I bought American high performance car magazines with articles on chip reprogramming decades ago.
Any car anywhere receives a type approval.
It took the EPA 6 years to figure it out ?
Where did those guys have their head stuck in all that time, I wonder ?
Half the tv commercials are cheating, deceiving, and flat-out dishonest.
I must assume you're outraged each and every day.
Ignorant me, I assumed periodic vehicle inspection (MOT in the UK) was fool-proof.
rayma - in the larger arc of this as yet unfinished story, it's not the dealers who are to blame
when the corporate net capitalized value plummets far enough, perhaps Mr Musk might be looking for another project 😉

It wasn't the issue of trust that made me walk out. It was the young arrogant
salesmen's tone. I knew if I didn't leave when I left, I would be in jail for adjusting the salesman's mouth.

Certainly (I hope), but US dealers are in general mediocre at best, and thieves at worst. An example:
a Toyota inside door handle, quoted at $180 to be replaced by the dealer, but $5 for me to buy it
on Amazon (and 5 minutes to install it myself).

Turbochargers allow for more efficient engines and better fuel mileage by (1) improving volumetric efficiency, (2) providing less frictional losses compared to larger non-turbocharged engines of the same HP/Torque rating, (3) reducing the weight of the engine over the larger equivalent engine.
Yes, turbochargers do provide for better efficiency and lower emission than their larger counterparts when driven by humans.
I for one am glad to see the emission restrictions as I grew up in California in the 1960s and witnessed the smog laden LA basin on several occasions.

You should come over for a visit.
A number of years ago, a large car company here was fined millions for importing used Mercedes company cars on a large scale size, giving them a brush-up, and selling them as next to new 'demo' cars.
In reality they had at least 60k miles.
(trucks, automobiles, new/used, also in Qatar, even have a yacht broker division)

Something resembling that by a major auto company happened here some years ago, if I recall.
Too bad the clever software engineering required to almost cheat that test couldn't have been put to work in the engine management to actually achieve the combination of performance and low pollution levels proclaimed. If it sounds too good to be true, it probably is
Sad part is that instead of using it as a Band-Aid until they could redesign the engine to meet both the emission and performance requirements, they just left the Band-Aid in place and ignored the problem. If they had spent four years redesigning the engine and introduced it as an upgrade, they would have gotten away with it.
Well lawyers probably already asked what real emisions also went down because of this software...

it's not a miracle how to detect the dyno. Almost every modern car has ABS or ESP installed. If two wheels are turning and two others don't you can be sure that the car is in a test-lab. More common is to test the gyro-sensor. This sensor can detect, if the car is standing, driving on flat or ascending / descending. This is normally used to optimize the fuel consumption if your going uphill, downhill or on even ground. But if the car is standing but the engine is not running on idle revolutions, the software will switch to the "cheating-mode". It's an open secret, that all car-manufacturer are using this kind of trick for more than ten years. I'm pretty sure Volkswagen won't be the last one that is catched up.
I would guess the ECU looks for a steady 3000RPM and makes the fuel/air mixture weaker to reduce emissions.
I used to do consultancy work for a car enhancement workshop where they modified engine maps etc.
We did electronic ignition systems with their own maps.
I also worked on a motorbike replacing its ECU with our own. You could then remap ignition and change the rev limiter rpm.

Something like a Power Commander?

Something like that.
I used a PIC micro to read the crankshaft sensor input.
Then drove the ignition coils from high voltage mosfets.
There was a serial link to a pc that had a program for inputting ignition maps and rev limiter setting.
There were 4 coils on the Honda 650.
It worked on a wasted spark system.
