well the ecu is protected so he said he needs to take it out and open it up and solder something, he also said he needs to take it a drive and log it then change it then log it then change it etc
No soldering should be needed, it's out taken so they can flash it in boot mode (mine was done like this). I'd be a bit worried if he was opening it up to map it

Also make sure he has the right size security bolts to replace it, don't want the dealer seeing that it has been removed
