ADAPTOR OVERVIEW

This adaptor plugs directly into your Haltech Elite ECU and has a set of factory connectors on the other side which plug straight into the factory harness.

A quick and easy plug'n'play upgrade solution.

• 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. 
• The quick start guide will walk you through installation of the Haltech Plug'n'Play adaptor into your vehicle.
• When purchased as a kit with a Haltech ECU, this product is accompanied by the full ECU manual and Software located on the CD or USB key.

ECU FUNCTIONS

• Drive by Wire Throttle Control (DBW) - Requires (2) user defined outputs (4) user defined inputs
• Low Impedance Injector control with Programmable Injector Peak and Hold Currents & Programmable peak time
• Flex Fuel Function (Direct sensor input) - Tune your engines boost, fuel and ignition by ethanol content
• Flexible tuning setup for Petrol (Gasoline), LPG, Methanol and Ethanol allows you to simply select your fuel type
• Closed Loop 02 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 control up to 4 camshafts - Requires a minimum of 1 user defined input & output per variable cam
• Closed Loop Idle Speed Control with 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 & 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 (view live engine data & set and clear diagnostic trouble codes)
• Injection Stages: up to 4 with individual injector flow rates per injector
• 8 Injector drivers for 2 sequential stages on 4 cylinder & 3 rotor engines and up to 4 sequential stages on 2 rotor engines
• Anti-Lag/Rotational idle - for closed course racing, rally, circuit or drift. Build and maintain boost during closed throttle conditions
• Rolling Anti-Lag - lock to your current (or pre-set) RPM or road speed for roll racing or pit lane limiting
• Launch Control - Control your engines power delivery, RPM & boost for consistent performance at the start line
• Traction Control - Control your engines power output via mappable front vs rear axle or individual wheel speed slip.

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

Example 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 9 Channels via CAN expansion devices
• Thermocouples/EGT (Exhaust Gas Temperature) - 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 with advanced programming of up to 6 stages of wet or dry nitrous kits with on/off delays & banked control options.

3D fuel and ignition corrections for all stages.

• Boost Control -Intelligent 4D Closed loop, with learning, flexible user definable axis and 14 fully user definable boost target and duty cycle corrections.

Multiple modes - example boost by gear, road speed, race timer, shock travel, ride height etc.

• Sequential turbo control
• CO2 Boost control, wastegate pressure and position, intake air bleed control (charge pipe wastegate) functionality for the hard-core racer
• Flat shift - Optimise your shifting precision via a combination of inputs such as a clutch switch or strain gauge.
