ECU compatibility betwwen models

Postby dv8 » Sat Apr 12, 2008 6:31 am

my question is:
are all the ecu's of one year the same motherboard just with different rom files.

i see that quiet alot of the subaru part numbers are similar. similar in the first section, mine starts 22611 quiet alot of ecus for subaru start with these numbers. maybe this part of the number discribes the motherboard version and the other numbers that follow are the rom file version. or maybe it just means ecu general.

does the 3.0 , 2.5 and 2.0 turbo and non turbo all have the same motherboard to keep manufacturing costs down and some pins are not used in models that dont require particular functions.
or is it that they are all different in the motherboard design and only have the pins required for that model.

thanks mark 8)
