The Wall Street Journal June 14 2017 , Business and Finance, bottom left of page one " Emissions study hits Fiat Chrysler "

The article goes on to say the same university that uncovered VW found issues with Fiat / Chrysler 2014 / 2015 trucks / Jeep diesels are emitting 25 X nitrogen oxide in real world tests. The university report stops short of saying there were defeat devices / software in use.

The automaker disputes the university testing saying it was done at 50 % higher average speeds and 600 to 700 LB more payload.

So here is a question. If the system looks at throttle position / aggressiveness of application / road speed profile then decides the truck isn't under test then alters long term tuning like an electronic shift transmission learns driver style, would this more complicated work around still be a cheat akin to VW's low tech "Is the steering wheel being turned" trick?

And. . . already priming the mess. . . In May 2017 the US justice dept accused Fiat Chrysler of using defeat SW on 104,000 2014 to 16 trucks and Jeep Grand Cherokee. With such a low volume and Jeep being in the mix, this has to be the small diesel and not the full size truck engine.

Don't take Fiat's pathetic excuse as "fact". If they cheated (and that's still an if, even tho the engine has already been pulled from the market) CARB will teach F.C.A. to bend over and spell RUN.

The VW software was looking at steering angle, not throttle position, to determine that the car was strapped to a rolling road. Aggressive throttle on a Diesel is always going to reduce the level of EGR and increase NOx. For this reason alone, I suspect all Diesels produce immensely more NOx in real world use than on the test bed. I really enjoy these cars, but they are serious polluters.
