A little new to this forum and software, but Im having an issue on this 2020 F150 3.5 EB. Did a decent amount of research on here and other forums of what changes most are making to get more power out of their EB, I followed a combination of tune files and others comments to build a tune for my 2020 F150. With 2 goals in mind, More power while towing(modified for above 30% throttle) and more tope end power. Both have been achieved and the truck pulls hard, makes plenty of boost, no engine codes and drives great. The second thing i have been shooting for is to improve fuel economy during normal daily driving and cruising. From my experience this is done by changing the stoich value to lean out the bas AFR( with todays fuel prices, its almost a necessity) which I have done several times. When I did this I also recalculated the WOT lambda values. Stock stoich is 14.08 first i tried 14.5, then 14.8 now 15. Recalculating WOT lambda values each time. I have also in between tried returning to 14.08. but the problem i seem to be having is that the actual A/F has not changed for 1.0 lambda commanded at idle, no matter what i set the stoich at it always reads 14.0-14.3 at idle and while cruising. During WOT the commanded lambda does not match the value i have set in the WOT table under power enrich, i have tried playing with several other setting to get them to match but i am at my wits end and have had no luck locating others with same problem. I have even downloaded other tunes other users have uploaded to compare to that say they are consistently getting their commanded lambda to reach what they desire.
Worth noting...I have and always run 93 octane fuel, I have had other small modifications that i have made along the way but this is the biggest one bothering me, i have no problems where it is and could leave it alone, but the vehicle is not following the values that I inputted, this is the problem for me, I must be missing something
I am uploading my tune as well as a few logs
4p is a 4th gear pull on open road with current tune
12 was same tune but with stoich at 14.8
13 was same tune but with stoich at 14.08
