Ok, i'll break it down a bit.
As far as the ecu itself is concerned, it's very capable and its limits are well, well beyond anything you could ever ask for on a 16v engine. I use another variant of the same ecu on my daily driver GTV turbo and i'm really happy with it, no problems whatsoever.
About the distributorless ignition, it's really simple. Pull the distributor out, plug the hole with an appropriate size core plug, and remove the original coil. The neatest thing you can do is source a set of coil packs (two seperate double coils) from a 33 1.4 fitted with a marelli ecu, along with their mount. They mount on the same spot as the distributor, use the same bolt hole, and you retain the original spark plug leads, it's all plug'n'play really. If you're not able to source that, any 2x2 coil pack will do just fine, but may require modification of the spark plug leads.
About the loom, it's an adapter loom, 10' long, megasquirt plug on one side, Bosch ECU plug on the other side, with the point being that you retain your original ECU harness with really minor modifications. You also need a TPS sensor and an air temp sensor, again you can use the ones from the 1.4 IAW, but anything else will do as well, and they are dirt cheap.
