Did note that it I use the control knob when it is frozen up, once it unfreezes it seems to go to that screen or whatever screen it would be on depending on the know turns. Another problem that is going on now is after so long of it being frozen, the screen goes completely blank for a bit and then comes back on. It also looks to not be displaying the Boost pressure properly. I am using a GM Sensor and when I hit boost I get over boost error saying I hit 24psi but I was not even at 14 psi based on my boost gauge.

I wonder if the freezing up is related to the data it is receiving from the ECU. What can I do to turn off reading the ECU to see if that helps at all. Only data I really need constantly from the ECU is knock and trims so am I able to disable reading all the other data and just have knock and trim readings? 90% of the data shown and displayed is really useless for everyday use. So a toggle to turn items off to increase the system response may be best if that is an option and possible.
When you purchased an old generation LCDBC unit from someone else, it's harder for me to diagnose your problem, as there's been many improvements on the hardware over the years (such as better OBD2/MUT cable, better serial chips, better DB9 connectors, etc).
Adjusting the "ScreenRefresh=" to a low number will update the screen faster than you can read it. However, if you have a ECU communication problem, it will add additional delays as the LCDBC is waiting for a response from the ECU.
It also sounds like static electricity discharge is causing you grief. If your knob is not installed, and you just use it in your hands, you will cause static discharge and that will cause a microprocessor reset, or other strange behavior.
Your old generation LCDBC is obviously not functioning correctly with the list of problems you have given. It might be a good idea to reflash again in case static electricity has corrupted the software on the microprocessor.
