Default Just a thought

I was wiring up the ecu for my EJ powered sand rail today and had an idea. The ecu has a wire that is connected to the start position on the ignition switch. Without this wire connected the engine starts very hard, and if cold not at all. I think this wire must richen the mixture while cranking. It might also retard timing a little. My thought was to hook this wire up to a switch that comes on at a certain boost level thus retarding timing and richen the mixture.

Any other thoughts? Does anyone know what exactly this wire does?

Where does the wire run? From the ECU to where?
