This is precisely my point. Rest of the world tests, they test actual exhaust emissions, and there are regulations and penalties.
US on the other hand legislated computer DRM "for engines" because its cheaper/faster, anything beyond is a super special case. My favorite is actual tailpipe test commercial trucks must pass in NY - they test opacity of gas aka "is the smoke visible?" :o and look for physical presence of all mandated emission hardware for that model/year/exemption status. All of that theater instead of using proper exhaust gas analyzers.
>Parts and computer test equipment is readily available.
Can you download standalone John Deere service software? or did you mean signing up for their paid SAAS package?
