i understand what your saying, i no that when you unpack the data.acd it gives you a "data" folder to open. so i have just been through the process from scratch. this is what i have done:
1.unpacked the data.acd
2. taken the "electronics.ini" and put that into a folder called "data_override" which is situated in the "extension folder"
3 modified the "electronics.ini" because it has most of the code missing. so i added "slip ratio limit" e.t.c
4 remove the "data" folder so it just leaves the data.acd
5. try on track and notice there are no brakes at all with abs on and the tc is constantly engaged so the car hardly moves.
i am pretty sure i have done eveything correctly.
if i haven't please do let me no i am learning
and thanks for taking the time to explain it. you dont have to but you do
