I have been looking at lots of Zetec ignition maps over the past few months. I have converted various maps to GEMS format (I have a GEMS miniDLS unit). I have been road testing the car with different maps and air/fuel meter connected to ensure I didn't damage the engine. Anyway the map below was based on a Megajolt map and it works very well. So here's the info for others to use.

ps my rev limiter is set to 7200rpm

Thanks for that. I have saved the file and will upload it when i get my Zetec in me motor next winter. I'll be using R1 carbs so should be similar to yours.

Do you have an idea of your BHP?
