The control module then checks that the actual air mass/combustion matches that requested. If necessary, the PWM ratio is adjusted by multiplying it by
a correction factor.
The correction factor (adaption) is stored in the control module memory and is always included when calculating the PWM ratio.
The purpose is to have the actual air mass/combustion equal the request as quickly as possible after a load change. The adaption limit is 100 %.
