Important Notes

Auxiliary Output Channels 13-16

These are high current Half bridge drivers which switch either to ground or 14V i.e. they do not have a high impedance or OFF state. When the ECU is powered OFF these Auxiliary Channels by default will be switching to ground. This means:

  1. Solenoids or relays connected to these outputs should not use a constant or hot battery feed.
  2. During the ECU powerup sequence, any solenoid or relay connected to these outputs should have a managed power feed to avoid momentary switching during powerup.

Analog Sensor 0V Reference (Pin C17, C25)

These pins should be connected directly to the 0V (Ground) pin on any low current analog sensor, for example Pressure or Temperature.

  • DO NOT connect the ECU pins C17, C25 directly to the Engine Block or ECU Ground. These are dedicated and specialised ground outputs for all analog channels and should be connected directly to the sensor.
  • DO NOT connect frequency-based sensors to these pins; for example, an Ethanol content sensor. The sensor 0V pin should be connected to the ECU ground.

Half Bridge Driver Power Supply Inputs (Pin D20, D2)

Pin D20 is a dedicated power supply for Auxiliary Channels 9-12. Power must be supplied to this pin for these channels to operate correctly. In non-DBW (Drive by Wire) applications the ECU Supply power can be shared, assuming the wire gauge has a sufficient rating for the current demand. In DBW applications power to this pin MUST come from an ECU controlled DBW Relay.

Pin D2 is a dedicated power supply for Auxiliary Channels 13-16. Power must be supplied to this pin for these Auxiliary channels to operate correctly.

Important Notes

Auxiliary Output Channels 13-16

These are high current Half bridge drivers which switch either to ground or 14V i.e. they do not have a high impedance or OFF state. When the ECU is powered OFF these Auxiliary Channels by default will be switching to ground. This means:

  1. Solenoids or relays connected to these outputs should not use a constant or hot battery feed.
  2. During the ECU powerup sequence, any solenoid or relay connected to these outputs should have a managed power feed to avoid momentary switching during powerup.

Constant 14V Supply/Backup (Pin C53)

This pin has two features:

1) Flywheeling for Auxiliary Channels 1-8.  Any Inductive energy will be sent to the “Constant 14V Supply” pin. To minimise any EMI and allow solenoid current recirculation to operate correctly this pin should be connected to a constant power supply.  If this pin is left unconnected the back EMF will be clamped at 45V.

2) Internal ECU EFI Relay function.  When power is removed from pins " ECU 14V Supply" the ECU automatically switches to the “Constant 14V Supply” to keep the ECU powered.   This will allow the ECU to complete critical tasks before shutting itself down (for example, DBW Self calibration and ECU Logging data storage).

To enable this function, set the EFI Relay Control Channel to “Internal EFI Relay Ctrl”

NOTE: With a Constant 14V supply wired, the ECU draws no additional current when OFF.

Analog Sensor 0V Reference (Pin C28, C29, C30, C31)

As the name indicates these should be connected directly to the 0V (Ground) pin on any low current analog sensor, for example Pressure or Temperature.

  • DO NOT connect these pins directly to the Engine Block or ECU Ground. These are dedicated and specialised ground outputs for all analog channels and should be connected directly to the sensor.
  • DO NOT connect frequency-based sensors to this ground; for example, an Ethanol content sensor. Use either the Digital Input Ground Out pin (A31) or the main ECU ground.

Important Notes

Analog Sensor 0V Reference (Pin B10)

This pin should be connected directly to the 0V (Ground) pin on any low current analog sensor, for example Pressure or Temperature.

  • DO NOT connect the ECU pin B10 directly to the Engine Block or ECU Ground. These are dedicated and specialised ground outputs for all analog channels and should be connected directly to the sensor.
  • DO NOT connect frequency-based sensors to these pins; for example, an Ethanol content sensor. The sensor 0V pin should be connected to the ECU ground.

Half Bridge Driver Power Supply Input (Pin A34)

Pin A34 is a dedicated power supply for Auxiliary Channels 9-10. Power must be supplied to this pin for these channels to operate correctly. In non-DBW (Drive by Wire) applications the ECU Supply power can be shared, assuming the wire gauge has a sufficient rating for the current demand. In DBW applications power to this pin MUST come from an ECU controlled DBW Relay.

