into the cylinder. What is the difference to the cylinder itself bewteen this and coasting (for all cylinders)? The way I see it, nothing. But this would have been the case with the last gen Pilot (with all its VCM issues) as well so my point is there's more going on that's engineering related and way above my paygrade. It's just like carbon and DI. I don't think the DI 2.4's which have been around now since 2013 have carbon issues so once again there some slick engineering going on.
