This article shows how to setup a working live tuning environment for Siemens MS43, but other ECUs may be similar.

Hardware Preparation

For easier desoldering and cleaning, put the whole ECU PCB in the oven for about 20 minutes at 70°C or carefully get the flash chip area up to temp with a hot air gun.

Then grab the flash chip with a set of plairs and heat it up with a hot air gun until the solder starts to melt.

Once you feel that the chip can be removed, lift it up and place it somewhere to cool down. This is no longer needed.

After desoldering the flash chip, carefully remove the old solder with some desoldering wick.
