VESC 6 MkVI HP max current limit

I wanted a bit more startup torque on my VESC build and was wondering if the current limit can be pushed a bit more than 160 motor amps safely. I've red that the VESC 6 MkVI HP uses IRF7749 n-mosfets (https://www.mouser.de/ProductDetail/Infineon-Technologies/IRF7749L2TRPBF...) which are 200A rated and for 375A/800A pulses so 200A should be fine or how does that work? Am I missing something?

Thanks!

There is a reason why the manufacturer limits max current in firmware. If you want to push more, loose your warranty and risk a blown controller you can flash the no_hw_limits firmware in Firmware tab. You need to enable "Show-non default firmwares" on this page. Changing time constant for example can also make you accelerate faster depending on your setup.

I am aware that there is a limit for a reason, but I thought that the limit may be set quite conservatively, and can thus be pushed a bit more.

FETs rarely get near their datasheet limits in most situations. You can sometimes fry them other ways with big currents, voltage spikes could occur if you push higher currents than the caps can cover when switching.
