don't over-think this. You will probably only have to autotune it one time, and then never mess with that again.

You are planning to to a wet-test of everything before really using it, so I would wet-test it with a normal amount of water, like you would have in there on brew day.

- Calibrate the probe in ice water.
- Then install it in your kettle and put your water in.
- Using default PID parameters, let the PID heat the water up to some set-temp.
- Enter auto-tune mode as you get close to that set-temp (I guess this is mode is AT=1 according to the text you pasted earlier).
- Let the auto-tune finish. be patient and don't interrupt it. it might take a while.

After that, you should be good to go for tuning.

I would then suggest trying to heat water to 300*F or something impossible and let the PID start boiling the water. You can then check that your probe is accurately reading 212*F when it's boiling.

Switch over to manual mode and play around with controlling the boil strength.

You're done then.

Thanks for the run down - I will follow your suggestions.

I think I will brew propane Sat, then Sunday cut my holes and do the wet test. I was hoping I could just charge in and use it Sat. Probably pays to do a wet test with water, not wort.

Will let you know how it goes

So I will start with the pics of the holes - thanks for the advice. These holes were super easy to make clean. I used Bobby's tips on can of oil and dipping the bit:

And now for some brewing shots:
The pot, my buddy and a curious neighbor and my good pup,


And for Walker,..

Didn't want you bragging about how ugly your set up was without showing you my ghetto-tastic "grain silo" - HA (last pic)! Works great thought takes two fillings for most double batches. I am guessing between 12-15lbs of grain in the silo.

Will do!

Shot the heat sink with a temp laser and the hottest it got with no fan was 190F. That said, the 5500w element is perfect for a 10 gallon batch, but it is not a ripper of a boil, which is actually good. However this set up would not be ideal for a 15G batch (you would probably need more power). I ran a 90 minute boil with 14G start volume and it gave a nice boil, as you see in the pictures.

Instead of having to adjust with the percentage in manual mode, I need to keep the element at 100% for the full boil. It will be interesting to see how the element fairs for its life cycle.

All said I am VERY happy with it.

I'm surprised you don't think it would do 15 gallons with 5500w, I do 15 gal with mine and have it down around 65% or else it will shake the whole kettle and spit wort out the top.

I'm not sure where you are located, but I think you might benefit from getting the kettle off the ground. I know you have a piece of wood under it, but it just seems that the blacktop could be acting as a massive heat sink.
