I made it to 180k on a Crosstour without the VCM disabled. I had to replace the catalytic converters because I could no longer ignore the P0420/P0430 codes. That bought me another 30k miles or so until the emission codes were back on again. Thats when I found Piloteers.org and learned about VCM disabling. After driving a short period of time with the VCM disabled, the codes were gone and continue to be gone at 264k miles.

Which converters did you use for the replacements?

That stupid "ECO" light coming on in the dash of my 2009 always startled me from day 1 and I dealt with it for 12 years. After reading about the S-VCM here I figured I'd put one in just to disable that annoying feature, this was about a month ago. The Pilot had gone about 210,000 miles without anything happening that I could blame on the VCM.

If you made it to 180K miles on a Crosstour with the original OEM converters, then why did the replacements only work for 30K miles or so?
Good question, got a theory?
This car was going to auction if I couldn't figure out how to fix it. Glad I found this forum for a solution. Decided to stay a while and try to return the favor.

If the VCM-defeat device supposedly tricks the PCM into thinking the engine is running colder than it actually is, then wouldn't that result in a richer fuel mixture always being burned?
Would that, in turn, shorten converter life?

I believe there’s a different ECT sensor that is used for that so it’s not a concern. But to be honest, I’ve always wondered if tricking the car into thinking it’s cooler than it is has any negative impact on other parts.
