Every shift in WOT the injector duty cycle drops to 0, anyone seen this or have fix?

i have the same isse
Surprised to see that the truck appears to be in closed loop the entire time its at WOT! (based solely on active STFT's and fluctuating o2 mv)
That its right ^^^
Will have to check if its going in PE, I was focusing on the injector shutting down and did not pay attention to that.
make a status bit for WOT and PE,
for trucks usually have to lower the PE throttle mapping to enter PE i think stock its set to 87, bring down to like 50

if you are going to max out the Peak engine torque and still use torque for PE enable it will never go into PE since you will never reach that torque level
x2 if you max out peak you will never go into power enrichment,,,, your having issues when it shifts you havent got rid of the delay where timing drops?

^^^Timing don't drop no more, just the injector duty cycle drops on shifts.
I was not going to max out the the max torque peak but i did just see if the inj duty cycle will go away.

are you going into power enrichment ? how are the o2 sensors when you shift ??

just took a look at your tune and log you have your peak maxed out and you are not going into pe which means your not really making any power

inserting the air fuel ratio commanded hi res in the table display will let me know if i enter in power enrichment?

look at your O2 sensors when regular driving o2 sensors should be bouncing once you floor it o2 sensors should go up without bouncing and should go back to bouncing when you let go actually it goes to O cuz its a 2014

Made some changes on the file, Now the ruck goes on PE and feels way better.
I change back to stock the maximum peak and got PE at WOT.
What makes it not get PE when maxing the maximum peak torque?
There is A LOT that needs to be fixed in that tune.

What else I need to fix?
I'm learning and will like to know.
This truck it's just a stock with a muffler.
I'm not asking for a tune for this truck that's why I bought hptuners to learn, but will like to know what you see wrong here so I can fix it and have something right.
