5ohpatrol is right, every computers advance is different as well as their total timing. There are a few basic rules of thumb that people look at. One is WOT timing. The EEC adds 15-16 degrees of timing to the base timing. So if base is 10 degrees plus the EEC of 16 , total advance during WOT should be about 25-26 degrees. There are certain EEC's out there with more aggressive timing/fuel maps in their. Most people get the A9L or A9P. I had the oppertuninty to see the timing MAP of a A9L at WOT. From what I could see, the EEC doesn't put in all the 16 degrees at WOT. It waits to about 3000 rpm until its all in. So thats where the spout out, high base timing helps. It will give you more power due to higher timing in the curve. If you run a chip and remove the spout, you are only effecting the timing and timng only. The fuel maps, if changed, will still work fine.
