Hi guys, I have a Nissan altima 2013 were it has a lot of problems that require TCM/computer replacement. The garage I'm dealing with have tried more than 20 computers with different part numbers although they were gotten from the same car model. Can any body explain for me why this variation is there and how can I figure out what part number could work with my car. Noting that it seems that you can only find 2 similar part numbers between 200 different computers


Thank you

Supposed to use a numbers matching computer, very possible to do damage indiscriminately plugging in other ECMs just because they come in the same car.

The different numbers are for the software and hardware variances every car can have.
