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
