This is a novel and advanced tool for deactivating VCM in Honda and Acura vehicles. Unlike other products (VCMuzzler, VCMTuner, MaxiLink, VCM Suppressor...) it does not rely on a fixed resistor or manually adjusted potentiometer to alter coolant sensor reading.
The S-VCM Controller is an automobile grade, high precision digital tool with automatic logic control. It is programmed to reliably deactivate VCM 100% of the time, while constantly monitoring the actual coolant temperature to ensure it is safe to disable VCM.
The S-VCM Controller is far more superior than the resistor-based tools, because it is Smarter, Safer and Solid.
SMARTER – No need to swap or manually adjust resistors. The S-VCM Controller will always reliably disable VCM in summer and winter, regardless where you live, Florida or Alaska.
The ability to deactivate VCM 100% of the time is a key performance criterion. Every time when VCM switches on/off, the vehicle makes a lot of adjustments such as the ignition timing, throttles position and turns the torque converter lock-up on and off. All these busy mechanical and electronic switching have an impact on the car, and the extra stress on the engine mount is unavoidable regardless how VCM technology improves – all of which are what a VCM deactivation device is supposed to prevent.
Especially when you are driving in frequent stop-and-go traffic, VCM turns on and off more frequently than when driving freely on the highway. But the busy stop-and-go traffic is where resistor tools cannot keep up. Those tools cannot reliably disable VCM when coolant temperature approaches 205F, allowing the VCM/ECO mode to come back when your car needs it disabled most, unless they use a larger resistor, but that will further compromise the engine temperature warning system - see reason below.
The S-VCM Controller does a much better job, because it can keep VCM off in slow and stop-go traffic when VCM/ECO tends to be flashing on/off most frequently. Once installed, it can simply be forgotten. In fact you might completely forget your car has VCM, because there is no need to adjust resistor and you will not see the ECO light even once, unless ... see the safety features.
SAFER – Automatically restores true coolant temperature reading to the onboard computer and on the driver dashboard without tampering with the cooling system, in case your car’s engine overheats.
This unique feature of S-VCM Controller is very important for your car:
If the vehicle engine overheats, you should be able to know immediately. All other products will fool you as if the engine did not overheat, because the resistor is always plugged in there to reduce sensor reading, and the coolant temperature gauge will only show 215F even if the engine has overheated to 270F (when a 82 ohm resistor is added) – see photo 2 for more test data. A resistor product will cause your car computer to always get a false engine temperature, and that will result in it being unable to react properly when the engine overheats. Should this happen, it is dangerous and could harm your car.
SUPERIOR DESIGN AND QUALITY – The design follows automobile grade industry standards, and the component quality meets or exceeds the requirement. It has been fully lab tested in a very wide ambient temperature range of 240F.
The compact design of S-VCM Controller also provides the benefit of very quick and easy installation. It does not need many unnecessary straps and avoids cluttering the engine bay. The package comes with a detailed yet easy-to-follow installation guide (unplug ECT1 harness, plug in S-VCM, and connect power wire).
SOLID BUILD – There is no movable parts such as additional connectors or a removable/adjustable resistor that is more easily subject to damage. The S-VCM Controller is completely sealed from shock, water and corrosion. It cannot be damaged even you soak it in boiling salt water. The solid insulation is rated for temperatures as high as 300F, with extreme resistance to harsh chemicals (brine, acids, bases) and has an indefinite service life. At the same time, it is RoHS compliant.
WARRANTY – It is so solid that the S-VCM Controller is backed with a confident six-month warranty in the very unlikely event it stops to perform as described (excluding damages due to physical abuse). No other similar product offers this for what you pay.
SMARTER AND SAFER TO THE BOTTOM LINE! – When a resistor tool fails while you are driving, your car's engine will be in trouble because the faulty resistor cannot remove itself to let the car's onboard computer get the correct coolant temperature. The S-VCM Controller is different – even if it fails its design ensures that it would quit as if it is not installed.

