Hello bimmers my friend just bought an e36 and it has an automatic tranny and is working properly. Yesterday we scanned the code through launch reader and it showed that the ecu from 528 e39 and the engine he has is m52b25. Should he change the ecu to the stock one or keep the one he has. Thanks in advance

If it's not broken, don't fix it.
