Default ECU pinouts and IGN retards

Does any one have a pinout for the fiesta rs1800 ECU and the ignition retard pins. I know other ecu's has various pins to ground for countries with low octane fuel that will retart the ignition by a few degree's

Also how does the factory rev limiter work?, is it fuel or spark it kills and is it every other revolution of the crank etc.

Tried a web search but could not find anything usefull

I do not know the pinouts but there are at least two different types; one for external EDIS and the other for internal EDIS.

The rev limiter is via fuel cut. There are usually two stages; half fuel where every other injector firing is cut and no fuel where all fuel is cut.

Assuming this is for nitrous, do you even know yet if you NEED to retard the spark angle?
