Any project goes from being an idea to a real project after the first parts purchase. Today I ordered a scrap factory ECU for the car from Ebay from which to unsolder the connectors to the wiring loom (£15) Looks like this project has started! I often think that my love of making things and tinkering could, if uncontrolled, turn into a full-blown addiction. This is the first pint in a yearlong alcohol binge. Oh Dear...

I have also ordered some PCBs from dirty PCBs to try out this open source wideband lambda controller https://www.14point7.com/products/slc-free.
