Description
Haltech offer a range of pre-build wiring harness options along with harness adapters.
The Elite 550 is the smallest ECU HAltech offer. it is a great option for those working on a budget or building a new EFI system on an older car such as an RX-7 FB converted to EFI or anything else with low limited requirements. The Elite 550 offers a limited range of features for example it does not offer knock control or drive by wire.
Due to its size you will need to be selective with what sensors and features you with to use, as on the smaller Elite series ECU’s Inputs and Outputs are limited.
With any wire in ECU we would recommend doing your own research to determine that this ECU will work for your application and offer you the features and functionality that you are looking for.
Outputs: Up to 4 injector and 4 ignition.
Suits: Universal 1-8 cylinder or 2 rotor applications.
Includes: Elite 550 ECU, Premium universal wire-in harness. firewall grommet, moulded 6 power circuit Haltech fuse box and lid. 2 relays, 4 fuses and pins for the 4 spare power circuits. Waterproof USB cap, USB programming cable and software CD.
Notes: Haltech’s entry level, single connector ECU Kit. Ideal for basic 4 cylinder or 2 rotor engine applications and basic EFI conversions.
- Colour coded and labelled wires that match the detailed wiring diagram for a confusion free construction process.
- The wiring diagram is accompanied by the full ECU manual and Software located on the CD or USB key provided with the ECU to refer to while completing your installation and configuration.

- Now using the new NSP Calibration Software
- This harness when installed in conjunction with a Haltech Elite ECU opens the door to virtually limitless performance modification and tuning of your vehicle.
- Fully programmable systems allow you to extract all the performance from your engine by delivering precisely the required amount of fuel and ignition timing that your engine requires for maximum output under all operating conditions.
ELITE 550 Features
- O2 Control – Closed Loop with Long Term Learning – for precise tuning (With optional external CAN O2 Wideband Controller Kit).
- Boost Control – Closed loop with learning with flexible user-definable axis and 6 fully user-definable corrections modes – for example, boost by gear, road speed etc.
- Flex Fuel Function (Direct sensor input) – Tune your engine’s boost, fuel and ignition by ethanol content
- Low Impedance Injector control with Programmable Injector Peak and Hold Currents
- Closed Loop Idle Speed Control – requires 1 or 2 user-defined outputs (BAC type)
- On-board and Laptop data logging – Data log all available channels directly to your laptop’s hard drive for both tuning and diagnostics
- CAN Bus communication for Haltech Dashes and expansion devices or OBDII (view live engine data and set and clear diagnostic trouble codes)
- 2 Injection Stages for use with Rotary Engines
- ECU comes fully enabled, with no additional charges for advanced features.
- Tuning Table Resolution up to 32 x 16
- Limitless tuning flexibility -Tune your engine by a combination of 3D tuning tables combined with 3D per cylinder compensations and multiple user-definable corrections
- Tune by a combination of manifold pressure, throttle position, cam position, ethanol content, gear, road speed, race time, EGT, shock travel, ride height or any channel for ultimate flexibility – Dual mapping is a thing of the past.
- Per Cylinder Tuning Correction – 3D
- Wideband O2 – Connect up to 3 Channels via CAN expansion devices
- Thermocouples / EGT (Exhaust Gas Temperature) – Connect up to 12 Channels via external CAN expansion devices
- Variable cam control – Independently control up to 2 camshafts – Requires a minimum of 1 user-defined input and output per variable cam
PLEASE NOTE THAT DUE TO THE LIMITATIONS IN INPUTS AND OUTPUTS WE CANNOT GUARANTEE THAT THIS ECU WILL WORK WITH YOUR APPLICATION IN THE WAY YOU WISH,
We recommend you ensure you are selecting the proper ecu to serve your requirements, if you are not sure then we would recommend looking as the next size up of ecu to see if this fits your bill.
While these smaller ECU’s can be made to work on more basic installs and there are a large list of features, it is important to remember that you may not be able to use them all. you will need to be selective with what you need.
