I have a 2014 ATS 2.0 AWD.
I just installed a FLEX fuel sensor. I am waiting for my AFE intake and AFE down pipe. I would like to at least enable the FLEX fuel sensor until my parts are in. This will be the only modifications I do. Do I need an extra credit so the tuner can adjust the FSCM? I would ask him but he is on vacation for the next week. I am just trying to have it all in order so when he comes back he can knock this out for me.
