First of all to the discussion about the flashing and the socket.
We can do it either way
The advandage of the socket is (and that's why some customers prefer it) is that the original chip can be put in by you without do any soldering. But they see the socket if they open the ECU. Ok, but if there is the original chip in, what do they know? They can imagine...yes, but they do not know anything? And for sure they can not proof anything.
We mainly use sockets since we (here in Austria) would need to pay more taxes if the car has more power. The insurance and the taxes are calculated out of the power. So the customer feels saver if he can, in case of an emergency, put in the original chip himselve.
The reflashing is some kind of cleaner (and that's why our US distributers are using that method) since it can eaven not dedected if you open the ECU. The other advantage is that the socket is of course an additional device and can produce errors, especially with key systems. (We do not use them). Key systems are additinal devices put between the chip and the ECU to protect the chip from beeing read by a programmer (to steal the software). At the PLCC system fe. the key is about 30mm high compared to the chip allone is only about 3mm high. You can imagine that the 30mm 'tower' has much more forces to the mainboard than the 3mm high chip (which has nearly zero force compared to the tower) especially in a car where you get nearly all kind of vibrations. This combined with a socked can (not must) cause bad connections and as result an ECU fault. So reflashing is much way safer, since the ECU is like original, and will never cause an error out of the modification
So I would say the method 2 methods
- with sockets, but without keys
- reflashing (and without key or course)
are nearly the same from the reliability point of view. But each way has it's advantage....
