GP Lite

Tab-GP Lite
  • Operates port injected engines from 1 to 8 cylinders (M130 ECU).

  • Configurable engine synchronisation modes for many common engine types. Refer to the Engine Speed Modes section for current details.

  • GP Lite can sense camshaft position on variable cam engines for synchronisation, however it does not provide variable cam control.

  • TDC setup wizard may be used to set the top dead centres on even-fire engines.

  • Configurable ignition output pin for each cylinder allows for coil-on-plug or wasted spark and distributor ignition systems.

  • Dual bank lambda control supported; requires optional LTC with Bosch LSU4.9 sensor or LTCN with NTK sensor.

  • Physical settings for engine displacement, fuel density+molar mass, stoichiometric ratio and injector characteristics, allow for simplified engine start-up prior to tuning.

  • Easy and fast engine tuning using engine volumetric efficiency map.

  • Engine load modelling based on inlet manifold pressure and inlet manifold temperature.

  • Sensor calibrations available for many common automotive sensors.

  • Transient fuelling compensation using physical modelling of fuel film.

  • Nitrous system with one activation stage with fuel and ignition compensations.

  • Support of MoTeC devices: Shift Light Module, Displays/Loggers

  • Test settings for most outputs, including injection and ignition outputs, for easier setup.

  • Configurable turbocharger closed loop boost control (using a normal solenoid output).

  • Support of coolant fan output.

  • Air conditioner support with switched output control.

  • Coolant temperature compensations for engine speed limit, ignition timing, fuel mixture, boost limit.

  • Coolant pump output with PWM control.

  • Coolant pump after-run functionality, optionally with additional pump output.

  • Engine speed limiting with ignition cut and/or fuel cut with definable interaction.

  • Fuel pump switched output.

  • Engine Charge Temperature calculation, allows for correction of Inlet Air Temperature (compensation of heat soak effect etc.).

  • Flame feature achieved by retarding ignition timing to allow enrichment and after-fire combustion of exhaust gas.

  • Idle closed loop control system using ignition and/or idle solenoid.

  • Idle bypass control with stepper motor supported.

  • Assisted engine start with dedicated fuel volume and idle compensations during crank and post start.

  • Configurable security for multiple users.

  • Pre-defined ECU CAN transmit of the available common channels.

  • Configurable switches to control Ignition Timing, Fuel Mixture Aim, Boost Limit, Flame Functionality and Nitrous Injection.

  • Analogue tachometer output with configurable output pin and scaling.

  • Use of a Throttle Position sensor for a cable throttle.

  • Vehicle speed measurement using tail shaft and wheel speed sensors.

  • Configurable warning system with light and CAN output.

  • Hardcoded pin inputs for reduced set up complexity:

    • AV1: Throttle Position Sensor

    • AV2: Manifold Air Pressure Sensor

    • AV4: Fuel Pressure Sensor

    • AV5: Oil Pressure Sensor

    • AT1: Inlet Air Temperature Sensor

    • AT2: Coolant Temperature Sensor

    • Udig1: Reference signal (from crankshaft position)

    • Udig2: Synchronisation signal (eg from camshaft position)

  • 2 auxiliary outputs for PWM control of added actuators:

    • Duty cycle tables using Engine Speed and Throttle or Manifold Pressure Axis

    • Activation based on inlet manifold pressure or vehicle speed

    • Auxiliary Output 1 includes tables for Ignition Timing Compensation and Fuel Volume Trim

  • Optional channels for additional sensors via input pin including:

    • Ambient Pressure

    • Brake Switch

    • Engine Oil Temperature

    • Exhaust Lambda via LTC, LTCN, or PLM for Bank 1 and/or 2

    • Driver interaction switches

    • Exhaust Temperature (EGT) via TCA Thermocouple Amplifier

    • Wheel Speed sensors front/rear left/right.
