ISTA+ assess the car's current i-step and FA to determine what modules need to be programmed. It then produces a 'plan' to:
1) Program the target ECUs
2) Code the programmed ECUs against the FA, sometimes non-programmed ECU are coded too
3) Import any needed FSC
4) Perform a number of reset and post programming diagnostic checks
what files do i need to update on my ISTA+ to be able to perform the 11/2020 update?

I feel the steering has become too light since upgrading to 07/2020.
4.27.20 is the latest programming data to take you to istep 11/2020.42

Car tech forum has the files (sedoy sticky) but don't think his installer allows Ethernet cable without a configuration change
