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

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.

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 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 VCMuzzler works in conjunction with your Engine Coolant Temperature sensor to keep the engine control module from activating VCM mode. When installed correctly, the VCMuzzler will not cause any Check Engine Light codes to be shown or stored for your dealer to see. All of your cylinders will be firing all of the time, just like they were designed to. You have full V6 power all of the time, with only a loss of about 1 MPG of fuel economy. Enjoy increased driveability, no vibrations, no hesitation and peace of mind, knowing that your likelihood of experiencing the above issues is greatly reduced.

The VCMuzzler works on the following models. Note that not all trim levels of certain models offer VCM. Note also that the VCMuzzler 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.

Sorry to all about the shipping costs. I've now sent out invoices to everyone that purchased one that includes the shipping cost. I thought I had set that up correctly on the listing but still learning as I go.

I should have these sent out by Wednesday at the latest.

I have enough parts to make 100 of them, and that's how many I originally listed on ebay, however because I'm not a verified seller in their books, my listing got taken down and I had to limit it to 10 as that's all they allow me to sell per month on ebay right now. Once I successfully complete these transactions and get positive feedback, I can ask for my limit to be increased but there's no guarantee they will. Might have to wait a month, sell 10 more then reapply for an increase.

Sucks because I know there's lots of interest and I hate making people wait. I can see why they do that on ebay though, I'm sure there are lots of scams out there and this is their way of limiting fraud.

Maybe we need to start a waiting list since only 10 will be available per month

You can just sell it here and eliminate the eBay fees. Just pay through PayPal.
Agree with this. Should allow you to lower the price for us too ;-).

Just do shipping quotes by PM and let us know what your paypal e-mail address is.

By the way, I'll be including installation instructions with each shipment. It's pretty easy, but there will be pictures / diagrams showing how to do this.

I'm going to concentrate on getting these first 10 out as fast as possible so that I get good reviews from everyone. I don't want to fall down on the customer service side.

After that's done, for those that aren't willing to wait for ebay to let me post more, I'll send out instructions for how we can do this through paypal directly.

Thanks everyone for your support and patience so far.

Ok, so by request, here's some pics on the install. Again, I'll provide instructions with the unit, but basically it's this

1. Remove engine cover (super simple)
2. Locate ECT1 sensor on drivers side of engine
3. Get your hand in there, press the flat release tab, remove connector.
4. Plug female connector from harness into male side of VCMuzzler.
5. Plug female connector on VCMuzzler into ECT1 sensor.
6. Re-install engine cover.

Technical question: Are you essentially "spoofing" the ECU into thinking the engine is always running cold?

- Mark
Yes, that's exactly it. The engine is actually running at the same temperature as always because that's controlled by the fans and the thermostat, which seem to be unaffected by this mod. The PCM just thinks the engine has not reached operating temperature yet, so it doesn't activate VCM. Haven't seen any other side effects of this mod after over a month of running it full time.

I agree with this also. I'll do just that, but for now, I just want to get these first 10 orders out before I take more. I'll be ready to take more orders by about Thursday. I'll post details at that time.

Thanks for everyone's patience. I hope there's just as much interest once I post on the Oddy, Accord, RDX and TL boards. :)

I suspect interest is going to far exceed your production capacity.

Have fun!

Thanks for prompt and straightforward answer.

Certainly the thermostat is unaffected, but I would think coolant temperature is used by the ECU and factors into other engine operating characteristics and tuning, possibly even A/F ratio trimming. Be interesting to see some comprehensive long-term data on gas mileage.

I would never consider such a mod as an acceptable way of disabling VCM, but that's just my opinion.
