DIE ... SEL
Is this the end will investment/research now switch to petrol hybrids ?
Lock the other one then, I was 'ere first
'Other' thread lockedLock it down man....I dont give a ****
I'm not a diesel kinda guy, so IM'd a few colleagues who are, and they say......
There is (speculation) a clever algorithm that detects when it's on a test cycle (steering angle input, rev range duration, barometric pressure, only driven wheels turning etc). If it thinks it's on an emissions test cycle, it will alter the EGR to give lowest NOx, as well as altering the air:fuel ratio for cleanest burn.
When it's not on a test cycle, the map is optimised for max economy or power, depending on inputs. Not optimised for NOx emissions.
As has been said above previously.

I guess then if you are correct then the investigations will make the same connection. Perhaps they will say they were only following orders(sic).....The engine ECU calibration and code, is done jointly by the supplier and manufacturer.
The usual scenario is that the supplier has their own engineers in the manufacturers offices. They will work together right from prototype up till production, Job 1 +90.
They practically live in each other's pockets, there is no way that they will not have known.
To answer your specific query about the same ECU hardware being used for many cars - yes, the appropriate code will be uploaded to the hardware depending which car it is.
But the code will have been developed jointly, which is why I maintain there is no way in this world the supplier did not know.
