My 2018 Mustang is Ecoboost powered, with 10R80 automatic transmission. And has the 01A optional package, which includes drive modes and paddle shifters.
The car is a non-street, designated race car and competes on the 1/4 Drag Strip only (in a foot brake class).
To date, I've been running the car in Drag Mode, with the shifter in "S" and using the paddle shifters to change gears.
This is my 1st race car with an electronic programmable transmission and your help will be appreciated!

Modifications: Custom dual feed 3x3x4 air intake, NX 11910 Turbocharger, Aftermarket and custom charge pipes, Turbosmart plumb back Bypass Valve and auxiliary Tial BOV, Air to Air intercooler, Auxiliary water to air Intercooler, E85 Port Injection kit with auxiliary controller, 3" turbo to rear axle drag pipe, trunk mounted battery and icebox, Drag radials.
My number 1 challenge is trying to eliminate a .200 delay between 100% throttle pedal and rear axle rotation.
Does anyone know the cause of this 2/10th of a second delay and can it be tuned out?

That will be hard to diagnose since the logger can't pick up data very fast. You'd have to log various parameters to see which one, in particular, is causing the delay. Start with APP, then driver demand torque, wastegate position, map, throttle position, etc. If you log more than 5 or 10, it will slow down the data rate and you won't catch the delay. Make sure all are on the fasted polling rate.
In the meantime, it might help to modify ecm 9687 at 0 rpm OSS so it's not reducing driver demand on the way to WOP. You might also consider increasing ecm 6827 so more boost is available when the blade opens.
Make some pedal map ratio adjustments on 0 OSS row and smooth it out with the few next rows below it. Multiply first row by 1.05 as a start. Also make sure your trans truncation tables are raised, if your not making crazy power then just max those out.
Thanks for the feedback guys!

yes, tip-in logic mostly but few other factors like throttle rate limit, torque rate limit etc
