Noting your geographic location, I think I may know who your talking about, Popp's. If so, you'll have better luck with PRP. The EEC-V doesn't work as well with open source stuff as the EEC-IV did. For one, there aren't any public technical doc's for the V, there are for the IV, but the architecture is quite different.
If you understand how the systems interact, air, fuel spark, I don't think you'll have any issue self tuning. Most of your questions will revolve around finding things and figuring out how to sort the data you are logging ... for which I love the new LiveLink (look for my thread about it to see how to sort things and make it work well).
