I think its hit or miss with some vehicles. I have a 2012, never had issues with oil consumption or other weird behavior. Never saw a need to disable the VCM.
Be careful with the piles of incorrect information out there. At 100k miles you need a timing belt, you say it was done, but was it done with genuine OEM or Aisin parts? If so you are safe. If not, it will have to be done again in 50k miles for safety. If it's random Noname junk, potentially even 40k miles. As for disabling vcm, only use the VCM Tuner II. Do not use products like SVCM, they use cheap china parts and are known to fail. The VCM tuner II uses automotive grade parts.Am new here but wondering what the general consensus is on disabling VCM? I just bought my second Crosstour -- this one a 2010 AWD EX-L with 102K miles.
Any thoughts and/or opinions on the subject?
Thanks!

Perhaps, but I've never seen any hard proof thats the case with all Crosstours and Accords in the questionable engine generations. The few I have heard of failed smog testing (cats were poisoned), and did have higher than expected consumption, and exhibited very poor mpg. If the car has no signs of any of those, why waste the money on a VCM device.It protects the engine and cats long term.
The facelift crosstours have a newer VCM that's supposed to reduce the effects even more, but the 8th gen Accord and pre facelift Crosstour have the j35z2, which has vcm that goes on specific cylinders only. The point of a vcm tuner ii is to prevent damage so you don't wait to repair bigger problems. There is many vehicles that burn oil because their owners didn't install one. I bought my 2012 Accord coupe with 180k miles, and it had a rear bank cat replaced just before I got it, likely due to vcm. I now have a vcm tuner ii on it, though I get 10-11mpg in driving that my Crosstour does 15-17. Yes that's really poor driving but it's still significantly lower in a smaller and 500lb lighter car, I don't believe the Z2 is that much worse than the Y1 in mpg for no reason, thinking about it now that it might actually have to do with some effect of VCM over all that time. So far I've seen no signs of oil burning in 2500 miles, oil was replaced in that 2500 but still. It seems like it's one of the few that vcm had little to no effect on, unless it's effecting my mpg.Perhaps, but I've never seen any hard proof thats the case with all Crosstours and Accords in the questionable engine generations.

My 2012 Accord coupe, a car weighing over 600lb less, is actually rated for 1mpg city and 1mpg highway less than my 2015 Crosstour. My crosstours rated for 20 and 30, I get exactly that.Definitely worth considering an aftermarket VCM tuner for the 2010-2012 model years.
I sold my unmodified 2010 EX-L (that was purchased new) after ~10 years when it started throwing misfire codes and bought a 2013 EX-L V6.
The 2nd gen 2013-2015 CT model with "Earth Dreams" J35Y1 motor gets better gas mileage especially when traveling long distances. Might have some to do with the 6-speed transmission that also brings more power/torque across a wider range of RPM's in my experience.
Driving out to the woods multiple times each year for the past 15 or so, 2010 CT would use right around half a tank. My 2013 can go out and back and still have somewhere between 1/4-1/8th remaining.
