Haltech Platinum Sprint 500 (HT050700) - Manual (Page 8)

Ignition Outputs
The Platinum Sprint 500 ECU cannot control the ignition coils directly.
Some sort of ignition amplifier such as a power transistor, Haltech ignition module or high
intensity spark unit (CDI unit eg MSD 6A, crane HI6, M&W pro12 etc) must be used
to interface the ECU with the coils. This ignition module supplies the ground to the
coil only when the ECU directs it to – each coil also requires a 12V source (with the
exception of CDI units where the 12V will often come from the CDI unit itself).
Many factory cars will have ignition modules external to the ECU.
These factory modules can be used in conjunction with the Platinum Sprint 500 ECU.
The ignition output wires from the Platinum Sprint 500 wire harness should be used to trigger
the ignition amplifier – when wiring the ignition amplifier ensure that the system is
wired in cylinder order for direct fire ignition setup or in order of the outputs for waste spark
setup. (ie Ign 1 will fire first, then Ign 2 will fire next etc until the last ignition channel is reached
regardless of engine firing order.)

Startup
With the settings now calibrated with correct fuel setup, ignition setup and trigger
setup, go to the Main setup menu and 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.
