Closed Loop Compensation (CLC) map - Fuel Adaption

The

Closed Loop Compensation (CLC) map

is a map where the fuel pulse width is

dynamically adjusted to provide the engine the desired air/fuel ratio by applying a
multiplier to the fueling to correct for any error which may exist in the base fuel map or
dynamic flow changes in the rails or injectors. It can be continuously adapted via the O2
sensor, or it can be manually calibrated for open loop operation or to speed the process
for pro users.
