Carder may be surprised at the "hullabaloo" now because he released the results 18 months ago, but I have had a hell of a time finding any written documentation of their technique.
Was their research limited to observing the effects on cars as they were driven around (something they did), or were they able to dump and analyze the firmware as well? The EFF wrote a story talking about how the DMCA made it hard for researchers, but didn't actually mention the barriers (if any) in this case.
If anyone has links to the written research or an understanding of how hard it is to get at the firmware controlling these emissions, I'd love to read it.
- molecule 11y agoThe contracting organization, a European non-profit, had wanted to convince European regulators to emulate strict U.S. standards for diesel emissions of nitrous oxides (NOX). So it asked CAFEE engineers to gather data from the field. They rented VW diesels, measured their tailpipe emissions on the road and compared them to measurements on the same cars made in the lab. The discrepancies were huge. http://spectrum.ieee.org/cars-that-think/transportation/advanced-cars/how-professors-caught-vw-cheating http://spectrum.ieee.org/cars-that-think/transportation/adva...