Shadow 8 Power Distribution Wiring

Shadow Power Supply System

The Shadow 8 power supply system has been designed to allow flexibility on how the ECU manages power-up and power-down sequencing.

The real advantage is on the power-down sequence, allowing the ECU to power-down once all pending tasks have been completed. This effectively acts as an internal Hold Power System.

ECU Supply (Pin A1)

Pin A1 is the main power supply into the ECU .

Battery Constant Supply (Pin B1)

ImportantPin B1 is a permanent power supply and should ALWAYS be connected to a constant 12V supply.

ALL Auxiliary flywheel control is directed to the pin; therefore, this pin MUST always have power connected.

Note: The ECU draws zero current once completely shut down.

Aux 9-12 (Half Bridge) Driver Power Supply (Pin B26)

Pin B26 is a dedicated power supply for Auxiliary Channels 9-12. Power must be supplied to this pin for these channels to operate correctly.

In non-DBW (Drive by Wire) applications the ECU Supply can be shared, assuming the wire gauge has a sufficient rating for the current demand.

ImportantIn DBW applications power to this pin MUST come from an ECU controlled DBW Relay.

ECU Power Supply Wiring

The ECU power supply can be configured in one of two ways; both options assume constant power is fed to pin B1.

OPTION A – Power Supply Pin Controlled

This is the main option for ECU Power Supply control.

Power-On

Power to the ECU Supply pin A1 can be switched ON using a PDM or from an Ignition switch controlled relay. When the ECU detects power on this pin, it will power up.

Power-Off

When the ECU Supply falls below 6.0V the ECU enters a Shutdown Sequence and uses the Constant Supply to remain ON during this process.

The ECU uses the time value from the “EFI Relay OFF table” to determine Power-down. However, the following tasks will prevent an ECU power-down:

  • ECU CAL file Store in progress
  • ECU Datalogging Store in progress
  • Emtune connected. (Emtune must be disconnected for the ECU to power-down)

Once the ECU has completed all shut down tasks, and the EFI Relay OFF Delay time has elapsed, the ECU will power-down.

ECU Settings

The following settings must be configured for this mode to operate.

  1. Ignition Switch Source Input selected to OFF Image Image

  2. EFI Relay OFF Time Image Image

OPTION B – Ignition Switch Pin Controlled

This mode should only be used when the ECU needs to control an external EFI Relay, normally in OEM applications.

Power-On

This option uses the Ignition Switch Input, shared with DI10(Pin B21) to power-up the ECU.

When Ignition Switch Input Pin B21 is > 6.0V, the internal circuity will turn the ECU ON using the Battery Constant supply.

Once powered on, the ECU can switch/control an external OEM EFI relay using one of the ECU outputs.

For example, Aux 8 could be configured as a High Side Output, suppling power to a relay coil and turning it ON, which in turn supplies power to the ECU Pin A1.

Power-Off

When the Ignition Switch falls below 6.0V the ECU enters the Shutdown Sequence. The same shutdown conditions apply as outlined in Option A.

ECU Settings

The following settings must be configured for this mode to operate.

  1. Ignition Switch Source Input selected to Dedicated – Ign -Sw. In this case this input is shared with DI10. Image Image

  2. EFI Relay OFF Time Image Image

IMPORTANT NOTE

Regardless of the ECU’s settings, a high input on DI10 will cause the ECU to power up. Care should be taken to not unintentionally supply power to this pin.

Power Supply Wiring

EFI Relay Control

All Emtron ECU systems can control an EFI relay, allowing for management of its own power supply. To achieve this a dedicated Ignition Switch input and dedicated EFI Relay output are used. When 12V is applied to the Ignition Switch input, the ECUs fixed internal circuity switches the EFI Relay output to ground. This can be used to turn ON the Main relay and supply power to the ECU and sub systems. This functionality is controlled at a hardware level, meaning 12V at the Ignition Switch input will ALWAYS make the EFI Relay output turn ON and switch to ground.

