Haltech Platinum Sprint 500 (HT050700) - Manual (Page 7)

ECU Manager / ECU Manuals
Detailed manuals can be found in the software by pressing your F1 key or by
selecting the Help tab located at the top left of the screen.
ECU Manager File Extensions
When ECU manager saves the map from the Haltech ECU, it saves the map with
a Haltech specific file extension.
The File extension can be broken down as follows:
Example File : xxxx.hspr05 -106
Later map versions cannot be loaded into ECU's with earlier firmware versions.
ECU Manager will upgrade earlier map versions when loading into ECU's with later
firmware versions.
ECU Manager upgrades maps between versions where equivalent settings are
available. However, new settings not in the original map, will be substituted with
values from the new version's default map.
Whenever ECU Manager converts your ECU map, you should always check your
map settings to ensure that all the appropriate settings have been converted
correctly.
Fuel Pumps
The Black / Yellow wire is used to operate the fuel pump relay. When the Haltech ECU
wants to operate the fuel pump it will close the fuel pump relay which will supply the
fuel pump with 12V From the Battery.
Figure 8- Fuel Pump Wiring
Fuel Pumps continued
It is important that the fuel pump is capable of the correct fuel pressure at full
power, otherwise the engine could be damaged due to a lean fuel mixture. For
example, a 500hp engine requires approximately 210lb/hr for a petrol engine.
The fuel pump must always be mounted lower than the outlet of the fuel tank or
surge tank. Ensure that all care is taken to keep fuel cool. A change in fuel
temperature will change the air/fuel ratio because as fuel temperature increases its
density decreases.
WARNING!
Fuel Injectors
The Platinum Sprint 500 is designed to be used with high impedance injectors only.
Injector impedance can be checked using a multimeter. Injector impedance must be
greater than 8 Ohms, if injectors are used that are less than 8 Ohms, excessive current
draw will cause the ECU to cease firing all injector outputs above 1500 RPM.
Fuel injectors are each wired with a 12V supply with the ground being supplied
through the ECU, it is recommended that the supply for the Injectors be wired as
shown in the appendix of this guide, incorporating an injector relay.
The wires labeled as the injector wires will provide the ground to each injector.
When wiring for sequential injection, fuel injectors should be wired with inj 1 output to
cylinder 1, inj 2 output to cylinder 2 and so on. The injector firing sequence will be set
in the software via the firing order found on the advanced tab of the main setup page.
If semi-sequential injection mode is used the injection sequence will always be inj 1,
Inj 2, inj 3, inj 4 etc regardless of the firing order set in the software.
Always ensure fuel injector sizing is correct for your application and does not
exceed approximately 80% duty cycle for safe operation.
If low impedance injectors are used, an optional Injector Ballast Resistor Box must be
purchased and installed. Order as Haltech Part # HT020600
