My wife has a 2013 Honda Accord V6 Touring sedan with VCM. It has 27,000 miles (yes, that is correct). I do not like this technology but this is the car she wanted and we bought it used with 8,500 miles and in excellent, like new condition from a Honda Dealership. I have had the oil and filter serviced at Honda, but it sure seems to get dirty quickly and I wonder if the VCM plays a role in that. While researching online the past few days, I am learning that the VCM causes engine part abnormal wearing and is not good for the long-term life of the car.
So I am hoping to find a solution that deactivates the VCM without causing any of the negative consequences that others have mentioned such as inaccurate engine temperature readings and codes popping up. Something that solves the problem once and for all without creating new problems. I do not understand all of the technical jargon used to describe these vcm deactivation systems, so please respond with beginners terminology, if possible. I have read about vcm tuner II, vcm muzzler and K tuner but I do not know which is best. The first two seem to attach to the wiring bypass the original vcm and connect to the positive terminal of the battery, but seems a bit primitive, while as I understand it, the Ktuner re-programs the car's computer. Any knowledgeable information would be greatly appreciated.
Thank you
Here is a good thread on the topic:
thank you joec for taking the time to search for this thread and post it. Very informative overall regarding vcm, but I am still confused a bit regarding the different de-activation devices and which is best. I suppose I will need to find a local honda mechanic to give more advice and recommendation. Anybody know a good mechanic in Corona, CA?
In order to disable the cylinder deactivation on your car, you going to have to take apart the engine and replace the lifters and camshaft that have been affected by the VCM; as well as retune the ECU.

Thank you for your response. I am hoping that with only 27,000 miles not much damage has occurred to the lifters and camshaft as you mentioned and that retuning the ECU will solve the problem...though I am not sure what retuning the ECU does or how it is done.
You would need a mechanic with a high-end scan tool that has reprogramming tools to get into the ECU.
thank you. I will check around.
There was a class action suit which included your model but that cutoff was in 2014.
Try punching your VIN into the ntsha website & see if there's any recalls you can participate in.
I will look into that. Thanks.
Buy ktuner and have it disabled..
thank you for your advice. Being unfamiliar with these devices, do you know if the ktuner is installed on/in the car or is it a download that changes the car's vcm computer program. Or any other information you can contribute is much appreciated.
It changes your software.. there is the factory setting and a tuned up version. If you just want to disable vcm keep it on factory setting but select the vcm disable tab . It will upload it to your ecu and vcm will never enable again. The rest will remain factory as long as you did like i stated.

Thank your for the information. Wow, that was back in April when I posted this question but have not had it changed because I am new to California and do not know good a independent mechanic here, except for a front end and brake guy. But just recently I met a mechanic when I went to the Honda dealership to purchase an engine oil filter and ATF for my wife's car. And just yesterday I thought that I need to contact him to see if he has ever deactivated the VCM on a 2013 Honda Accord V6. So your response was timely. Thanks again.
