&gt; he was quick to throw accusations around<p>To be fair:<p>a) English isn&#x27;t his native language and both &quot;schummeln&quot; and &quot;betrügen&quot; would be &quot;cheating&quot; in English, though one with much less negative connotation<p>b) in the talk it sounded more like he was saying that the ECU (or other embedded computers) do <i>a lot</i> of filtering and processing already, even in places where you&#x27;d expect to have a straight path from the sensor to the reading (e.g. the idle rpm). When listening to the talk it didn&#x27;t sound to me as he was implying that all of that processing was on the same level as the emissions stuff; just that there&#x27;s a lot going on that most people don&#x27;t even realise.
