updating istep level will it overwrite remap?

Hi all,

I have a bmw f20 118d with 143hp, but has been remapped by a pro and has now 210hp. I do have the 8 automatic gearbox with sport mode and so on. I also have the sport+ coded aswell.

My question is now, if I update me istep levels with esys, will I then screw my remap?
Because as I remember the guy, who tuned my car, took out the module in the hood and put some wiring to it, to remap it. And I don't want to do the istep level upgrade, if I risk to delte my remap.

The reason why I would like to remap, is thatI can't get launch control to work. I have coded 2TB and also the LC to be active, but still I capn't get it to show launch control race flag.
