New Moto Guzzi Door Mats Available Now
Kalifornia was the only state with emissions testing, until others started doing it too.As Kalifornia goes, so goes the other states as well.... eventually.
The federal gov't could mandate it by withholding highway funds from any state that doesn't comply. That is what brought us the national 55 MPH speed limit for all those years.
Not in our lifetimes... And not all States. How many States in flyover country mirror Kalifornia's CARB in any way?
...what could easily happen is that future ECUs won't allow access except through dealer only equipment and software coupled to another technology that won't allow a map other than none certified to be used. It wouldn't be that hard to do and then the costs to get around it would be prohibitive. There is no doubt that this will cause new regulations and a greater effort to prevent user access to the ecu in the future. That isn't a "could" it will happen, not in 20 years, within a few.
Bikes of course have had mapping designed to evade the spirit of regulations for years.Look at a Dyno graph and see the dip at 2500rpm which reduces the noise at the specific point measurements are made. ok if you ride at this engine speed all the time if not it's a fiddle.
That doesn't evade anything, it will run like that all the time and not only during some test. Evasion is circumventing the regulation, not meeting it.
The VW TDIs meet the EPA regulations... In static testing... As required by law...
I'd like to know how you draw the line from an OEM programming its own software to fool EPA emissions testing, to the governments having the OEMs make it harder for INDIVIDUAL CONSUMERS to access the ECU ?
I thought the OEM's were already lobbying congress for a version of this. I.e. you own the car and not the software.
So if the testing is done on a dyno how do they calculate emissions at speed how do they allow for aerodynamics, just calculate it?What about front/rear wheel alignment, mechanical losses from the undriven wheels hubs etc.Oh and who is going to sue for loss, VW owners who have faster more economical cars?
might meet the letter of the law just not the spirit.Similary if the letter of the car laws say it is going to be tested with a set method to acheive set results........VW have complied.My wife had an old Peugeot Diesel that had to pass an emission test once a year, beforehand I filled it with premium added injector cleaner and octane stuff then gave it a bit of a decoke flat out on the motorway.It scraped through, one year on the second attempt the rest of the year it smoked like a Steam Train.I really can't see much difference between me and VW.
Nope, law says a defeat device can't used and they used one. If that weren't true this would never have seen the light of day.VW already admitted to wrong doing, not even a question. Question now is how much liability and how much it will cost and who pays.No question what was done, just who did it and who knew about it.So, who will opt out of the class actions and forgo any compensation since they really like their VW?
What I have been hearing is the emissions exceeded the standard by around 35 times. I would call that drastic. (Note that is the standard, not against how the car performs in testing which may be below the standard.) I'm also assuming the "standard" is what vehicle manufacturers are expected to meet.John Henry
I believe that it is important to keep this in perspective. This isn't a case of a manufacturer ignoring a known engineering defect and causing multiple deaths and injuries. What we have here is merely some very clever, but devious code. Nobody died. Nobody injured. It's strictly about the $$$ generated in sales and profits based upon deliberate consumer (and regulatory) deception.Nobody's VW TDI is accelerating out of control to over 100 mph. Nobody's TDI is getting rammed from behind because of a known defective ignition switch. Not one TDI is spontaniously combusting after a relatively minor accident.This is simply about the Benjamins, nothing more, nothing less.Piech wanted control anyway; now he has it.

Can diesel spontaneously combust? :)
No, and neither can gasoline for that matter. Vapor has to have an ignition source that is above the vapor ignition temperature ...Lannis
As an aside. IIRC back in the 80s some cars had a connection from the inlet manifold direct to the exhaust via a valve that opened at idle (test revs) with the sole aim of adding additional air to the exhaust thus diluting the % if pollutants coming from the tail pipe.
