To address the later points (regulatory certification, ECU compatibility, etc), I think the point here is that they're designing kits to target specific popular models so that much of the work only needs to be done once per model.
Once you have designed a set of compatible, tested parts, doing the conversion on a lot of similar vehicles becomes faster and cheaper compared to developing a bespoke solution each time.
Not sure if they actually replace the ECU or just fake the missing inputs to keep the existing one happy. Either way, I'm sure they retain existing wiring and keep all the dashboard gauges working.

I wasn't talking about type approval. In most EU countries (at least Germany and the Netherlands that I'm sure of) you need to pass through technical inspection if you modify a car. Especially if you change the fuel type or change the power output of the vehicle. > I'm sure they retain existing wiring and keep all the dashboard gauges working. Most gauges are no longer applicable (coolant temp, oil pressure, fuel level) or display the wrong range (the tachometer for instance).
- Reason077 7y agoIn EV conversions I've seen, the fuel gauge is typically repurposed to display battery state of charge, and the tachometer to display power output/regeneration. In modern cars these gauges are all controlled electronically, so it's not so difficult to make them display whatever you like by sending them different signals.
