Haltech Platinum Sprint 500 (HT050700) - Manual (Page 9)

Initial Software Setup
Main Setup (Basic) Page
Set the basic engine parameters in the main setup page, number of cylinders,
firing order, load source and map source (enable or disable the use of the internal map sensor)
Trigger Setup Page
Set the crank and cam (trigger and home) angle sensor type and description in the
Trigger setup page. If using a hall effect or optical style crank sensor then set trigger
type to hall effect.
In most stand alone applications the trigger pullup will need to be set to ON when
using a hall effect crank sensor. In a piggy back application the pullup will be set to
off. Trigger pullup will be set to off for all reluctor (sine wave) style trigger inputs.
Ignition Setup Page
Setting the base timing needs to be done with the ignition setup page open. Base
timing is the process of synchronising the ECU’s operations with the engines.
This needs to be calibrated so that the ECU knows the crankshaft position at any point in
time. This is required for accurate fuel delivery and spark timing.
First, go to the fuel setup page and disable the fuel injectors (at this stage it is not
desired that the engine attempts to start). To reduce stress on the starter motor it is also
advisable to remove the spark plugs to help the engine crank more freely when
setting base timing.
Set lock timing to ON and lock timing angle to 10 degrees. Crank engine, using a
timing light connected to ignition lead for number 1 cylinder. Adjust the tooth offset
and trigger angle until timing reads 10 degrees as viewed with a timing light on
crank pulley. Tooth offset gives large changes to timing, trigger angle is used to fine
tune timing to exactly 10 degrees (any angle can be set as the lock timing angle; in
this example 10 degrees was used). It is however possible to set the lock timing to
zero degrees (or any other positive number) and adjust tooth offset and trigger
angle until the crank pulley shows this value when viewed with a timing light.
If there is no RPM being displayed in the software check for correct trigger setup, correct
sensor wiring, correct trigger type, pull ups enabled / disabled, trigger edge falling / rising.
Fuel Setup Page
Set the basic fuel parameters, injection mode, fuel pump prime time and ensure that the fuel
injectors are enabled in this setup page once ignition timing has been checked.
Digital Pulsed Outputs (DPO)
The Platinum Sprint 500 ECU has 4 digital outputs.
The first two outputs are preset to the Tacho and Thermofan functions and the
remaining two outputs are user configurable.
Digital Pulsed outputs are capable of outputting pulsed waveforms with varying duty
and frequency. DPO's can be used to control various devices such as thermo fans,
shift lights, water injection solenoids ,intercooler fans etc.
When a Digital Pulsed output is activated by the ECU the output will switch to ground.
Solenoid valves and shift lights etc can be run directly from the output, however
high current devices such as thermo fans and additional fuel pumps must be activated
through a relay. This way the DPO is only switching a relay and not a high current draw
device.
Digital Pulsed Outputs are limited to 800mA Max current draw.
Digital Pulsed Inputs (DPI)
Digital Pulsed Inputs are capable of accepting pulsed input information such as for a
road speed sensor. These inputs measure the time periods between the pulses and can
process this information to provide quantities such as road speed.
High Tension Leads (spark plug leads) / Capacitive Discharge Ignition Units (CDI )
High tension leads and CDI units can cause significant noise or interference on the ECU
wiring.
Keep all ignition wires a minimum of 100mm from any other wires and ECU
components. If ignition wires must be crossed, ensure wires cross ignition leads at right
angles. Keep power and grounding points separate to those used for ECU.
Wire connections
When using crimp connectors ensure that the correct crimping tool is used – if in
doubt do a pull test on a crimp connector, the wire should break before the wire
pulls out of the crimp. Terminal soldering can weaken a connection and should only
be used as a last resort. If solder joints are used, ensure joints are well isolated
from movement as solder joints are prone to fracture.
When splicing 2 wires it is preferable to use a crimp splice – again if using a solder
joint, ensure joint is limited in its range of possible movement as solder joints are
prone to fracture. Always use heatshrink sleeving to insulate wires and provide
