Hello I'm trying to determine what this map is for - air flow mass through throttle valve Kg/h?

I'm trying to make a ethanol blend map for this vehicle and need to increase the fuel delivery by a set % for say a E30 blend I hoping this is a map that I can edit to do this.

Y axis - throttle valve position %
X axis - rpm
Z - air mass in kg/h

I believe you are looking for Lamfa,kflbts for more fuel delivery which again depends on air quantity (more load more torque more fuel)

Thank you, One question and sorry if its obvious since I'm new to these systems. Will changing the Lambda maps change the value the ECU is looking for from the sensors or is the map a reference for a delivery value?

So if the map says 1.0 and and I change it to .9 will it target .9 or will is still target 1.0 with a trim of -10% when running on petrol?

is this me7.5 or?
