do some research on the ecu repair people, and make sure you mark your ecu in multiple places to identify it as yours discreetly.
I recall a few people sending out ecu's to a repair place with a "reasonable" check fee only to be told the ecu is irreparable and the company either charging crazy fees to send it back only to send a different ecu or refusing to send it back altogether.
