I didn't see a lot about VCMTuner II so I thought I'd start a new thread.
I only recently learned about the issues with VCM reading threads on OdyClub, and even though my '07 Touring with 130K miles doesn't have symptoms (high oil consumption, fouled plugs, etc.) I decided to disable it as a preventative measure. Since my wife primarily drives the Odyssey, I was attracted to a solution that didn't need to be manually readjusted periodically based on season (she probably wouldn't notice if the ECO light started coming back on).
I saw a thread about S-VCM which looked like a good solution because it didn't need to be manually adjusted, and displayed the correct temperature on the gauge if the actual temperature was too high. I asked about people's experience with S-VCM, which was positive, but John Clark also turned me on to the VCMTuner II which is similar S-VCM, but with added features. There is an accelerometer which will automatically override suppression when the vehicle is at idle, is at operating temperature, and sits for more than 2 minutes for diagnostic procedures. You can activate an Audible engine coolant alarm when the actual temperature exceeds 212F. If you want, you could also install a toggle switch in the cabin to manually enable / disable VCM. There is also a connection for a future optional add-on engine coolant level alarm.
In the end I decided to get the VCMTuner II as the S-VCM was out of stock, when shipping charges were considered, the VCMTuner II was less than $20 more expensive and the added functionality was worth it to me. With the cheapest shipping option (First Class USPS mail), I received it in only 4 days (ordered on Thursday, arrived on Monday).
Today I installed it. It was probably slightly more involved than S-VCM (there is a box which mounts over a battery hold down bracket post with a wing nut provided) but was easy and straight forward none the less. Since installing it, I haven't driven it a lot, but enough to know VCM is suppressed (no ECO light) and there were no codes generated.
I'm planning on keeping it in the standard configuration for a few days, but will probably go ahead and activate the engine coolant alarm feature over the weekend. I'll post updates as I get more experience with it.
