From what I understand that’s correct. It’s not a current feature. This is all new to me and I just got my SCT tuner in the mail yesterday, ForScan will allow you to adjust it. 50$ cable off Amazon and an hour or so on your computer and you adjust it along with other things too. That’s what I’m planning on. Search Forscan in the forums for lots of info

No I don't believe it does.
Grab a GPS and check it but I think that you will have to use FORScan to correct it.
