Noise related issues?

Hi, I have a Flipsky 200a waterproof vesc and I have some weird problems with it.

1. Recently I started using HFI with values fairly close to the defaults on 12s and with a max motor current of 180a. I used my laptop plugged into the USB port to set it up, but when I would push the throttle and the motor would start up, the vesc tool would disconnect. On this Flipsky vesc, all of the data wires run very close to the power in wires, so could this be causing enough noise to mess up the usb connection?

2. I am using an Arduino to control the vesc with a ppm signal and it works fairly well at the lower and upper parts of the throttle range. However at around 30-50% the signal gets really jumpy and the vesc will randomly read a value of 70-90% instead of the 30-50% for a split second. This seems like noise to me, but it only happens at medium inputs and not the higher inputs where there would be more current.

3. This one is more unrelated but on my Arduino, I am using its analog input to read the position of my pedal. When it is plugged into and powered by my laptop, the pedal seems to be calibrated perfectly and has a stable reading. However when it is powered by the vesc, the Arduino reads 2 or more percent low and the reading is a bit more shaky. Is this caused by the presumable difference in voltage or by noise in the ground of the vesc
