Hello

I have a e90 330d and a e70 x5

Both are 3.0D and Auto

Both are 2007 year model

I had some software loaded years ago on the e90

I used the Kess to read the file and want to flash it to the e70.

Who can give me some tips on flashing it with the kess v2

The best tip is DONT DO it!

For starters check if the ECU are identical with identical software numbers. The compare the two bins inside if they seems to be compatible. Then you can start to fiddle with writing using a sketchy china clone.
