timing

Unread postby lugbolt » Tue Dec 03, 2019 10:30 am

Played with the '92 gt yesterday. Just sitting there idling, on a A9L2 tune with the MAF transfer provided by pro-m (92). I was looking at SAFTOT and it was idling (hot) at 12°. Of course I put that in when I entered FN904A during A9L2 setup, and it was purposely entered as a "safety" margin, since I have no idea what it might want. Well during the log and play session, I decided that it might "like" 20°. I expected to see SAFTOT within a degree of what I commanded, but after updating, it stayed around 12°. I know, noob stuff, but what did I do wrong? Or is the ecu adjusting it for idle purposes? Fuel is nowhere near dialed in so I haven't been able to drive much other than idling to/from the driveway and shop.
