Hi

Ok, first of all, no... I did not had a clue how was done, never worked on one of this before... I know have better idea of what is involved, even though, at the point when this was uploaded, I still don't know exactly how is done...
Anyway, watch the video so the above makes sense...
The issue, this Skoda came to me as a non runner... would crank, but no start... not even attempt...
Follow me on this video to find out what was the problem and how to resolve it.

NOTE: It is actually possible to clone the ecu, but the read OTP needs to be modified when write back...
There is information out there on how to do it and which software to use...
