Overflow injection time
You get overflow of injection time when one injection takes more time than the time for two rotations.
The time of these two rotations is the maximum injection time because the upcoming rotation is for the
next injection.
For example an injection time of 23 ms and an engine speed of 6000 rpm. The time of 2 rotations =
1/(rpm/minute)x2 = 1/(6000/60)x2 = 20 ms. The overflow is 23
– 20 = 3 ms.
When choosing inje
ctors it’s important that the flow is high enough so that injection time doesn’t occur.
When there is a correction on water temperature injection time overflow can occur when the injector
flow is to narrow.
Lambda control
The total time that the maximum % increase or decrease in fuel has been reached is recorded here as
MaxIncLambda or MaxDecLambda. The values for maximum % increase in fuel or maximum %
decrease in fuel are set in Lambda Control (see section
The time behind MaxIncLambdaError or MaxDecLambdaError is the total time Lambda control was
shut down as a result of maximum time at increase or maximum time at decrease in fuel. The time
lambda measures maximum increase or decrease before shutting down lambda control can be set as
Max time at max increase or Max time at max decrease in Lambda Control (see section
5V sensor supply
The time the 5V sensor supply is less than 4.8V is recorded here. Also the lowest sensor supply
voltage is shown here.
