Help with hotend

I've recently bought a E3D hotend.
I'm still on the number changing game to get it right.. it seas I need to set at much higher temperatures to get the same results I'm used to with PLA, but that is not the reason for this post.
I have a different problem with it:
When I set a target temperature, the firmware raises temperature until it is almost there and shuts off 4 or 5 degrees before, expecting it to go up on its on the last degrees.
Problem is, the minute the heater shuts off, temperature only raises a couple of degrees before coming down, so it NEVER gets to the target temperature.
I have to manually lower target temperature for it to start printing.

Where I can change the shut off setting so It shuts off closer to the target temperature?
A G ccode would be even best.
I've been looking on G570 but it seams it is a diferent type of timeout.
Help?
thanks.

Hi Mac,

What value do you have in your firmware for the thermistor?

The reason for the temp cutoff too early, is the PID setting in firmware

I don´t know, how to fix this. Maybe there is an autotune option?

You haven't told us what electronics and firmware you are running, which makes it difficult to help you.