Making the S-VCM Controller available does not mean to ask or decide for you to disable VCM. You are responsible for the consequences of using any VCM disabling tool.
What is the extra wire for?
It connects to car battery positive (+). The wire has a ring terminal at the end so it can be securely attached to the bolt on the battery post. You do not need to find a switch power source in your vehicle. The device uses no more than 8mA electricity. To your truck, this is negligible. In comparison, it's only a fraction of the power the standby vehicle uses to listen to your remote key at any time.
The heat resistant multi-strand copper core wire exceeds the physical ratings required for Japanese vehicles. The wire will remain flexible in the extreme cold weather of Canada..
Does it function by adding resistance to the coolant sensor?
No. A fixed resistor is insufficient and misleading.
The resistor method is rough, because the resistance needed to prevent VCM is different at for example 200F than 185F. At 200F the resistance of the coolant sensor is about 190 ohm, as compared to 246 ohm at 185F (based on a test sensor). To prevent VCM by keeping temp. reading below 167F, the needed additional resistance would also be different. You could use one size – the bigger resistor – to try to fit all, but it will then be over or under rated when coolant temperature changes.
Adding a fixed resistor is also misleading because a given/fixed resistance means differently at different temperature levels. From 167F to 176F (temperature change = 9 degrees) the sensor resistance is reduced by more than 40 ohm, but from 203F to 212F (temperature change = 9 degrees) coolant sensor resistance only reduces by less than 30 ohm. Lab tests show that at the higher temperature range, Honda coolant sensor is extremely sensitive – a decrease/increase of 66 ohm in resistance equals a whopping increase/decrease of coolant temperature from 240F to 305F – that is a 65 degrees difference!
When a 82 or 120 ohm resistor is added, it significantly distorts the temperature reading the ECU gets (which may not be a problem when engine temperature is normal). But this effect badly falters coolant temperature warning when the engine overheats. An 82 ohm resistor is reducing way more than 15 degrees on your dash and what the ECU gets when the engine is overheating, and with a 120 ohm resistor added on top of the coolant sensor the ECU will never get a reading above 230F even when engine coolant is steaming at 250F, 300F or even 500F, because by definition when the sensor circuit resistance is at 120 ohm, the ECU gets a temp. reading of 230F, and a 120 ohm resistor makes it impossible to go below that resistance. The result is that on the dash, you will never know even when the engine is already red hot. That is very dangerous and should absolutely be avoided (someone may think the chance of engine overheating is low, but I don’t want to take the chance). The temperature gauge is on the dash for a reason, and there are common causes for the engine to overheat – coolant level too low, radiator fan stopped working, overload while towing uphill … It’s there for you to keep an eye on the engine temperature, so don’t let go of it for deactivating VCM.
Will ECO/VCM occasionally come back?
This is typical of resistor based tools. The reason, as some explained, is that when the engine heats up in stop and go traffic, the coolant temps climb a bit, then VCM may activate. Occasionally creeping above 167F in heavy traffic is expected with resistor based tools, especially on hot days. There are also mentions that climate can play a role and how this may affect the choice of resistors. One product uses a potentiometer to try to accommodate a wide variation in seasonal temperatures.
In S-VCM Controller, the intelligent signal moderation is different and automatically adapts to driving conditions. You can count on it to continuously disable VCM in crawling traffic even on hot days.
How does the S-VCM Controller work?
It monitors coolant temperature on ECT#1, and feeds a compensated signal to ECU (higher temperatures yield lower signal readings). The compensation is not a constant, because on one hand it should be sufficient to keep the reading below 167F (so VCM does not activate) while the actual coolant temperature fluctuates in driving (the coolant sensor’s resistance changes as well); and on the other hand, it should allow the gauge on your dash to reflect temperature fluctuations between 120F - 210F while you are driving.
Most importantly, the compensation is cancelled when S-VCM Controller detects engine overheating, so you can see it on the dash and the ECU can do whatever necessary in response to the true coolant temperature.
