Certainly the move to frustrate easily replaceable parts by tying it in to the ecu is a dick move.  However, the push should be to challenge that aspect, rather than say ecus should be free to be modified any which way.<p>Imagine airbus or boeing or the FAA allowing uncertified code to enter critical commercial aircraft systems.<p>So, I&#x27;m of two views on this.  Critical systems should not be allowed to be modified by uncertified technicians, or similar, but at the dame time, they should not classify non critical components as critical.  Some reasonable authority should make those calls, not the mfg or Joe&#x2F;Jo public.
