ECU Overview The Elite 2500 ECU is a two-connector, stand-alone unit ideal for late-model performance and racing applications. It supports various engine configurations and provides advanced features for optimal tuning and performance. Supports: 1 to 12 Cylinder engines, 2 to 4 Rotor engines, normally aspirated or forced induction. Load Sensing: Throttle Position (TPS), Manifold Absolute Pressure (MAP), or Mass Air Flow (MAF). Connections: Compatible with a wide range of display dashes and expansion devices via CAN. Inputs/Outputs: 8 Fuel Injection Outputs, 8 Ignition Outputs, 12 Digital Outputs, 10 Analogue Voltage Inputs, 4 Synchronised Pulsed Inputs, 4 Dedicated inputs (Dual Knock, Ignition Switch & Onboard MAP Sensor), 2 Dedicated Engine Position Inputs with extensive trigger type support, up to 45 channels of I/O expansion via CAN, and USB Laptop communication. ECU Functions Drive by Wire Throttle Control (DBW): Requires (2) user-defined outputs and (4) user-defined inputs. Injector Control: Low Impedance Injector control with programmable peak and hold currents and peak time. Flex Fuel Function: Direct sensor input for tuning engines' boost, fuel, and ignition by ethanol content. Flexible Tuning Setup: Suitable for Petrol (Gasoline), LPG, Methanol, and Ethanol. Closed Loop O2 Control: Dual bank control for precise tuning (with optional external CAN O2 Wideband Controller Kit). Dual Channel Knock Control: Synchronised to engine position with high-speed digital filtering for accurate detection. Variable Cam Control: Independently controls up to 4 camshafts, requiring a minimum of 1 user-defined input and output per variable cam. Closed Loop Idle Speed Control: Learning for consistent idle stability, requires 1 or 2 user-defined outputs (BAC type) or 4 user-defined outputs (Stepper motor type). Long Term Learning (Auto Tune): On fuel, ignition, cam, boost, and idle control maps (up to 4D). On-board Data Logging: Up to 40 channels of logging at sample rates up to 5ms (200Hz) with 2MB of internal memory. Laptop Data Logging: Data log all available channels directly to your laptop's hard drive for both tuning and diagnostics. Dual CAN Bus Communication: For Haltech dashes and expansion devices, supported OEM CAN & OBDII. Advanced Tuning Tuning Table Resolution: Up to 32 x 32 x 8. Limitless Tuning Flexibility: Tune your engine by a combination of 4D tuning tables combined with 3D per cylinder compensations and multiple user-definable corrections. Per Cylinder Tuning Correction: 3D. Wideband O2: Connect up to 9 Channels via CAN expansion devices. Thermocouples/EGT: Connect up to 12 Channels via external CAN expansion devices. Engine Protection: Set advanced multi-level limits for sensors and protect your engine against common causes of failure. Race Functions Nitrous Control: Advanced programming of up to 6 stages of wet or dry nitrous kits with on/off delays and banked control options. Boost Control: Intelligent 4D Closed loop, with learning, flexible user-definable axis, and 14 fully user-definable boost target and duty cycle corrections. Sequential Turbo Control. CO2 Boost Control: Wastegate pressure and position, intake air bleed control (charge pipe wastegate) functionality for the hardcore racer. Flat Shift: Optimise shifting precision via a combination of inputs such as a clutch switch or strain gauge. Shock Travel/Ride Height Inputs: Allow dynamic tuning and data logging to assist in chassis development and power delivery. Timer Functions: Use the combination of the race timer and 5 additional programmable timers for time-based control of multiple engine parameters, power delivery, and other user-definable functions. Trans Brake Function: Allows smooth and consistent control of start line staging (Bump or Creep). Optional Upgrade - Advanced Torque Management: A fully integrated driveshaft RPM target race function that provides the ultimate control and consistency for the serious drag racer, eliminating the need for costly external controllers.
