I am not too sure that is right. The latter ECU use the atmos sensor to change the gearbox maps, but I think it still uses the other inputs of throttle position sensor, RPM, MAF to determine the load.
The later phase 11 autos have another speed sensor on the turbine shaft to determine the difference in speed between the impeller and the turbine that gives a direct read of load.
