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
