I have lost my lifetime license after replacing the hard drive in my laptop (despite cloning the old drive to a new one and keeping the original partition IDs).

Does Multi ECU Scan make any use of Ready-To-Send line in ELM327?

Z czym konkretnie masz problem? Uruchamiasz program na komputerze, na którym chcesz go używać . Klikasz na przycisk REGISTER w lewym dolnym rogu, zaznaczasz i kopiujesz do schowka (Ctrl+C) swój Hardware Key. Następnie wchodzisz na stronę https://www.multiecuscan.net/Register.aspx i wklejasz (Ctrl+V)...

My Punto is also from the first year of production (2006).

I may confirm, that in the same car/engine I also have all corrections of 0.

MES supports only USB and BT interfaces that create a virtual COM port in the system. ELM327 WiFi was meant for iPhone users, as they can't "pair" with non-Apple approved BT devices. Only Forscan (for Ford cars) from what I've seen has a support for ELM327 WiFi on a PC.

The problem is in cable you are using, and not in MES.

I understand you have engine off before executing this (and most of other) test?

It would be great if there was an on-line platform where trusted translators could maintain translations. After reorganization of .DAT files it is now hard to find where new texts appeared. If it would be on-line new texts could be left in english and marked in some other color and/or moved to front...
