Re: 2008 Honda Accord EX-L V6 HOW TO TURN OFF VCM?
Better late than never, and in spite of the censor above:
VCM can be disabled by causing a bad sensor fault in the engine computer.
This can be accomplished by disconnecting the rocker-arm-pressure-sensor connector on the drivers side of the rear cylinder head.
The check engine light will come on but otherwise normal operation. There will be a slight jerk on each drive cycle as the engine reaches operating temp and tries to engage vcm. Mileage will drop slightly.
Your engine mounts and transmission will be less likely to break.
Plug fouling, misfire, oil consumption, and especially the annoying vibration may all improve.
This from experience with 2008 Odyssey touring.
FYI

The Pilot owners figured that inserting an 80 ohm resistor between the Bank 1 engine case temperature sensor and the ECU turns the VCM off w/o tripping the CEL. Google "vcm muzzler" and you'll find the guy who did it. This is for V6. Now, knowing that, I am interested to find out how to do the same thing on the 4 cyl and disable the cylinder disable when the vehicle is stopped, which is driving me nuts even before I bought a 4 cyl Honda.
