Tom,
Since it's self learning there's not much for you to do but get the initial timing set and let it learn. One thing I suffered through - my directions said to take the computer out of play (turn the ECM timing "off"), set the timing to 10BTDC, then put the computer back into play and don't turn it off again. I learned the hard way that when you turn off the ECM timing, the severely retarded spark puts tons of raw fuel into your headers, and they get very hot, very fast. If you have any type of coating on them it will be toast. While their way works you can also set your base timing just fine by leaving the computer in play, taking your rpm to a steady value, say 1500rpm, note on the laptop or handheld unit what the computer says it wants for timing at that point, then using a good dial back timing light adjust your distributor to that value and lock it down. Now your base plus ECM advance will be dead on at all ranges, and your headers will still be happy, too. That's what I'll do the next time....
