Default Advice from Data loggers please

I need some help from those who do data logging. I have an OBD bluetooth adapter and an app for my phone, but I'm not sure what the important things I should be monitoring are or what the proper values should be.

I don’t data log, but will start watching that this summer. You want to watch your KCLV, which shows whether your car is advancing or retarding your timing. These cars are sensitive to knock, fuel quality, etc. it’s always a good idea to watch air intake temperatures and give your car an easy drive if they are high. Then the regular stuff such as temperatures of fluids.

If your trying to tune, then I’m not educated enough to give advice.
