KMS MA-5 manual
Version 5.1 27
Overrun Lock time:
When an engine recovers from throttle overrun, it is usually necessary to wait a while before
reactivating the A/F ratio feedback control in order to allow the engine to stabilize. This delay can be
input here.
Recommended 0.3 - 1.0 sec.
Minimum watertemp control on:
The coolant temperature above which the A/F ratio
feedback
control activates. If a KMS UEGO lambda controller is
used, the
lambda control can already be activated at cold water
temperatures. If your using a standard BOSCH lambda sensor (narrow band) is used, it is
recommended to activate the lambda control only above a water temperature of 60°Celsius.
Delay from start to on:
Oxygen sensors require a certain warm-up time after engine start.
During this warm-up period, the A/F ratio feedback control cannot function. The warm-up period in
seconds can be set here.
KMS UEGO recommended time: 10 - 15 sec.
Standard BOSCH recommended time: 20 - 30 sec.
Throttle Red. To Lock:
During rapid reduction of the throttle position (without
entering throttle overrun state) the air fuel ratio
feedback control has to be deactivated in most
engines. At a certain deceleration speed the lambda-
signal is disturbed due to less efficient combustion.
Here you can specify the decreasing rate that triggers the de-activation of the lambda control. The
value input here represents the decrease in engine load between 30 ms.
Recommended value: 0.3 - 1.0
Red. Lock time:
If the A/F ratio feedback control has switched off during rapid deceleration, the control loop will close
again (if the throttle position stabilizes or increases again) after a time specified here.
Recommended: 0.5 - 1.0 sec.
Throttle Inc. To Lock:
During rapid increase of throttle position the air fuel ratio feedback control has to be deactivated in
most engines. Here you can specify the increasing rate that triggers the de-activation of the lambda
control. The value input here represents the increase in engine load between 30 ms.
Recommended value: 0.3 - 1.0
Inc. Lock time:
If the A/F ratio feedback control has switched off during rapid acceleration, the control loop will close
after a time specified here.
Recommended: 0.3 - 1.0 sec.
