what engine mode am i actually

[biholliday]

my o2 sensors are at readiness 400 cats are gutted high rpm enable 4000 / 3900 maf is 15000/300 dtc all o2 related are off 3.7b1.hptdfco is stock ihave a lean spike when dfco occurs and back on throttle my wide band shoots to pegged and not sure how to get rid of it engine spits and sputters too for a second

turned dynamic airflow down to 400/399 got rid of the stumble but now pe doesnt work. also im the only person on this page with 0 responses....with dynamic airflow high rpm enable/disable set at 4000/3900 i can see on wideband lamda when i manually keep it in 4th and full throttle it goes from 96ish to 82ish is when pe kicks in which is correct right? with the setting at 400/399 it stays at 96ish. i also turned off dcfc which got rid of the lean spike when im back on throttle. my problem is im not seeing pe kick in anymore so im scared to go wot thru the gears cuz at 7000 rpm we need the wb to read in the mid 80s right?

I have found these PE settings to work pretty well. When the throttle position table commands PE, it works. I set my throttle position at 30 because that is more than I need for normal driving, and it lets me keep the rest of my lambda just under 1.00 easily since I run open loop. Driver Demand vs torque maximums kept me from entering PE sometimes, just check those to make sure everything lines up, so you are actually requesting more than the ECU thinks it is already giving you. I think the COT was sometimes also making commanded lambda 1.00 and thus not allowing PE to be entered during highway cruising sometimes if I wanted to get on it, but after turning that off, PE is now always entered with my throttle position command.

thank you for responding. so when you are wot your wb reads in the 90s?

No, my PE is set at equivalence ratio 1.16, lambda .86, and that is what the wideband shows when I’m in it.
