Remember: AFV is simply an adjustment the ECM does. AFV sticking and staying exactly at 100 would be a rare anomaly (and not normal). Yes, it is an important clue when things go awry, but the fact it's adjusting is a good sign.


119 is a bit outside of what I'd like to see (it's adding 19% more fuel). The factory limits of that adjustment are 70-140 from what I see on most OE programs so you're well within that range.


This is the important difference between a open loop tune (non adjusting 'carburetor') and closed loop (the Fuel injection ECM sees what the engine is doing and +/- accordingly several times a second). OL is totally OK for a closed circuit where dramatic throttle changes are the norm and split seconds matter, but for the rest of us, a CL tune allows the ECM to give the engine what it needs to run the most efficiently it can in all situations.
