Argh! Here we go again. The idea that if cars with black boxes on them canÕt be worked on is so out of date as to be laughable. If we take the view that the next generation of cars to become ÔclassicÕ are 20 years old, weÕre presented with many, many fitted with engine management. My experience is that cars of this age have ECUs, which any halfcompetent kid with a laptop and a lead can crack into and work on. If weÕre in a situation where an ECU is physically damaged (water etc), most printed circuit boards can be repaired, and their contents be re-uploaded from a saved source. Beyond that, thereÕs always the possibility of building new ECUs from scratch, and we have abundant mini-computers, such as the Raspberry Pi, which can be adapted to suit. Nothing electronically from the 1980s or 1990s canÕt be fixed or rebuilt. And equally, going forwards, I doubt that current technology wonÕt be cracked by enterprising kids and their laptops. IÕm more concerned about interior parts and body panels than electronics.
