01 / About Sprint 500
About Sprint 500
Platinum Sprint 500 is a compact legacy standalone ECU for naturally aspirated or boosted engines. Four injector and four ignition outputs cover different strategies; the number of cylinders supported is not the same as the number of fully sequential channels.
Rev C: 16 × 16 fuel and ignition tables.
Haltech ECU Manager configuration through USB.
Four high-impedance injector drivers and four ignition outputs.
VE or injection-time tuning with temperature and starting corrections.

Package contents
The actual supplied contents are confirmed in the itemized quote. Check the following items before payment.
Use the quote to check whether the ECU comes with a harness, tuning cable and documents or is supplied alone.
04 / Fitment & installation: Haltech Sprint 500 ECU
Fitment & installation: Haltech Sprint 500 ECU
Check the model, hardware revision and connector pins against the device’s wiring diagram.
Use the exact ECU wiring diagram; verify every circuit for continuity and shorts before connecting power.
Use ECU Manager and the pinout for the corresponding older Platinum model; do not apply current Nexus or Elite wiring documents.
05 / Questions about Sprint 500
Questions about Sprint 500
Can Sprint 500 drive low-impedance injectors directly?
No. Sprint 500 supports high-impedance injectors above 8 Ω. Low-impedance injectors need a separately matched driver arrangement.
Does eight-cylinder support mean eight sequential outputs?
No. There are four injector and four ignition outputs. Cylinder count must be matched to batch, semi-sequential, distributor or wasted-spark arrangements.
Which software and computer connection does Sprint 500 use?
Sprint 500 connects to ECU Manager via USB. Install Platinum software and drivers; Elite and Nexus packages are not for this platform.
What tuning tables are listed for Sprint 500?
Rev C has 16 × 16 programmable tables, describing load and RPM breakpoints. Table size is not a power rating; calibrate for the actual engine.
Can Sprint 500 use a VE fuel model?
Yes. Select either VE or injection-time modelling in ECU Manager. VE still requires correct injector, fuel and sensor data; changing the model does not make the old table values suitable.
Do the two Sprint 500 generic outputs include every fixed output?
No. In addition to the two programmable outputs, there are fixed functions for the fuel pump, fan and tachometer. Check each pin, load and current when wiring, and do not assign the same pin more than once.
Can Sprint 500 read a bare LSU wideband sensor directly?
No. An LSU sensor needs an external wideband controller. Sprint 500 reads that controller’s measurement output using the matching calibration curve; its O2 input cannot drive the LSU heater or pump cell.
Which fuel corrections are available beyond the base map?
The Rev C sheet lists temperature, barometric, injector-dead-time, post-start, priming and throttle-related corrections. Configure these with the base fuel model to address cold starts, temperature changes and transient operation.
Can a password-protected Sprint 500 tune always be edited?
Calibrations can be password-protected. Confirm access and back up before hardware or software changes; USB connection does not unlock a protected map.
Does the Sprint 500 legacy OS list guarantee Windows 11 compatibility?
Not automatically. Legacy software lists Windows 2000 / XP / Vista / 7; modern 64-bit systems need ECU Manager and USB-driver compatibility checks and a communication test.
