Pedal to floor. TB closes on launch.

[itsdaveonline]

Vehicle is a 2006 ctsv. (1st gen ctsv with slightly older e67). It's a manual.

Long story short you'll see on launch in 1st gear, that my foot has the pedal to the floor the entire time, yet the throttlebody decides to close.

You can also clearly the clutch is slipping. 6500 in 1st should be 48MPH in the log. you'll see in 1st where it goes 22mph at 6500 RPM (tires NOT spinning).

In the tune, all tq management / tcs etc is disabled. Infact the brake pedal pressure sensor to ABS is D/C (vehicle screen says traction control is disabled in car) + disconnected 1x hub in the front.

Why is my stupid throttle closing? What is missed? I do realize the better solution is to clearly fix the clutch. That is happening. But i cannot have the throttle closing on launch. Period.

how old is your software?

have you tried maxing the ETC rate limit in engine torque managment

I'm on 4.4.2. My ETC limit is maxed. But my ETC rate limit is .10. Not sure if 0 or 100 is the value im looking for. But regardless this only seems only tip in / low rpm (up to 4000 rpm?). This is happening at higher rpm.

Here's another example of the throttle body doing weird things and delaying me. How do i stop this2019-11-11 21_57_47-VCM Scanner_ 2006 Cadillac CTS V, 6.0 L, 8 Cyl, 1G6DN57UX60168376 [hit 6 fay.png.

This costed me .1 to .2 on the track. Injectors etc are all just doing nothing even though im on the gas pedal asking for power.

So I adjusted some limiter settings:

accel thresh > last cell was 500, changed to zero
switchover delay > all gears 5 seconds (p/n was set to 0)

hopefully that does something. Otherwise still shooting in the dark here. You can see this is happening NEAR redline. And to my knowledge i remember no lifting some of these shifts but the throttle seems to still be closing and being lazy. But im not 100% on that as the pedal shows i lifted.

Example of TB acting weird again per screenshots above (this time im near / at limiter, sometimes blowing thru it).
