Ground loops. Bad ground connections can cause many problems, such as noisy readings from analogue sensors or problems with trigger errors. EMU device has several kinds of grounds. Device’s grounds (pin B17) is a ground used to power the device, analogue ground (pin B18) is the ground point for analogue sensors, and power grounds (B24, G17 i G24) are used to supply power outputs and ignition outputs.
Page 32: Inputs And Outputs
Stepper motor outputs are 2 state output (ground / +12v) and have built-in flyback diodes. Due to this fact it is very important to assure that devices (relays, solenoids, etc.) connected via stepper motor outputs will not be powered if the ignition is off. Otherwise the EMU device will be powered via the embedded flyback circuit.
Page 33: Analog Inputs
Analog inputs EMU device has two kinds of analog inputs. The first type is fixed for given sensors like IAT, CLT and TPS. The second type is universal one. It could be used to connect any sensor in the voltage range from 0-5v or as switch inputs for activating different strategies like ALS, Launch control, etc.

Page 37 What is characteristic for this sensor is the fact that it has polarity, which is crucial when connecting it to EMU. Inversely connecting it will prevent the synchronization of ignition. Signal from such sensor, especially with low speeds, where its amplitude reaches several hundred millivolts, is very sensitive to interference.

Page 53: Fueling Parameters
Directly to EMU we can connect high impedance (Z) injectors (>= 8 Ohm). Up to 2x Hi-Z injectors can be connected to one Injector output. In case of Lo-Z injectors (<4 Ohm) we should apply a current limiting resistor (4,7 Ohm 50W) for each injector or additional external Peak and Hold controller.

Page 69: Trigger Edge Selection
For proper signal processing, it's important that you select the correct trigger edge for the crankshaft and camshaft position sensors. The EMU is equipped with a Scope tool which is useful to verify that the signal is being decoded correctly.
Page 70 Edge selection for camshaft trigger wheel signal Frequently, when a variable valve timing system is present in an engine, incorrect signal edge selection makes proper signal decoding impossible. Incorrect scope for camshaft trigger wheel signal The scope above shows a camshaft trigger wheel signal decoded with equal distances between signal edges (teeth).
Page 71 Edge selection for multitooth trigger wheel signal When a trigger wheel with equal tooth spacing ( multitooth ) is connected to the Primary Trigger input, and synchronization is based on a camshaft trigger wheel signal, edges should be selected in a manner that gives the maximum distance between Primary Trigger and Secondary Trigger edges.
Page 72: Secondary Trigger
Secondary trigger parameters are used to synchronize the crank position to the engine cycle phase. This allows you to use full sequential ignition and injection. Camshaft position sensors are also required for using VVTi/VANOS systems. The EMU device supports several different secondary trigger wheels, and supports VR as well as HALL/Optical sensors.

Page 106: Vvt - Variable Valve Timing
VVT – Variable Valve Timing Typical variable valve timing system is based on PWM controlled solenoid that regulates the oil pressure applied to an actuator to adjust the camshaft position. +12V Sample connection of single PWM VVT control solenoid PARAMETER DESCRIPTION This parameter is used for camshaft starting position calibration.
Page 107: Double Vanos
The neutral zone where no DC change is performed Double Vanos By default Double VVT solenoids (Vanos) are controlled by +12V (High side). The EMU controls solenoids by switching them to the ground (Low side). In this case it is required to change direction of diodes that are built in into solenoid connectors or solenoids module.

Page 109: Boost Control
Boost control has two sets of 3D tables to permit switchable boost sets. These tables can be changed by a switch connected to one of the analog inputs of the EMU. +12V...
Page 110: Pid Parameters
DC re map and does not use the Boost target table. Closed loop control strategy Closed loop control bases on PID control. The EMU will aim to obtain boost pressure defined in Boost target table by reducing or increasing the duty cycle from the Boost DC ref map. Another strategy to use in the closed loop operation is to use the Boost DC error correction table which allows you to correct the value from the Boost DC ref table as a function of current boost error.
Page 111: Dc Ref Table
DC Ref table Boost DC reference table defines the duty cycle of the boost control solenoid as a function of throttle position and engine RPM. If closed loop control is enabled, boost pressure will maintain a defined boost target. Boost target table Boost target table defines boost pressure as a function of throttle position and engine RPM.
Page 112: Dbw
In order to use the electronic throttle (DBW) you need an additional control unit. DBW Module (driver) which controls the engine throttle based on the control signal from the EMU. The module input is connected to one of the EMU outputs (injector, AUX, stepper). The electronic throttle is equipped with two potentiometers that determine the current percentage of its opening.
Page 113: Table
Table P table defines proportional gain of PID controller in function of current throttle position and position error (the difference between target and current position). I Table I table defines integral gain of PID controller in function of current throttle position error (the difference between target and current position).
Page 114: Traction Control
TRACTION CONTROL Traction control strategy allows engine torque to be reduced in the case of wheel slip. Wheel slip is detected based on engine RPM increase. For the traction control strategy to work correctly a VSS sensor or gear sensor is required. In addition to gear detection, a rotary switch (or potentiometer) should be installed.
Page 115: Gear Scale
Gear scale Gear scale table defines how to scale TC Delta RPM RAW depending on current gear. The lower the gear, the value in the table should also be lower. The value of 100% means no scale of TC Delta RPM RAW. Adjust scale Adjust scale table is used to define how the TC Delta RPM RAW value should be scaled depending on rotary switch / potentiometer position.

EXT. PORT Extension port is used for EMU communication with additional modules like the BlueTooth, CAN- BUS module and racing Dashboards. The extension port is compatible with RS232 serial communication. With the BlueTooth module connected to the extension port it is possible to use an Android application to display gauges on a tablet or phone.
