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.