Once powered up the ECU takes control of the EFI Relay output, operating independent of the Ignition Switch input. When the Ignition Switch input goes low (turns OFF) this triggers the ECU to enter shutdown mode, but the ECU will only switch the Main relay OFF after all critical self checks have been completed

WarningIt is highly recommended the EFI Relay system be used!

By allowing the ECU to control its power supply, when the Ignition Switch input turns OFF the ECU can firstly complete critical tasks before shutting itself down (for example, DBW Self calibration and ECU Logging data storage).

The below image shows the internal operation of the EFI Relay system. The control on the EFI Relay output (Low side driver) is managed by a diode OR gate i.e if the Ignition Switch input is ON OR the ECU Control is ON, the EFI Relay output will be ON and providing a ground.

Power Supply Input

The Emtron ECU system has a main power input to run the ECU (ECU supply pin), but also has the capability to distribute power through various outputs as well. The following power supply pins must be fed 12V in order for the ECU to distribute them to the following outputs (as high side outputs).

SL Series ECU

  • Aux 5-8 ECU Supply Pin B1. As well as the main ECU supply, it also provides power to the Aux 5-8 High Side Drivers.
  • Aux 9-10 Power Supply Pin A34. Supplies power to Aux 9/10 Half bridge drivers.

KV Series ECU

  • Aux 1-8 ECU Supply Pin D1. As well as the main ECU supply, it also provides power to the Aux 1-8 High Side Drivers.
  • Aux 9-12 Power Supply Pin D20. Supplies power to Aux 9/12 Half bridge drivers.
  • Aux 13-16 Power Supply Input D2. Supplies power to Aux 13/16 Half bridge drivers.

H-Bridge control

Selected outputs can supply either a ground or battery voltage i.e. there is no “off” state, called Half-bridge outputs. Combine two half bridges and this forms an H-bridge configuration.Since the most common use for this type of output is Drive by Wire (DBW), it is necessary to control the supply power to these supply pins via a separate circuit so that the ECU can control this individually (E-throttle Relay Circuit).

This will allow the ECU to disconnect power to that distribution source in the event of an error being detected, but still maintain functionality of the engine, store fault codes, record logs, etc. Most DBW cars will default mechanical throttle position to a “raised” idle, and an extra level of Limp Mode will also function to cut RPM in the event of unintended mechanical acceleration.

SL Series ECU

  • H-bridge control for Aux 9-10 (1 pair).

KV8/12 ECU

  • H-bridge control for Aux 9-10 / Aux 11-12 (2 pair).

KV16/16M ECU

  • H-bridge control for Aux 9-10 / Aux 11-12 / Aux 13-14 / Aux 15-16 (4 pair).

Grounds

Main ECU Grounds

All Emtron grounds are internally linked, however each ECU major section/plug has dedicated grounds. Most ECU functions in general distribute ground connection to operate components (fuel injectors, relays, boost solenoids, etc). Do NOT try to use one single ground since they are all linked. Pay mind to the fact that all of these outputs need to make complete circuits to ground when being activated, and the current limit of each ECU pin is only 12 amps.

Sensor 0V Reference Grounds

These pins are NOT ECU grounds. Although a multi-meter test will show continuity to the ECU ground, these pins are designed as a low current 0V reference for pressure, position and temperature sensors. The following rules MUST always be observed:

WarningDO NOT connect these pins to the ECU main ground location(s)!

This is a specialized ground reference for all analog sensors and should be connected directly to the sensor 0V(ground) pin.

WarningDO NOT connect frequency-based sensor grounds to the 0V Reference pin.

For example: an Ethanol content sensor. Use the main ECU ground.

Differential Input Grounds

Inputs with +/- (Crank, Sync, Knock) are considered Differential Inputs. These “-” pins are used for as a comparator for the input pin, and are NOT linked to ECU grounds or Sensor 0V Reference grounds (regardless of tested continuity). This is also the reason pulsed signals are safe to be connected to these pins. When wiring these inputs, it is highly recommended to use them without fail, as like the 0V reference for analog volt sensors, the differential input will behave appropriately during all electrical situations such as when voltage drop can be high during cranking, etc.
