bosch dbw throttle(vw-1.8t) possible to connect direct to Emu black.

Yes.

how big current draw can be expected from pin18 and how big from pin13 (which one suply H-bridge, which one is used to measure batt voltage, and which one is suplyiing ecu)

B13 is used for power supply. It could easily provide up to 20A what is more than be drawn from h-bridges.

So pin13 should be fused with 20A fuse and pin18 with 2A ?

And voltage sensing is done from pin13?

So if h-bridge is loaded i can expect some influence on voltage which ecu will see?

Use fuse appropriate for your current draw. If you use DBW 10A will be ok.
If you draw additional current from H-Bridge you need use bigger fuse.

If pin 18 is 0v , is draw from pin 13 less then 10mA ? So i can connect pin 13 directly to batery + only with fuse in stock car with key ignition switch?

can you add a link to the latest firmware versions, maybe in announcements with the other one so we all know where to find it

Hello, i do not understand: What are the main benefits of EMU Black in Relation to the standard EMU? More inputs and outputs? Or something else?

Have you looked into pdf booklet attached in 1.post? There are many improvements compared to EMU.

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 pipe(?)

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)

ANALOGUE INPUTS
EMU BLACK has has two additional analogues inputs in comparison to regular EMU. In addition to this each analogue 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). In comparison to regular EMU 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 (1A for regular EMU). It allows to control stepper motors, electronic throttle, VANOS 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
All AUX outputs of EMU BLACK have built in fly-back circuit for precise control of solenoids (in regular EMU external diodes are required for PWM controlled solenoids).

WBO
Wideband oxygen sensor circuit was redesigned to support LSU 4.2 and LSU 4.9 Bosch sensors.

CAN BUS
EMU BLACK has built in CAN bus support (as well as separate serial communication) with software selectable 120Ohm terminator.

5V OUTPUTS
Regular EMU use the same internal voltage regulator for internal circuits and external sensors (+5V output). EMU BLACK introduces addition +5V regulator for 5V output. In addition to this there are two +5V output terminals for easier harness design.

FIXED 12V
EMU BLACK has new power scheme. The +12V is provided by fixed 12V input (it is used for powering the device and flyback circuit). The switched +12V is used to turn on and off the device.

ANALOG GROUNDS
EMU BLACK introduces 3 separate sensor ground terminals to allow easier harness design.

CONNECTORS
EMU BLACK uses 2 connectors (black and gray). The gray connector (24 ways) has the same pin layout as regular EMU. The black connector is replaced by 39 ways one. Due to smart pin layout it is very easy to repin regular EMU black connector to the new one.

SOFTWARE
EMU BLACK software is improved over the regular EMU. The configuration tree has now additional hierarchy level what makes navigation easier.

Hi!

Is it possible to use chassi ground instead of sensor ground for the switch inputs?

/A

Should work.

[...]

So if i did get it right, with emu black i can drive full seqnetial wasted spark ignition with 12 active coils and half-sequential injection on the V12?

There is not such thing as full sequential WS.
As stated, you can drive 2 active coils from same output, so totally 12 active coils. But in WS, as paired coils are fired same time.

Little correction and addition to this big list
AFAIK all new Blacks should have fly-back on Aux 3-6, while Aux 1-2 are without for injector 7-8.
WBO circuit can now read sensor calibration data directly from sensor.

What is the maximun safe input voltage level for analog inputs, switch inputs and VSS input? Of course with analog inputs it will saturate above 5V.

Switch inputs are activated only by ground.
Analog inputs up to 20V..

VSS/Trigger inputs < 100V

So i can use vss hall sensor which needs 12V power suply and also external pullup ?

Next question i see You have add for each wheel speed. How this will be implement ? Some CAN module ? Stock ABS with CAN ? This will be used only for differential control ?
