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

Works for now

Have installed this on two different vehicle with complete success. 2015 Odyssey and 2015 Pilot. The wire connectors seem good quality with a satisfying click when installed. Installation took minutes with basic tools. Infuriating story on the Odyssey, which belongs to a nephew and his wife. They have three kids. First occurrence of misfires and limp modes occurred while they were on family vacation some 15 hours away. Shop replaced the typical plugs and coil packs and charged a couple thousand dollars. Same symptoms returned some months later. Their local mechanic repeated the same “repair” as previous mechanic along with a couple more thousand dollars down the drain. Some months later, same issue: misfires and limp mode. Then they told me about it. I immediately suggested installing this muzzler. They agreed - why wouldn’t you for such little money? Installed muzzler along with 3 of 6 spark plugs. Two long road trips later, they have had zero repeat issues!

I called Amazon to get clarification from the seller. Others have made the same comment. The small circuit board has a V+ and G solder contact. Black marker was applied to the designated point in an attempt to hide the polarity markings. The red wire usually the power input was connected to the (G) ground point and the black wire usually the ground wire was connected to the (V+) or power input. Other buyers have noted this and suggested switching the wires. There was no response from the seller and i wasted 4 days waiting for a Amazon rep to respond. I finally received s voicemail which i could could not comprehend. Even Google transcript could not decipher. I recommend not puchasing this item unless you want to flip a coin with possibly damaging your car's ECU. I returned the item for a refund.
