I like to buy a Powergate S without tuningfile for my BMW 123d EDC17.
Is ist possible to read out the Car an remap it where i wanted to,or do i have to remap the file where i buy the Powergate S

I think if the seller set it to Slave i can only make the remap by this Tuner.

Which file format is necessary if i want to write the tuningfile into my car?

Thanks for help
