But looks like you're able to get it matured within 16 minutes, same as my FFV Explorer.
It's interesting how your inferred AFR is 14.00 or lower, but the inferred ethanol % stays 0. Even on my FFV Explorer, the inferred ethanol is about 10% since our fuel is 10% ethanol. Did you copy the Ethanol % AFR table (Table 21320) Should be 9.00 is 100% and 14.64 is 0% - the default table is all 14.64 in the rows with 0 in the column. Just change the first row from 14.64 to 9 and make that cell 100%
I've tried everything but cannot get my 2.7 EcoBoost to mature the AFR, it is stuck in actively learning. I've asked one 2.3 EcoBoost tuner and they only sell ethanol blended tunes and not flex fuel enabled tunes. My 2 theories is that there's some undefined parameter that prevents it from working or it is the design of the wideband primary o2 sensor. The EcoBoost/DI engines use a physically different O2 design from the FFV engines and the Coyote.
