Digital Pulsed Outputs (DPO)
The Platinum Sprint RE 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
Startup
Please make sure that you now configure the ECU with the correct fuel, ignition and
trigger settings before going to the main setup menu to calibrate the throttle
Check to ensure that the fuel and ignition maps all have sensible values in them.
Check that all sensors are reading correctly by going to the engine data page and
viewing their values. Ensure the throttle reads smoothly from 0-100% in its full
range of movement. The MAP sensor should read atmospheric pressure
when the engine is stopped.
Power up the fuel pumps and check entire fuel system for leaks before attempting
to start the engine.
Once verified that all sensors are correctly operating and fuel system is functional,
attempt to start the engine. If engine does not start check:
1. Ignition Timing
2. Correct Fuel Pressure
3. Spark Plugs are not fouled or wet
4. Engine Compression
5. Ignition is wired in correct firing order
6. Ignition is firing on intake stroke not exhaust stroke
Once engine is running, ensure fuel pressure remains correct under all conditions and
that battery is charging.
