Pre LCI E92, retrofitting M4 seats

[Bmwdoubles_]

Hey guys need some insight info from those who might know. I have the pre LCI M3 and according to the guy on Stone Automotive who did his retro states that those of us who have the pre LCI need to be aware it’s going to lose some functions. He goes on to mention that heating and memory will be lost unless you pull the heating module and some other module from LCI seats.

Can anyone confirm that positioning controls won’t be lost? Or do you lose all electronic functions of the seat until those LCI seats modules are swapped? Also does the button to push the seat forward still work when letting rear seat passengers in?

I probably could live without the heat and memory for a bit.
