Hello, I have to fit used hsfi 2.6 on Zafira z16yng, I reset it and program immo, but p1605 and p1606, still remain active. I want reflash it by tech2, someone can help me with good vmware image or explain me how to do it by official website? Thanks.

install globaltis v32 - that should work.

or search acdelco tds - register an account and buy a subscription. it might not fix your problem though, the used ecu could also have issues

generally, if the ecu has come out of the same car, same year same same same you dont always need a reflash, especially if the software numbers match up.
