Hi
Im just wondering if anyone knows where to get a copy of the Aston Martin ECU (Emotion control unit) or something similar to start a car. Would love to find even a copy of the style where you insert the key into the button.
Thanks for taking your time to read this

Edit: Heres a picture

I’m not aware of anything ‘off the self'.
To fabricate something you’re looking at a lot of work, both the look and the technical.
From a technical point of few you could you a RFID tag and a reader that then fires in to a relay then to the ignition.
Or maybe use one of the remote engine start kits. Pull apart a key fob, and put the electronic guts in a plastic block, that when you push it in a holder it in turn pushes the starter button somehow.
Or if you don’t mind using a key as well (first) just make up and block and holder that pushes a engine start button..?
Hard work but it would be trick
