Ever since I installed my ID850s, I have an odd stumble right at fire up in cool condition, around 130-150ish coolant temp. Cold starts are solid, hot starts are solid. A quick log is attached, but unfortunately, I don't have any logs with my wideband in because it is just a PITA to reproduce. I've tried adding a little bit of fuel to a lot of fuel in the cranking fuel tables (20%), but it didn't help... maybe made it worse? I have pulled a little bit of fuel, roughly 2%, that didn't seem to make any change. I haven't tried to pull a lot of fuel yet, but I figured I would throw something up here to see if anyone has any ideas.
The tune is currently on E85, but it does acts the same on both E85 and gas. Log and tune are attached.
