coolant issue preventing vcm muzzler from working fully

I do not think the muzzler knows or cares about the condition of your cooling system. It is simply presenting a lower temperature signal to the ECU.
As a data point, I have had for many years the original VCMuzzler with the 82 ohm resistor. I have never seen the ECO light come on and have never had to change the resistor.

Muzzling the VCM is one of the most important things to do to your Odyssey. So don’t give up.
Your issues and experiences are bizarre and very unusual. Muzzling the VCM is super easy to do. Are you sure your homemade resistor device is correct and hooked up to the correct temperature sensor? Perhaps you should buy one of the recommended muzzler devices.
