Auto Tuning - Group Results

[Carp210]

SI #2 Auto Tune (800 watt)
By passed with fixed probe mounted 2" from top
Auber WSD-1200 GPH
Air temp 44 degrees
Two wet bricks on 2nd shelf
Mini loaf pan/ hot water next to wood box
Foil on bottom of #2 and top of wood box

Results
P=68
I=623
D=155

Update:  I had problems with the above tune. Temp ramped up and over shot target by 55+ degrees before I turned Auber off.
This happened during a rib cook and in hind sight it was probabley caused by wood catching fire.

Did another tune and changed from bricks to pan of wet sand.  This seems to be working well.

New values:
P=57
I=826
D=206

I ran my auto tune--did not watch it like a hawk so don't know all the max temps etc....
Here is my set up for my SI #2
Auber WSD-1200 GPH using WS-SENSOR11 wall mounted probe.
By passed control, with wall mounted probe 1 1/4 inches from top. (Sorry, just want to be different)
Three bricks second from top shelf with a beer can of water on bottom shelf centered above heating element.
Ambient Temperature:  44F
Program: C-1 140 for .5
      C-2 225 for 2
      C-3 140 for 5
Ran for about 1.5 hours
Results
P= 57
I= 853
d=213

Let me know if this is not Good--appears to be close with most.  Thanks for all the great information in this forum--going for first smoke tonight!

First picture is my seasoning run--break in
Second is Set up of Auto tune
Third Auto tune is complete and cooling down---I think.
First smoke coming soon.

Dale,
Your numbers look good. When you do your smokes put the water can on the bottom rear right next to the fire box.  A foil mini loaf pan works well for a water pan.  Let us know how it ramps up to target temp and if it over shoots.  Should settle and lock on your target till the end.  Once you are comfortable it's set it and forget it.  Enjoy your #2 and don't forget to post some photos.

[TexasSMK]

Done that--thanks Dave.  On my second smoke--longest to date--my temperature exceeded my high temp by 7 degrees initially, but cooled to target and held steady for four hours.  Very happy with it.

Numbers look good to me, too, Dale!  Now go smoke something!

Here are my results:
SI #2 Auto Tune with new installed element (800 watt)
By passed with fixed probe mounted 2" from top
Auber WSD-1200 GPH
Air temp 77 degrees
Two bricks on 2nd shelf
Mini loaf pan/ hot water next to wood box
Foil on bottom of #2 and top of wood box

Results
P=76
I=600
D=357, from what noticed in this group this D=357 seems high??

[Mike]

Redid the test for comparison.  Same set up. I gues I'm gonna have to try again in the morning

P=76.        ,
I= 11.....very strange number??
D=252

First test P=76, I=600, D=357

Something must have been off, Mike.  The I value is way off the mark.  Your first numbers looked much better.  Why did you do it twice?

I don't think it's too far out of line.  I'd run a "simulated" cook to test it.  Use the same setup as your autotune, but set C01 to 225 and time 2.0.  Zero all other steps.  Turn it on, and see how it holds temp.

[Mike]

Will do, the reason I did again was because of the 357 didn't come close to any of the posted results?

I'll run it again in the morning and see if it holds..

Mike

[DivotMaker]

Gotcha, Mike.  I should have picked up on that.    I'd still do a simulated cook before an autotune.  I think your "I" number will work.

[Mike]

Tony, I did the sim. And the Auber/SI2 held at 225 with no issues..I believe I'm good to go and by the way the new element heated up fast

I did recheck my numbers without running an auto tune, these numbers seem right in line with most.... I wonder where did that "11" come from??  Maybe one too many beverages and not wearing my reading glasses..lol....
P=64
I=600
D=252

Thanks

Mike

[DivotMaker]

Great, Mike!  I put the 800 in the ol' #2 last weekend, and boy, does that sucker heat up fast!  I did a strip clean (EZ-Off about once a year) and re-season, and was up to 250 in less than 20 minutes!  More to follow on all I did to the smoker last weekend!

[TexasSmoke]

I finished by autotune today on my #3 with a perm temp sensor (1 1/2" from top center), Stock control and WSD-1500GPH:

90* ambient, 6 medium bricks (Tried to approx. sixe of brisket),
2nd shelf from the top, water pan, drip pan, foiled bottom and wood box

RESULTS
P: 72
I: 600
D: 271

My results seem a bit different that others.  Does it look OK?  Should I have used 3 bricks like others?

Also the unit did not turn off when done and stayed at 140 WAY longer than 30 minutes.  I am not sure if the autotune was still flashing when it switched to 225.  I checked the menu and the AT was = to 0 so I think I should be OK for my next smoke. 

I am doing a brisket tomorrow  Can I do an autotune on my normal brisket program?

[DivotMaker]

Ron, the unit doesn't turn off when done autotuning, it just goes back to the regular program (not flashing At).  Also, when it goes to step 2 (225), it's probably not done.  It will continue until it finishes, regardless of the step. 

You can autotune with any program.  Try it with your normal brisket program, if you want.  I'd probably just try a cook with the settings you got, and see how it does, before re-doing the tune.
