LT4 Throttle Delay Off Brake

[405mason]

have a lt4/6l90 na setup that is dbw (drive by wire). when launching from 0 flashing the converter there is a half second window where the car doesn't react to the pedal being on the floor. max rotation and throttle area % max vs. rpm are both maxed as well as brake torque management, powerhop, and oil stave are disabled.

0-85 from idle no foot braking as well as the file are attached below.

any points in the right direction are greatly appreciated.

Here is what I experienced with hot rod swaps. If you install a BPS (brake pedal position sensor) you will have this issue. If I floored it the ECU used the torque management will hold the rpms at 1000. I stopped using them since they are not needed. I remove the DTC codes for the BPS. Burn outs will happen after doing this tuning.

The only wire hooked to break pedal is for torque converter lock up even unplugged the bp and still does it

p0572 and p0573 need to be enabled I believe
