    For example, adding a turbocharger, changing the camshaft profile or a conversion to an alternative fuel. In these situations, a programmable KMS ECU can be wired in. The KMS ECU’s can be programmed/mapped with a laptop connected using a serial or USB cable, while the engine is running.
  • Page 5 WARNING: Disconnect the battery cables when you’re doing electrical work. Disconnect the KMS ECU from the wiring harness connector when welding on the vehicle. Make sure there are no fluid leaks and all connections are secured and/or tightened. Wiring and fuel system components must be mounted away from heat sources or shielded if necessary.

  • Page 9: The Injection Characteristic Diagram

    In the ignition spreadsheet, figures can be entered that indicate the ignition advance (in crankshaft degrees before TDC). This means that for any engine speed and any engine load, the desired ignition moment can be entered. KMS MP25(M)/MA25(M) manual Version 4.2...

    6.500 rpm, you can devide the 25 rows over this 6.500 rpm (example see right figure below). So the mapping will be more fine tuned for this engine rpm range. KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 14 1000 rpm. Checking with the timing light on cylinder 1 gives you 5 degrees ignition advance. That’s a deviation of 5 degrees which must be corrected on the reference point. The correct reference point is 90 – 5 = 85 degrees. KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 15 ECU can get damaged beyond repair. Many modern coils feature a built-in driver stage. However, if a coil without an integrated driver stage is used, the separate KMS ignition driver module with KMS partnumber KAC.05.001 will be needed.
  • Page 16: Rpm Limiters And Power Shift

    The hard limiter switches off ignition completely. For the KMS MP25(M) and MA25(M) management system the maximum rpm limiter is 20.000 rpm * *: with a 60-2 crank trigger pattern the maximum engine speed is limited to 12.500 rpm.
  • Page 17 Delay time: At the moment the Power-shift switch is activated, it is often desirable to have a short delay before the switch takes effect. This is because some resistance is required to build sufficient power for sequential shifting (charasteristic of sequential gearbox). KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 18: Engine Load Sensor

    This is normally used for turbo/supercharged engines . ➢ Main Load is: TPS + MAP as boost correction table Not available for MP25(M) and MA25(M). ➢ Main Load is: TPS + MAP as boost correction factor The ignition load table and lambda target are linked to MAP value (the ignition table for a turbocharged and supercharged engine should always be linked to MAP).
  • Page 19 7.5 ms at 75 kPa. If the engine runs on 50 kPa (0.5 bar vacuum) the injection value will be 50% of 10 ms = 5 ms. This is used for N/A engines. KMS MP25(M)/MA25(M) manual Version 4.2...

    The duration of enrichment can be set by entering the number of crankshaft rotations. The acceleration enrichment will automatically decrease at lower throttle valve opening speeds. Acceleration enrichment type 1 is always linked to ‘Engine load 1’. KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 23: Interpol. To Limits And Fuel Cut

    This does not apply when the speed limiters are set to a lower maximum engine speed. We recommend to use the standard limiters (see also section: 3.2.4.1.2.1 Standard Limiters) KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 24: Hardware Configuration

    The MP25M and MA25M ECU’s have a sensor on the circuit board. Please tick the box internal. If an external KMS MAP 75 – 120 kPa sensor is connected select external. It’s only possible to use a KMS 75 – 120 kPa sensor.

    (type a,b and c). Always check if the output type is the same as selected in this software. Type ‘a’ of the KMS UEGO Display controller has the same output curve as the KMS UEGO controller.
  • Page 28 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. KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 29 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.
  • Page 30 Above this main load value, there is no limit on the compensation between two samples. If 0.0 is set in here this function is not active. Recommended is to set this value after the engine is properly mapped, and to a value of 4.0 - 6.0. KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 31 Here you can input a compensation value (as a percentage) in case of lambda shut down due to error. This can be used as a protection for the engine against running a too lean mixture. Recommended value: 3 - 10% KMS MP25(M)/MA25(M) manual Version 4.2...

  • Page 33 TPS comes within a specific range of the nominal value. With level 2, a 95% accurate correction map is therefore created while a more precise one is created with level 1. Recommended: Map the engine first on level 2. This way you can create the correction map faster. KMS MP25(M)/MA25(M) manual Version 4.2...
  • Page 34: Boost Control

    (higher A/F) than the values set in this table. This can be used when KMS UEGO control is set active at cold engine/water temperatures to prevent the engine from stalling, by limiting the A/F ratio, when lambda control will try to reach a too lean target.
  • Page 35 Boost at MAP output 1.25 V: For inputting the boost pressure (kpa) at a MAP sensor (manifold pressure sensor) output voltage of 1.25 V. These calibration values are included with the KMS MAP sensors. Solenoid off is: If there is no current to the solenoid valve, the boost pressure will adopt either minimum or maximum pressure depending on the connection of the solenoid valve.
  • Page 36 Under certain conditions the boost pressure can exceed the set target pressure faster than normal. With this parameter you can enter the maximum boost pressure increase (in kPa) between 2 samples, before the turbo control intervenes to reduce turbocharging pressure.
