The below is from the VCMuzzler II data info. It can be purchased on Ebay for about $100.00 including shipping.

Variable Cylinder Management (VCM) is a technology introduced by Honda on its V6 engines to improve EPA fuel efficiency numbers. It involves using the PCM to shut down cylinders at cruising conditions. During VCM, the valves to deactivated cylinders are disabled, along with the spark and fuel supply. This improves fuel efficiency slightly, however, there are other side effects that many have discovered, including Honda themselves. These include:

Vibrations in the drivetrain due to unbalanced engine operation
Oil bypassing
Excess oil consumption
Plug fouling
Misfiring
Engine damage
Worn out engine mounts

All of these issues are well documented owner complaints, which have led to a class action lawsuit that Honda has lost. Honda has issued warranty extensions covering damage caused by VCM operation for some model years. In addition, Honda has also issued a TSB for fixing those that are experiencing vibration issues.Unfortunately their fixes rarely fix or get rid of all the problems.

Why not do something about it before these issues occur? Stop the annoying VCM vibrations. Prevent long term damage to your engine, aggravating warranty claims, costly repairs, fights with dealerships and vehicle down time.

The VCMuzzler II is a simple device that can be installed and removed in minutes without cutting into the OEM harness at all. Simply plug and go. The VCMuzzlerII works in conjunction with your Engine Coolant Temperature sensor to keep the engine control module from activating VCM mode. When installed and configured correctly, the VCMuzzler II will not cause any Check Engine Light codes to be shown or stored. All of your cylinders will be firing ALL of the time with only a loss of about 1 MPG of fuel economy. Enjoy increased responsiveness and smoother power transitions that you weren't even aware you were missing, no VCM vibrations, no hesitations to and from VCM mode, and peace of mind, knowing that the likelihood of experiencing the above issues is greatly reduced.



The VCMuzzler II comes with the following:

• VCM harness that plugs inline with OEM wiring harness, no splices or modifications to OEM equipment necessary. Easily reversible to stock. All connections are fully sealed automotive connectors.
• Five different resistor connectors to account for variations in vehicle cooling systems, and warmer and colder climates. Changing the configuration is as simple as plugging and unplugging a connector.
• Color illustrated installation / operation manual

The VCMuzzler II works on the following models. Note that not all trim levels of certain models offer VCM. Note also that the VCMuzzler II may work on models other than those listed, but has not been tested. If you are uncertain if your year, model, and trim level could benefit from this device, please ask.

If I had any symptoms like stated above on my TLX I would invest in a VCMuzzlerII. The Honda/Acura dealerships are limited in what repairs they can perform on your car. Often you must go outside the dealership to fix specific issues with your car.

CrashMaster is this your quote or from VCMuzzler: "If I had any symptoms like stated above on my TLX I would invest in a VCMuzzlerII. The Honda/Acura dealerships are limited in what repairs they can perform on your car. Often you must go outside the dealership to fix specific issues with your car. "

Yes, the first and last paragraph in my post are my words. I've heard good things about VCMuzzler (and there are other third party companies who make the same type of product). Heck, I've even heard of some people who are good with electronics who made their own Muzzler, but what I like about the VCMuzzler is that it requires no cutting to the OEM wiring harness and can be removed quickly should you need to take your car in for service.


We all know how dealerships like to blame the owner for making modifications to the vehicle for virtually any problem the car has, so to me, a product that uses the same type of factory plugs where installing and uninstalling is quick and simple is a big plus.


I'll probably eventually get one of these Muzzlers.


But like you, my TLX does not exhibit any of the symptoms, yet.
