Begs the question, how does a mapper know where to set the cut off level???
his experance,,,

Come on Gareth, you can do better than that
Based on what been said so far, its good to have some fuel, but what determines how much and at what point?
Is it really just a calculated guess or is there a measure taken to determine it???
The only measure thats likely to be relevant is EGT as thats the only hint you have at piston crown temps, but there isnt a direct correleation between the two.
