Kit,

Can you explain how the user edits the tables? Most engine controllers I have seen require one to enter values in a 2-D table ("engine map") where fuel flow is a function of 2 variables - rpm and manifold pressure. Ditto for spark timing. This seems tedious and error prone to me, since there are many cells in the map and most people can't emulate a dyno while driving their car. I would prefer dealing with smooth functions (curves), say a 2-D plot where one pulls it up or pushes it down in regions and the whole surface follows, kind of like sculpting a car body on the computer with curves. However, I am just going by what I have seen in manuals and have yet to play with my Holley Commander 950 which uses the old map method. I can see why people love the new "self-tuning" controllers.
