20A Switched +12V
The 20A Switched +12 volt connection directly
powers the DCMD device. This should come from
a 20A rated fused source such as your vehicle’s
power distribution module.
This connection is pre-terminated within a 4-Pin
DT Connector.
Battery Negative (-)
The Battery Negative is your main ground
connection for the DCMD. This should go directly
to the battery negative terminal or another
suitable ground source.
This connection is pre-terminated within a 4-Pin
DT Connector.
ECU DPOs (Motor Control A/B)
The Digitally Pulsed Outputs from any Elite or
Nexus series ECU can control the DCMD.
Control is Active State: Low
0V on Control A = 0V on Motor A
Pull Up Resistor not required.
Can be controlled from a DPO, Ignition, Injection,
Stepper or DBW ECU output.
Please note that additional programming in NSP
may be required if using devices not directly
supported in the software.
This connection is pre-terminated within a 4-pin
DT Connector.
Motor A
The Motor A connection is supplied by the
2-pin DT connector located on the DCMD. This
connection will drive the rst “channel” or
“motor”. It can supply 8A of power continuously
at a maximum speed of 2.2 kHz.
Motor B
The Motor B connection is supplied by the
2-pin DT connector located on the DCMD. This
connection will drive the second “channel” or
“motor”. It can supply 8A of power continuously
at a maximum speed of 2.2 kHz.

EWG TUNING TIPS
Haltech has designed the Electronic
Wastegate Control strategy to simplify and
speed up the end user’s tuning process.
Existing boost control strategies may be
used with minor adjustments, and the tuning
process should be similar to existing closed
loop boost control systems.
When using an EWG, the “Boost Control
Function” retains its existing Duty Cycle range
of 0% to 100%. Where 100% will request
maximum ow through the turbo and 0%
will request minimum ow through the turbo
(mimicing solenoid based boost control
systems).
However, when using an EWG as your Boost
Control output type, the Boost Control
Function automatically converts boost output
duty cycle into a target wastegate position.
NSP takes into account the different ow
characteristics of the EWG across multiple
valve positions. This means the relationship
between Boost Control output duty cycle and
the Wastegate Flow will be linear.
Tuners should take into consideration the
increased response time of an EWG when
compared to a pneumatic based system. This
may require different approaches to tuning the
Boost Control Function.
Haltech has provided extended tuning tables
for some Boost Control settings, eg Control
Offset, in order to further simplify the tuning
process for different Boost Control scenarios.
At Haltech we make every eort to design and
manufacture fault-free products that perform up to
or above the market expectations. All our products
are covered by a Limited 12 Month Warranty.
Haltech Limited Warranty
Unless specied otherwise, Haltech warrants its products

period of 12 months from the date of purchase.
If the Haltech product is found to be defective as men-
tioned above, it will be replaced or repaired if returned
prepaid along with proof of purchase. Proof of purchase
in the form of a copy of the original purchase invoice,
receipt or bill of sale which indicates that the product is
within the warranty period, must be presented to obtain
warranty service.
Replacement or repair of a defective product shall con-
stitute the sole liability of Haltech. To the extent permitted
by law, the foregoing is exclusive and in lieu of all other
warranties or representations, either expressed or im-
plied, including any implied warranty of merchantability

Product Returns
Please include a copy of the original purchase invoice,
receipt or bill of sale along with the unused, undamaged
product and its original packaging. Any product returned
with missing accessory items or packaging will incur ex-
tra charges to return the item to a re-saleable condition.
All product returns must be sent via a freight method
with adequate tracking, insurance and proof of delivery
services. Haltech will not be held responsible for product
returns lost during transit.
Returns of Products Supplied in Sealed
Packaging
The sale of any sensor or accessory supplied in sealed
packaging is strictly non-refundable if the sealed pack-
aging has been opened or tampered with. This will be
clearly noted on the product packaging. If you do not ac-
cept these terms please return the sensor in its original
unopened packaging within 30 days for a full refund.
A sensor or accessory product may be returned after 30
days of purchase (with its sealed packaging in tact) for
credit only (no refunds given) and will be subject to a 10%
restocking fee.
Installation of Haltech Products
No responsibility whatsoever is accepted by Haltech for
the tment of Haltech Products. The onus is clearly on
the installer to ensure that both their knowledge and the
parts selected are correct for that particular application.
Any damage to parts or consequential damage or costs
resulting from the incorrect installation of Haltech prod-
ucts are totally the responsibility of the installer.
Always disconnect the battery when doing electrical
work on your vehicle. Avoid sparks, open ames or use
of electrical devices near ammable substances. Do not
run the engine with a battery charger connected as this
could damage the ECU and other electrical equipment.
Do not overcharge the battery or reverse the polarity of
the battery or any charging unit. Disconnect the Haltech
ECU from the electrical system whenever doing any
welding on the vehicle by unplugging the wiring harness
connector from the ECU.
After completing the ECU installation, make sure there is
no wiring left un-insulated. Uninsulated wiring can cause
sparks, short circuits and in some cases re. Before at-
tempting to run the engine ensure there are no leaks in
the fuel system.
All fuel system components and wiring should be mount-
ed away from heat sources, shielded if necessary and
well ventilated. Always ensure that you follow work-
shop safety procedures. If you’re working underneath a
jacked-up car, always use safety stands!
