1.4 Input Channels
Only active (0 to 5 V) exhaust gas temperature sensors are supported.
See chapter Initial Data Application [
}
22] for further information and calibration ex-
amples for different sensors.
1.5 Output Channels
The MS 25 Sport has 8 injector power stages on three banks. Only solenoid valve type
common rail injectors are supported. Injector current profile must be calibrated for used
injector type (CRIN1, CRIN3, CRI2.X, ...).
1.6 Power Supply
Please ensure that you have a good ground installation. That means:
– A ground that has a solid, low resistance connection to the battery minus terminal.
– Connection should be free from dirt, grease, paint, anodizing, etc.
– Use large diameter wire.
– More metal-to-metal contact is better
Connection of the power supply
The following notations for power signals are used:
– Term 15 is a switched battery rail controlled by the Engine On-switch.
