This may seem silly as we will be adding a bunch of Channels that we just removed, but we will comment on why we are adding each one and we will add them in a certain order (although yes we could have just reshuffled the ones we already had)
Arguably the most important sensor on our LS engine is the Coolant Temperature. I was raised thinking it was the Oil Pressure but the PCM don't even monitor the oil pressure on the Gen 3 trucks, so there you have it. A lot of Hot Rodders would vote for the Tach, but nope, the Tachometer slides down the list also.
1. So let's add this bad boy in, either right click in the blank Channels pane and select Add Channel from the little pop up menu, or click the gray gear with the green plus + sign next to it on the top menu.
2. This will bring up a Channel Selector, so let's type Engine Coolant Temp in order to narrow down our choices, we could hunt and peck for it using the drill down method, but I find typing in what you want is quicker.
3. Then double click the Channel you want.
Once added if you try to add the same Channel again it will appear highlighted in blue, simple.
