hey I was wondering if you knew this or not. I got a gsr swap in my ek and I have the skunk 2 ecu in it but I do not pass smog at idle because of it. So I was wondering if you or someone else could tell me, if I can run the obd 2 gsr ecu or should I put in an obd 2 D16y ecu? will it make a difference on the smog machine?

thanks for any help.
