GP Lite

The GP Lite package is an entry-level platform for operating port-injected engines. This single product can be configured to a variety of complexities, from controlling a simple naturally aspirated 4-cylinder engine to a twin-turbo V8. Configurable engine timing modes accommodate most modern engine drive systems.

Included are a number of auxiliary features such as driver switches (engine map, boost limit, etc.), launch control, and single-stage nitrous oxide injection. The GP Lite also supports many systems found on modified road vehicles, such as closed-loop boost control and fuel control, and includes two definable auxiliary control outputs. The package does not include drive-by-wire, variable cam control, or knock control.

It integrates seamlessly with other MoTeC products such as Display Loggers and Shift Light Modules.

Features

Operates 1 to 8 cylinder port injection engines (M130 ECU).
Configurable engine timing modes for many common engine types. See the Engine Speed Modes section for current details.
GP Lite can detect camshaft position on variable cam engines for timing, but does not provide variable cam control.
The TDC setup wizard can be used to set top dead centers 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.
Quick and easy engine tuning using the engine volumetric efficiency map.
Modeling engine load based on intake manifold pressure and intake manifold temperature.
Sensor calibrations available for many common automotive sensors.
Fuel transient compensation using fuel film physics modeling.
Nitrous system with one activation stage with fuel and ignition compensations.
MoTeC Device Support: Shift Light Module, Displays/Loggers
Test settings for most outputs, including injection and ignition outputs, to make setup easier.
Configurable closed-loop turbocharger boost control (using a normal solenoid output).
Coolant fan outlet bracket.
Air conditioning support with switched outlet control.
Coolant temperature compensations for engine speed limit, ignition timing, fuel mixture, boost limit.
Cooling pump output with PWM control.
Coolant pump after-run functionality, optionally with additional pump output.
Engine speed limitation with ignition cut and/or fuel cut with definable interaction.
Fuel pump switched output.
Calculation of engine load temperature, allows correction of inlet air temperature (compensation for heat absorption effect, etc.).
Flame characteristic achieved by delaying ignition timing to allow enrichment and post-fire combustion of exhaust gases.
Closed loop idle control system using ignition and/or idle solenoid.
Idle bypass control with stepper motor supported.
Assisted engine starting with dedicated fuel volume and idle compensation during crank start and post-start.
Configurable security for multiple users.
Preset ECU CAN transmit from available common channels.
Configurable switches to control ignition timing, fuel mixture targeting, boost limit, flame functionality and nitrous injection.
Analog tachometer output with configurable output pin and scale.
Using a throttle position sensor for a cable throttle.
Vehicle speed measurement using rear axle and wheel speed sensors.
Configurable warning system with light output and CAN.
Supports sequential and batch fuel injection.
GPS acquisition and recording via CAN or RS232.
Hard-coded pin inputs to reduce configuration complexity:
- AV1: Throttle position sensor
- AV2: Manifold air pressure sensor
- AV4: Fuel pressure sensor
- AV5: Oil pressure sensor
- AT1: Intake air temperature sensor
