I use:
Fwt - to monitor temps as I have installed grill blocking.
LOD - to help me learn best acceleration schedules for hills and pulsing.
*** when I'm learning acceleration settings, I substitute LP for Fwt to help learn at what TPS Open Loop begins on acceleration (and make sure I don't go there!)

TPS - to hold constant Throttle Position for DWL and to learn position for acceleration schedules.
