I do the same thing.

I sometimes watch my Pulse Width instead of LTFT.

When i know my car's running right i have it on either Manifold Pressure/ KR or IGN Advance / KR.

I like to know how things are doing when i go WOT and i like to know how high my advance is at cruise.

It's all really dependent on what your wanting to watch. If your car is drinking gas like an alcoholic drinks his Vodka then you wanna watch the IPW ect...

When i'm at the track i put it on Trans Temp and IAT in the pits so i can see how long i need to wait for it to cool down.
