Not sure if this car's Maintenance Minder factors in time for the oil life. I don't think it does. The 5th gen Odyssey (2018+) was the first to have this feature and Honda said they would add it to the rest of the lineup with the next refresh.

But yes, it does consider many different factors. Temperature (both ambient and engine), run time, etc.

I have not been removing my vcm tuner for oil changes, and never had a problem. Has anyone ever had the service department comment on it?

I know people have brought it to the dealership (even while under warranty) and they said nothing (either because they didn't notice or didn't care), and in some cases the dealerships have even unofficially said they know about it and endorse it.

If you have a passive device (ex: VCMTuner I, VCMuzzler II, etc.), it's even harder for them to notice compared to active devices with the more obvious wire to the battery.

The only time I took my Accord to the dealership, it was to get keys made, so I'm guessing they never even looked under the hood to begin with.
