Hello. I am going to try to make this as brief as possible. I am currently trying to dial in my WOT AFR to match my commanded. I set my desired AFR in the PE table and I am using the VE table to make my adjustments to match my commanded AFR. I am self taught and fairly new. I have read every guide, thoroughly studied "The Tuning School" courses, but excuse me as I am still green. As you can see by my attached log I am unable to get a steady AFR across the board. I can not seem to accurately target my commanded AFR of 12.56 and after many, many adjustments I can only seem get my AFR to ballpark in the "12s" with a lot of fluctuation. I feel as though my method of hand tuning numbers in the VE is not allowing for a steady transitions. I will see AFRs as rich as 12.0 and as lean as 12.8 all within the same cell as it rapid fluctuates which makes it very hard to know whether to add or remove fuel. I am logging AFR Error % but I do not feel like multiplying by those large numbers is allowing me to "fine tune". The car runs decent with the fuel "somewhere in the 12s" but I know I am leaving a lot on the table by not being able to get this steady. I am also rather unfamiliar with using the smoothing and interpolate features and not sure if this is causing my rapid fluctuation in AFR. Any guidance would be great to allow me to achieve a more steady, honed in AFR. Thanks !
Side Question: How many decimals are needed to be shown/adjusted on the VE table numbers for proper resolution? I was running whole numbers (125,126,127 etc) and feel like I am not able to get the proper resolution for a given cell. Thanks
Note: Attached are my most recent WOT log file and my current tune.
