All ECUs are supplied with a set of connectors and terminals
The EMU-BLACK is a class-leading, stand-alone engine management system, designed to operate the most advanced and complex engines presently available. It is a successor of our proven system, EMU- Classic. During the EMU lifetime vast amounts of data has been collected and used to upgrade the device hardware and software.
EMU Black targets race cars, road cars, motorcycles, and boats. The EMU Black controls fueling, ignition and auxiliary systems on 1-12 cylinder engines including directly controlling those with drive-by-wire throttles VVT and CAN-BUS communications. It can drive up to 6 passive or 12 smart coils directly and does not require external igniter modules.
Supports up to 8cyl full sequential injection. Sophisticated drive-by-wire strategies provide a wide range of throttle control along with advanced plausibility (fault/error) checking for safety. The system capabilities continually increase over the time due to easily-upgradable, free of charge firmware (eg. new strategies, trigger patterns, CAN data streams)
UPGRADED features from EMU CLASSIC
ENCLOSURE
EMU BLACK bespoke enclosure is made from CNC machined aluminium. The enclosure
design guarantee high immunity to mechanical damage, water resist (IP65) and very good
heat conduction from electronic components.
Additional hole through the enclosure provides mounting point.
At the front of the enclosure there is a micro usb sealed connector for PC communication
and MAP sensor connection
PCB
EMU BLACK utilize 4 layers PCB board and most of components are SMD type (except
connectors) and coated with special surface protecting the board and components from
moist. Due to design, the device is extremely immune to the vibration.
Device is assembled according to IPC-S-815A standards on fully automated assembly line
with optical inspection to ensure highest possible quality.
Carefully electronic components selection allows proper device operation in very wide
temperature range (-40C to 105C) (AECQ-100 GRADE2)
ANALOG INPUTS
EMU BLACK has has two additional analog inputs in comparison to regular EMU. Total: 12 (6 AUX, 3 switch, 3 dedicated)
addition to this each analog input has software selectable pullup / pulldown (4700Ohm).
For CLT and IAT inputs the pullup resistor is 2200Ohm and could be disabled via software.
That allows easy sharing temperature signals with OEM ECU when connected in parallel.
SWITCH INPUTS
EMU BLACK introduces 3 digital switch inputs that could be used for activating strategies by switching input to the sensor ground.
TRIGGER INPUTS
The input circuit for trigger inputs was redesigned. For each trigger input (Primary trigger,
CAM#1, CAM#2 and VSS) pullup / pulldown could be selected (4700Ohm, 1000Ohm,
820Ohm) as well as analogue filter level (none, low, medium hall).
Primary trigger input could be HALL or VR (software selectable). For VR sensor the adaptive
level could be changed (low, high).
For CAM#1 and CAM#2 inputs the reference voltage could be defined in separate 2D tables
in function of RPM what greatly improves noise immunity for VR sensors (the higher RPM
the higher trigger voltage threshold)
For VSS sensor VR or HALL sensor type could be selected.
FLEX FUEL INPUT
EMU BLACK introduces separate input for Flex Fuel sensor ( regular EMU uses CAM#2 or VSS input for this purpose).
IGNITION OUTPUTS
Ignition output circuit was redesigned especially the driver of active coils.
EMU BLACK
supports active and passive coils (software selectable) It is possible to drive 2 active coils from one ignition output. In addition to this when active coils are selected for connected passive coils no damage occurs.
H-BRIDGE
The stepper outputs of regular EMU were replaced by two state of the art bullet proof H-BRIDGEs with over 6A continuous current (3A for regular EMU). It allows to control stepper motors, electronic throttle, VVT as well as any solenoid with current draw lower than 6A (low and high side drive possible)
DBW
Due to high current capability of built in H-BRIDGE, EMU BLACK is able to control directly
electronic throttle (no external module required). Moreover the control strategy was
improved (two times higher update rate, defined PWM frequency from 1000Hz to 8000Hz)
to allow higher precision of throttle control. For safety reason the DBW strategy works on 2
separate processors and any malfunctioning in one of them causes throttle limp mode.
AUX OUTPUTS
Total 6 AUX outputs of EMU BLACK have built in fly-back circuit for precise control of solenoids. Unused injector and ignition OP's can also be used for Aux OP functions.
(in regular EMU external diodes are required for PWM controlled solenoids).
