WOT problem on fueling HELP.....

[NOWAY55]

Looking at a recent log file when I first go WOT, it seems to go rich like it should and the actual AFR goes down like the desired. Then about 1/2 second into it, it goes lean for about 1/2 second then goes rich again after another 1/2 - 1 second. This leaning out in the midlle is causing some KR problems. Any ideas here what would cause this?

What does your injector cycle duty percent look like? Could you be maxing the injectors. How about fuel pressure? Any way to monitor that?

Can you post a log and your bin? We might be able to see something in the tune where its causing the afr surge

How old is your fuel filter, what is your voltage at fuel pump, how much gas did you have in the tank, maybe your meth needs to be adjusted or the filter for meth needs to be cleaned.

What is the easiest way to post the log file? Free Space somewhere to load it up?
