we do this digital mapping for many ecu that have issue we buy a new one and dismantle record it then we can test broken part against it But only if the math works to make a business Once you have the test plan then testing an ecu takes up to 1hr but once we have tested 3 or 4 we know where to look straight away and do not need to do test You have to do this to learn it takes 2 weeks to add a new product
