No disrespect to the original poster here, just sharing my experiences. I initially went with the DIY method and it worked well for some time, but over time and the seasons, I had to be careful with my Odyssey to keep it out of ECO mode. I personally think that it is better to spend the additional money and the VCM Tuner II. I installed it in May 2020 and my Odyssey has not gone into ECO mode since then.I’m about to copy your method. Was the 1/4W resistor enough? Or would you recommend going with 1/2W or higher? Only asking because I already have 1/4W resistors.
