Immo off Corrado Vr6

[spepdy40]

Hello

I have problems here with a ECU from a VW Corrado VR6.
0 261 203 564/565
021 906 258 CP


after converting to a newer vr6 engine and wiring i noticed, the ECU i get an immo :-( the old one don?t, so i have no transponder and no immobox.

is it possible to immo off this ECU ? cause i cant find any known ic except the EPROM (B 58 157) (BLU4BA40YP)
google says this ic is know as 27c512
can the immo be stored in this one ?

thanks
