Here's my (short) Megasquirt story of my 1990 Alfa 75 (Milano in the US) 2.0 twin spark track car.
In 2004 I bought the car for trackday use and I developed soon the ideas of supercharging it.
In november 2006 I bought a M45 supercharger wich lay on the shelf until summer 2008.
In that summer I bought the Megasquirt at Glen's Garage and started soldering it.
In august it ran on the tired stock 2 litre engine, doing 150hp and 196Nm.
The next race on the TT circuit in Assen, the engine died of weared bearings and a hole in the engineblock.
That was the best oppertunity to start the supercharger project and I started measuring and building:

Plan "A" was to use an water to air cooler, so I converted an 75 turbo cooler, but that thing leaked somewhere.
So I changed that to an air to air cooler, much easier and lighter. After some engine troubles, I changed the drive pulley for some more boost:
