Opinions on EFI system

I've used a megasquirt on two extremely different vehicles. Worked very well, and fairly easy to learn.

Most current systems are "self learning". What that really means is that you can get most of the basic tune done simply by driving around under various conditions. The key here is "most". That last 10% or so requires some work on your part to get it where you want it.

How well do these new systems deal with high altitude? My Accel system ran great at sea level but was never taught (before self-learning) about living above 5000 feet and couldn't get out of its own way at 10000 until the tuner closed that remaining 10%
