Even lambda.
Why exactly would it have to be different?
Higher torque usually indicates better 'breathing' in that range, higher Volumetric Efficiency. More oxygen molecules per revolution.
So if fuelling adjusts to this, it will pair (say) 20% more fuel molecules to make up for 20% more oxygen molecules.
Lambda is just the
ratio, it stays the same :wink:
The extra heat that might need absorbing in the combustion chambers (we're talking high-boost applications here) will be absrobed by the Water.
That is the whole idea behind this forum, isn't it?

The Courtenay maps aim for 0.79 lambda for safety. A bit too safe I think though.

we've already been through this, and it is 0.85 that we want in this case.
Their 0.79 is a good choice for a non-WI setup.
