The best, easiest and most probably is to use BDM.
In the event of any failure you have the full content of the ecu.

Indeed just bdm it. But don't look for a cheap tune on this type of car

Many people doing Chiptuning with credit base 180$ to 200$, The main this is to read/write ECU. Few people selling their own cable with tune like 700$ to 1000$.

To read and write this ecu, You do not need tool for 1,000$.
You can do BDM100 or xprog-m clone which you can buy up to 100$.
The other thing is to rework such a file.
You will not settle this with trial and error. If it is to be well done, you must do it with someone who knows it well.
