DISCLAIMER

Haltech will not be held responsible for any damage caused by the incorrect installation or tuning of this
product. It is the installers responsibility to ensure the wiring connections and pinouts match that of the
vehicle the unit is being installed into.

Haltech has taken all care to make sure the connections match the specified vehicles listed, but variations
in wiring and connections on vehicles can occur and therefore this should be checked BEFORE the unit
is installed.

Haltech highly recommends installation and tuning of this product is to be carried out by a professional,
with an understanding on installing and tuning engine management systems.
Misuse of this product can destroy your engine.

WARNING

This ECU is designed and sold for Racing use only. Using this product for street / road use may be
prohibited by law. Please check with your local vehicle authority before using this product.

GENERAL INSTALLATION WARNING

Avoid open sparks, flames or operation of electrical devices near flammable substances.
Always disconnect the battery cables when doing electrical work on your vehicle.

Do not charge the battery with a 24 Volt truck charger or reverse the polarity of the battery
or any charging unit. Do not charge the battery with the engine running as this could
expose the ECU to an unregulated power supply that could destroy the ECU and other
electrical equipment.

All fuel system components and wiring should be mounted away from heat sources,
shielded if necessary and well ventilated. Disconnect the Haltech ECU from the electrical
system whenever doing any arc welding on the vehicle by unplugging the wiring harness
connector from the ECU.

After completing the installation, make sure that there are no fuel leaks, and no wiring
left un-insulated in case a spark or short-circuit occurs and causes a fire. Also make sure
that you follow all proper workshop safety procedures. If you're working underneath
a jacked-up car, always use safety stands!

Haltech Digital Reluctor Adaptor 2

Quick Start Guide

Congratulations on purchasing a Haltech Digital Reluctor Adaptor 2
This product converts the analogue signal from a reluctor sensor into a digital signal
which the engine computer uses to determine the position of the crankshaft and/or
camshaft

This quick start guide will walk you through installation of the Haltech DRA 2 into a
vehicle.

Overview

The Haltech Digital Reluctor Adaptor 2 converts the analog signal from a reluctor
sensor into a digital signal which the engine computer uses to determine the
position of the crankshaft and/or camshaft.

The Digital Reluctor Adaptor has two identical channels, each with a "+" and "-"
input, and one output. The two inputs of each channel are connected to each
wire of the two-wire reluctor sensor, regardless of whether it is connected to the
vehicle's existing engine computer or not.

The output of each channel is connected to an input of the ECU.

There are many kinds of reluctor sensors, so each channel of the digital reluctor
adaptor can be adjusted to best match the signal from the reluctor sensor
connected to it.

There are two blocks of small switches behind the blank end cover plate. One
block for each channel. Only ONE of the first six switches in each block should
be "ON" (down).

Switch 1 (left-hand end) has lowest sensitivity, up to Switch 6 which has highest
sensitivity. A lower sensitivity setting is more resistant to interference from noise
sources such as ignition coils. It is recommended to use the lowest sensitivity
setting while still allowing the Digital Reluctor Adaptor to detect a full signal.

Factory sensitivity setting will be “4”.

Installation Guide

Connect the Pink wire to a +12V Switched Supply
Connect the Black wire to a Chassis Ground

Connect Channel 1 and Channel 2 “+” and “-” Inputs to your reluctor sensors
Connect the corresponding Channel 1 / Channel 2 outputs to the ECU input

Notes

• Channel 1 or 2 paired input wires can be connected to either side of

the reluctor sensor wires as long as the correct trigger edge is selected
within the ECU Manager Software

• If neither reluctor wire is grounded at the sensor, then ground one of them.

It does not matter which one.

• If there is a severe noise problem, then use shielded wire with the shield

connected to ground

Setup Guide

As a guide, reluctor sensors (both Trigger/crank and Home/camshaft) on most

engines will work properly with Switch 4 "ON". However some engines require
different settings. Here's a short list:

Toyota 20v 4AGE engines need Switch 4 "ON" for the Trigger (crankshaft)
sensor, and Switch 3 "ON" for the Home (camshaft) sensor.

Ford AU V8s need Switch 4 "ON" for the Trigger (crankshaft) sensor, and Switch
6 "ON" for the Home (camshaft) sensor
.
Ford Cosworth Sierra Switch 3 “ON for the Trigger (crankshaft) sensor, and
Switch 4 “ON” for the Home (camshaft) sensor.

Some Subarus need Switch 3 "ON" for both the Trigger (crankshaft) sensor and
the Home (camshaft) sensor.

Some MSD distributors have high output and need to have Switch 2 or Switch 1
"ON".

As a guide, you can start out by turning Switch 3 "ON" and see if the engine will
start. If it won't start, turn Switch 3 "OFF" and turn Switch 4 "ON" to increase
sensitivity, and see if it will start then. If the engine computer is still not getting an
output from the Digital Reluctor Adaptor channel during cranking, repeat the
procedure with Switch 5 and even Switch 6 if necessary.

Switch 1 is the lowest sensitivity, Switch 6 is the Highest

Interference / Noise

If you have a problem with severe electrical noise (from ignition coils or
alternators etc) interfering with signals from the reluctor sensors, you can
increase the DRA2's noise filtering.

Remove the end plate opposite the main connector of the case and move
Dipswitch 7 down to the on position.
