Full throttle PWM output different for front and rear motors

Hi all,

I was trying to calibrate my motors vertiq motors which require me to activate them at full throttle. My front motors weren’t beginning to calibrate and after I hooked up an oscilloscope I realized at full throttle the front signal lines read 1850us and the rear was at 1999us (PWM_MAIN_MAX=2000us). I have checked each main rail output’s trims, and confirmed all of the min/max/disarmed values map to the global parameters.

Hoping that someone can point out a parameter I’m missing. Any help would be appreciated.
