So I installed the new O2 sensor yesterday and took it for a short drive. Regrettably it wasn't a magic bullet and the problem remains the same. Not that it is helpful, here is a new data log, the only difference is more time on the tune and the O2 sensor replacement. Next up I am going to revisit MAF scaling, this time with the stock air intake, as last time I was still trying to get the Injen intake to work. Failing that I will try the IAT remapping.
