MSD DIS-4 launch control with aftermarket standalone ecu

Hi, im having a hard time figuring the launch control setup on maxxecu when using the msd dis 4 box. I cannot soften the launch ignition cut like it used to be before using the msd box. No matter how much i retard the ignition inside the ecu, the ignition cut will be the same. Its like having a hard limit all the time when launching. Is the msd box overriding the setup? Does anyone else have this problem before? And i am very sure i turned off the 2-step setup on the rotary switch on the msd box.
