How to get new M307/M301 to apply

Hi, I'm trying to tune a pesky unstable heater. Autotuning is unstable for various reasons, so I am having to tune M307/M301 Parameters by hand.
Do I need to turn off the heater to change the heater model/PID parameters or can I change them on the fly? It's hard to tell whether the new parameters have taken effect.
If I run a M301 to try some Legacy PID parameters and I want to switch back to an M307 heater model afterwards do I need to reset the board before doing that to remove the overrides or can I just send an M307?
You should be able to send the commands at any time and they should take effect without a reboot.
What problems are you having with tuning?
