Problem: I did read few edc17 ecu no issue with Launch X-prog3 programmer but now it’s 3 ecu edc16 I just can’t connect it on bench.
You need Launch MCU3 adapter.
If don’t have mcu3 adapter so probe in pin b12 for kline has no cumminicaiton.
Go ahead because on most of the jobs you need including all key lost for some of the cars,Mercedes all key lost for example and so many other things.
Launch does good job on virgining or cloning ECUs.
