Generally speaking, the ramp settings determine how aggressively the fuel pump voltage is raised or lowered. The Lo settings cover the bottom ~20% or so of the RPM spectrum, the Hi covers the Upper %20 or so, while the mid covers the ~60% in the middle. These depend on the ramp switch settings which are not available to users in the current software. Up or down is self explanatory. The higher the number, the slower the engine will respond to throttle stick movements so the fastest possible spool times will occur when these settings are set to their minimums. That being said, if an engine is running in less than optimal shape, you may need to increases the ramp settings.

Please do keep watch over the shut down data. It is often the smoking gun when diagnosing a problem.
