Hi,
I just uploaded new versions of the MIUG3 and 7SM Writer.
If you use one of them, please update.
I implemented a loop counter for the ECU answer 'ResponsePending'
One ECU reached the former maximum value and I stopped the programming.
Now I increased this maximum value and only break if an other error occured.
A tip from me:
If you want to program your ECU, always check if you have the latest software version of the Writer.
