I have a 2015 F Type R with 25K miles. In general it runs great but I have been working through some running rich issues causing the CEL light being set. Recently, I was driving with my scanner attached to look at fuel trims and I noticed the trims changes a lot depending on what "mode" the car is in. Is it normal for long term fuel trims to be in the -15% range when the car is in "DYNAMIC" but -45% when in DYNAMIC and SPORT. I understand that Sport mode adds more fuel for pops and cracks as well as increased throttle response?

This picture is both DYNAMIC AND SPORT turned on.






This picture is DYNAMIC ON with SPORT OFF.
