Update VCM Muzzler Harness Disable Kit Replacement for Honda 3.5L V6 Engine with VCM,for Acura 2013+, for Pilot 2009+, for Accord 2008+, for Ridgeline 2007+, for Odyssey 2007+

I installed this generic "VCM Muzzler" harness on my 2013 Acura RDX to replaced my failed "intelligent" S-VCM device that had worked fine for 6 years. The connectors are not the best quality but they do work. Just make sure you tug to ensure they are fully seated. I set the dip switch to 82 ohms and verified the resistance with a multimeter (across the black wires). I secured the device with a nylon tie to make sure it wasn't resting on the motor). My test drive confirmed it is operational and the temp gauge needle is 1/2 needle-width below the mid-point on the temp gauge (the same position as the previous S-VCM when it was working). I like that it came with extra resistors, so if the internal resistor fails I can replace it. Out of curiosity I looked up the cost of the one-watt resistors that this device uses. They cost 10 cents. So far, this $9 passive VCM override device replaces my previous active "S-VCM" that cost over $100 and is effectively disabling VCM (and avoiding the attendant issues). If it fails I will follow up.

This unit really works well

Easy to install, and works great! No ECO light.

Felt better throttle response right away. No more hesitation from the vcm. New design is plug and play. I have a 10’ honda ridgeline. Highly recommend.

I see some reviews saying it was bad, I noticed that some come with the red/black wire switched. That is definitely the problem if yours is not working. Either get a replacement or switch it yourself. Mine works great at 86. I still get the occasional eco light to come on but the majority of the time it works and my plugs/oil look a lot better when I look/change them. I’m going to try the other settings and see if I can permanently get the ECO light off. But so far so good. It’s been about a year with it, but no CELs or any issues. Gas mileage goes down a tiny bit but it’s worth it, rather than replacing plugs, oil, or even an engine for that matter. Make sure the wires are assembled correctly, and find your settings because it won’t be the same for everyone. Different car, different climate zones. Very cheap to try out, easy to install. These muzzles shouldn’t even be that expensive like the other ones out there.
