Also, will it function properly? OBD II vs. OBDI. Is this upgrade nessesary at BPU level? What are the benefits vs. the BCC? I'll appreciate any responses.

Thanks for the help. I believe all MKIV TT's have two O2 sensors, but 97-98 are OBDII. I just wasn't sure if the harness was the same.

Also, how much different are the fuel maps? Is it
worth it on a bpu car or should I stay with the BCC?
