[Matthew53]

I had never mount ELV emulator but I repaired  many of ELV's with 100% succes and secure. Most problems was ELV motor. Of course repair was more expensive than mounting ELV emulator, but one thing to think about: for most drivers cheap repair is more important than health or life....

That's depend. If everyone around your environment tells you to put the emulator, because it's cheap, safe and comfortable, then you are going to belive. Even when you check opinions, there are no opinions such as mine. So, unaware person is going to put that, because it has no reason to think wrong about the situation.
