Jdroberts You are more than welcome to share your knowledge through these forums and as Bykfixer has mentioned it would also be great to get the buzz back into the site.
If you would like to populate a separate section within the forums for performance mods, etc then we can set that up for you.
Meanwhile, feel free to share you build with us (photos as well) and I'm sure your posts will get some interest and feedback
With reference to the ECU, I have only personally used one before and it was Emerald which was easy to download maps onto and even the basic running setting was quite close to where things should be (Fuelling, Ignition, etc).
There are plenty of other programmable engine control modules available out there nowadays at reasonable cost