Why does it release control when engine overheats? Wouldn’t ECT #2 deal with overheat situations?
ECT #2 will do its part of the job, but it cannot replace ECT#1 on which the VCM deactivation mechanism is being applied. Tests on Honda/Acura vehicles showed that when ECT#1 temp. reading alone is increased to a certain level, the radiator cooling fan kicks in – regardless of the reading on ECT#2. This means that the ECU also relies on ECT#1 to respond to coolant temperature changes. What else uses ECT#1 reading? Someone that works for Honda and programmed the software logics in their vehicles would know. I would simply let the ECU handle engine overheating in different scenarios.
The S-VCM Controller is designed to be effective and precisely on target. The design concept is to control and minimize the impact on the whole cooling system while delivering the required function, yet interfere with factory settings as little as possible.
Will installing S-VCM Controller cause damage to my car?
No. The principle followed in designing it is to maximize the protection for your car in deactivating VCM.
Is the more sophisticated S-VCM Controller less reliable than resistor-based tools?
Reliability is determined by a number of factors. A modern vehicle has many thousands of electronic and electrical components. That number increased exponentially over time, yet the overall reliability also became higher than the cars decades ago. To reliably perform, the system must work within designed parameters and avoid deviation from normal performance specs. For example, adding non-adaptive resistance to the temp sensing circuit is something to avoid especially when the engine operates at relatively high temperature ranges. The S-VCM controller follows the principle of minimal interference introduced into the vehicle and employs a graceful fallout mechanism. Its fault tolerance ability is significantly higher than the in-line resistor configuration. By design, the S-VCM is more reliable than resistor-based tools, both during normal temperature engine operation and in dealing with extreme situations.
Another important factor is build quality (which also varies between the 4 or 5 resistor-based tools found in the market). In S-VCM, only solid state components are used; moving or removable parts are completely avoided. The service life of the used materials is indefinite. The physical and electrical ratings, such as temperature and voltage, are scientifically calculated and adequately met (the heat resistant wire is rated for 3000 V and will remain flexible in the extreme cold weather of Canada).
The S-VCM Contoller is as reliable as the PCM electronics in your vehicle.
Is the S-VCM Controller a pilot model?
The product you receive is a stable version of the S-VCM Controller, which has been fully tested to deliver the promised performance.
However, this does not mean there are no other versions (for different and new vehicle models) or it will not be modified in future. All electronic products evolve over time, and the S-VCM is no exception. Satisfied users continue to provide feedback and suggestions for additional features and improvements. All that will help to make the future S-VCM Controller even better.
Is it normal that a check engine and/or VSA warning appears after installing the S-VCM Controller?
Usually this won't happen, but it could occur in some cases (to VCM deactivation tools of any sort, because they all modify coolant temperature sensor readings). You can either clear the code if you are sure that is the only cause and know how, or simply drive a few days and the warning should disappear.
Do I need to remove S-VCM before doing an idle relearn?
No, there is no need to remove it. Just disconnect its power wire, and you can do the idle relearn while leaving the controller in place.
Why is the eBay listing price higher and sometimes run out of stock?
The 'svcmcontroller.com' website has a different selling cost base than the eBay marketplace. It is a secure website initially created for garages to order directly, and maintains higher stock availability. It also allows you to specify the vehicle (model, year) and add a note to your order at the same time. You can choose to buy on either platform. The service standards are the same, although free shipping can only be applied to (repeat) orders placed on the website.
Can you ship expedited?
Yes, this is possible upon request and before the product has been dispatched.
Default shipping to US is via Canada Post or Purolator. Transit time is also affected by US customs processing, besides transportation. International packages to US destinations are collected by Canada Post, then handled by US Postal Services or UPS. eBay does not show tracking via Purolator (the commercial express arm of Canada Post) but you can find transit status on the website: https://www.purolator.com/.
If you need expedited or to use another freight service, please contact immediately following your order. Please note that if you request for expedited shipping, those options are more expensive and the additional cost will be covered by the buyer.
