2019 Supra SL450 having issues getting to surfing speed

You can adjust the “launch” system set points. Specifically your crossover speed where your plates transition from launch mode to surf mode.

But too much stern weight and not enough bow weight is your obstacle.

It's my understanding that the tabs are not used for launch in surf mode?
if you look here in the settings it says launch is only used when swell surf is off.
I think these settings only effect the center plate.

I really don't like launch mode without ballast it makes it jerk when it retracts the tabs so i toggle it on when I have full ballast and need to get on plane, but sometimes it doesn't respond and I have to keep trying until they finally deploy. Really annoying. Can't figure out what I'm missing.

I think it has to do with weight, and the boats ability to get on plane. Something with the inclinometer the boat uses and the software that controls the takeoff to get it to plane. It uses the plates in rear all deployed simultaneously to get it on plane, so I wonder if having too much weight towards the back messes it up somehow, the software sets a speed to get the boat out and to level, if it cannot get the boat level despite speed of 11.4 in my case, I wonder if it sets to that speed and waiting for the sensors to show leveling while its not happening because too much stern weight. Anyway, its my theory and I'm sticking to it.
Anyone else experiencing this?

Haven't experienced that but there are definitely some SW glitches that have come up. I was in surf left at 11.4, shut completely down including turning the battery off so the kids could swim. Started back up and was in surf left and the system glitched. My wife was pulling me at 17.4 with a wake board wake but ballasts loaded for surf. Had to shut completely down and reboot.

We haven't had any issues with the 450 getting up on plane yet.

My only real glitch is using the touchscreen to change volume or speed, sometimes it runs away from me.
