Adaptation Values

Adaptation Values are stored by the EMS2000 in order to maintain an "ideal" air/fuel ratio.

The EMS2000 is capable of adapting to various environmental conditions encountered while the vehicle is in operation (changes in altitude, humidity, ambient temperature, fuel quality, etc.).

The adaptation can only make slight corrections and can not compensate for large changes which may be encountered as a result of incorrect airflow or incorrect fuel supply to the engine.

Within the areas of adjustable adaption, the EMS2000 modifies the injection rate under two areas of engine operation:

• During idle and low load mid range speeds. (Additive Adaptation)
• During operation under normal load to higher load at higher engine speeds. (Multiplicative Adaptation)

  These values indicate how the EMS2000 is compensating for a less than ideal initial air/fuel ratio.

• If the adaptation value is greater than "0.0ms" Additive or 0% Multiplicative, the EMS2000 is trying to richen the mixture.
• If the adaptation value is less then "0.0ms" Additive or 0% Multiplicative, the EMS2000 is trying to lean-out the mixture.
