The Elite 550 is ideal for basic 4- to 8-cylinder or 1- to 2-rotor engine applications. This rugged, competitively priced ECU is powered by the new Nexus Software Programmer (NSP) – a powerful, intuitive software program that brings a level of functionality and ease of use never before seen in an ECU.
DESCRIPTION
OUTPUTS : up to 4 injectors and 4 ignitions.
COMPATIBILITY : Universal applications 1-8 cylinders or 2 rotors.
INCLUDES : Elite 550 control unit, waterproof USB cap, USB programming cable.
NOTE : Haltech's entry-level, single-plug ECU kit. Ideal for basic 4-cylinder or 2-rotor engine applications and basic EFI conversions.
Overview
Waterproof case (IP67) (with custom USB cover).
34 position AMP connectors.
4 injector outputs (peaks and constants (0-8A peaks/0-2 constants).
4 ignition outputs.
2 inputs for engine position sensors.
A digital broadcast input (supports digital inputs only).
5 digital transmission outputs.
An analog input.
3 x dedicated inputs (throttle position, coolant, air temperature).
A CAN bus for OEM and Haltech CAN expansions.
Internal 4Bar mapping sensor set up to 300kPa pressure (3bar/45psi).
Sequential, semi-sequential, grouped or “multiple” injection schemes.
Distributor ignition system, multiple coil system or Haltech multiplex CDI system.
Load sensing via: Throttle Position (TPS), Manifold Absolute Pressure (MAP) or Mass Air Flow (MAF).
CAN connection to a wide range of dashboards, displays and expansion devices.
Up to 33 channels of input & output (I/O) expansion (via CAN).
USB connection (Windows).
New NSP calibration software.
Control unit functions
O2 Control - Closed loop with long-term correction - for precise regulation (With optional external wideband CAN O2 control kit).
Boost Control - Closed loop with user-definable flexible-axis correction and 6 fully user-definable correction modes - e.g. gear-dependent, speed-dependent engine boost, etc.
Flex Fuel Function (Direct Sensor Input) - Adjusts engine boost, fuel and ignition timing based on ethanol content.
Low impedance injector control with programmable peak and hold currents.
Closed Loop Idle Control - requires 1 or 2 user-defined outputs (BAC type).
On-board and PC data logging - Record data from all available channels directly to your PC's hard drive for both tuning and diagnostics.
Communication to Haltech dashboards and expansion devices via CAN Bus or OBDII (real-time display of engine data & setting and clearing of diagnostic trouble codes).
2 stage injection for use with rotary engines.
The control unit is complete with everything, with no additional cost for the more advanced features.
Advanced adjustment
Adjustment table resolution up to 32x16.
Unlimited tuning flexibility - Engine tuning via a combination of 3D tables with 3D compensations per cylinder and multiple user-definable corrections.
Adjust via a combination of manifold pressure, throttle position, cam position, ethanol content, gear, speed, race time, EGT, damper, ride height or any other channel for maximum flexibility - Dual mapping is a thing of the past.
Cylinder Adjustment Correction - 3D.
O2 Wideband - Connect up to 3 channels via CAN expansion devices.
Thermocouples / EGT (Exhaust Gas Temperature) - Connection of up to 12 channels via external CAN expansion devices.
Variable Cam Control - Independent control of up to 2 camshafts - Requires a minimum of 1 input and 1 output per user-defined variable cam.
