Default Reduce acceleration in Curtis 1234SE Controller ? 72v EZGO TXT 2020

I have an EZGO 72v TXT 2020 when the speed switch is in 'Rabbit' mode will literally lurch/accelerate almost lifting the front wheels off the ground. While I get the chuckle of a launch in 'rabbit' mode, I'm going to throw a guest one day!!

I have a Curtis 1314 USB programmer installed in a PC at the OEM level.

I've looked at the parameters and it's not obvious to me how to adjust the acceleration in the 'rabbit' mode. Acceleration in the 'turtle' mode is slow and just fine and the same in the 'rabbit' mode would be ideal.

Appreciate any help.

Change the Full Accel Rate LS to 1.5 and see if that helps.

I cant save any change to the 1234SE controller. I'm using a 1314 USB setup on my PC at OEM level.

Does that make sense? thanks for your time.

Can you take a few more screen shots of the parameters from the start down? I'm not for sure your at the right location.

If you open the control file you can export it to like Excel or Open Office. Open it in that and it will tell you what level of access you need to change a parameter.

Me? Not sure if I have one for that controller because it is a 2020 but I know I would have another one.
