As mentioned on the Roll Call forum - I live in Houston and several years ago I bought a well-used Cookshack (Model 105 circa 1995) smoker when the historic downtown Houston Club closed/moved. Unfortunately the motherboard died and replacements were pricey. So today I swapped out the guts for a TA4 PID. Haven't done the autotune yet but so far I thank it has great potential. BTW - This is a very helpful video that explains how to program the TA-PID Old wiring in place Old wiring removed - see all the switches Testing the PID and probe in ice water New front - wish I had a good before picture - all those holes were mini-switches or push buttons. New look - she may get some paint!
