if I understand the situation correctly, Bosch supply the ECU, programmed to what the customer wants, ie to the a set of specific 'profiles' that the customer has given them. Whilst it's normal to program how the motor should respond according to a set of parameters like speed, steering, throttle variation and desired mpg, the matter of priority between conflicting variables like mpg, responsiveness and emission gases is decided by the client. The cheat is in one of the profiles happens to be close to one that is used in tests. So, who is to blame? the VW guy who specifies the driving profiles because the 'test' profile is also a realistic one? the Bosch software engineer? I suggest to you that the real culprit is the agency that designed the test conditions that make an ideal engine possible.

It has shaken up the US testing body which is "revising our methods". When there is a test situation companies and individuals alike will do what they can to get the best score. The whole "real world" emissions testing thing is as far from "real world" as it could be.

 

Anonymous testers hiring cars with a certain mileage on already and running them through emission tests would be closer to real world.

Do people actually specify what ECU map they want and then it's programmed for them before they received their car?

 

I always remap my turbo charged cars. Not from a boy racers point of view but the experiences I have had from doing this have been favourable. Both in fuel economy and performance

Nope VW does generic mapping. Smart people like you go an make it even better.

Maybe they have ambitions to gas the entire population of the planet this time.
