I don't think the timing of the element going on & off can help, as far as chips smoking:
If the element comes on more often to maintain a more even temp, it would never be on long enough to make the chips smoke.
If the element's on off stroke is farther apart, it makes the chips smoke on the way up, and they stop smoking on the way down.
This is why the MES chip-burning set-up works much better in the Winter. The element has to run a little more often & longer.
Two things can help you get better smoke in an MES:
#1 Take it apart & rip all of the insulation out, so the element has to run more often.
#2 Get an
A-MAZE-N-SMOKER, fill it, light it, and sit back with a nice cold brew.
I choose #2.
