I have been thinking about some data logs I took of some runs on a back street near my house. The first log is were I did a nice linear roll into the throttle ion second gear. The tires hooked decently and I ran it up to about 6500rpm before shifting into third and letting out.
In viewing the FAST data log I noticed the AFRs diverging from the injector duty cycle like < (as suspected). The injector duty cycle went to %86 and the AFRs went to 10.81, which is good. The second run I tried to start in 1st and of course the tires spun and kept spinning pretty much until I shifted into third. This time the AFRs diverge from the injector duty cycle like <; however, the AFRs never went below 11.5. I could see the injector duty cycle was lower than the first pass throughout as well. I am trying to wrap my understanding around how does the computer detect load and adjust for it? How does load affect the AFRs? Thanks
