Making sure im looking at PE right

[bkg06gto]

Starters car is a 2021 Camaro SS A10
LTH no cats
Rotofab
LT2 intake
E80

The issue im having is how quickly PE is coming in, I've searched through and tried a few things, I have the delays disabled, tq requirement disabled, and lowered the pedal some. What you see on a throttle stab is it commands .88 at the correct pedal input but stays in closed loop 1.0 for maybe a second. then it quickly switches to open loop, fuel dumps to .76 then almost immediately corrects to .88


some things to get out of the way,
no knock, car was dialed in VVE and MAF on 93. I reverified it as well. Stock VVT and related tables. DD tables stock

I'm thinking its related to DD though. during the period of .88 commanded and staying in closed loop 1.0 the immediate axle torque is higher than predicted. As soon as predicted gets above immediate is when the open loop kicks on and the massive fuel dump with correction occurs. My question is does this seem reasonable? a couple of searches through the forum seems to point that DD can determine PE enablement, but I also know getting too crazy with it can make the car about undrivable. just making sure I'm heading the right direction here is all.

thanks as always for any advice

If you change the VVE you change the calculated torque and transient fueling. If the calculated torque is too low or high, it will mess with Power Enrichment unless you modify how that comes in as well. Sounds liek you have too much transient fueling and your torque is off. There will ALWAYS be a rich dip on throttle stab but its usually not that severe.

For your mods, you don't need to touch VVE or driver demand unless you are wanting a more responsive throttle. Since you're on Flex Fuel now, I also suspect you haven't modified the tune to eliminate the torque prediction changes for Ethanol vs 93 octane. This can throw off your car too.

Anyhow, post the tune and a log if you want help.
