Hmm, anyone tried to turn up all the way up and see if volume control crashes? volume stays full up and no volume control from knobs or wheel buttons. Emulator crash maybe? This happens on MOST version of the carsystems emu and with L7 prelci amp.

No flashing solution for prelci L7 amp for the echo issue?

This means your coding is not right . Its safety feature from L7 amp and Emulator is completely not involved. If you coded your NBT to show B&W or anything higher than simple top-hifi , then you get this issue . I faced similar issue specially with Pre-LCI L7 , LCI L7 is basically from E70 or Fxx L7 is basically similar to Individual Amp of E90 , thats why its higher wattage than older big size Pre-LCI L7 .

Try basic coding and if you still have problem contact the vendor directly, for the Most version contact carsystems , for basic version which is small box . Then its not carsystems product .
