Gen3 LS Drive-By-Wire Bundle: G4X XtremeX ECU + LS Engine Harness bundle

Features

Advanced features of the XtremeX ECU:

• Fully programmable E-throttle control complete with capability of gear shift throttle blip and antilag.
• Cruise control.
• Two independent CAN modules.
• 30 general purpose tables (up from 20).
• All Motorsport features including full gear shift control, cruise control, traction control, antilag and launch control.
• Advanced closed loop lambda strategy and dual bank lambda control.

The terminated harness has the following features:

• Designed to match the PCLink base map I/O configuration, simplifying initial engine setup. Engine-specific settings and wiring assignments must be verified before operation.
• Provides spare I/O via a "Spares" connector, offering extra capacity for sensors, switches, or custom additions.
• Equipped with sealed JPT terminals in the chassis connector (TE Connectivity JPT family), with mating connector specifications provided.
• The harness includes multiple dedicated connectors for key components, such as:
  • Pedal connector (for DBW pedal): 5V, sensor ground, two analog voltage inputs
  • CAN2 connector: for CAN devices like lambda modules, displays, keypads, etc.
  • MAP connector: compatible with Link MAP sensors; the bundle includes an adapter for factory Gen3 LS MAP sensors
  • Knock sensor connector: supports up to two knock sensors; the bundle includes an adapter for factory Gen3 LS knock sensors
  • Alternator connector: for "F Body" alternators; provides exciter/lamp wire to terminal B
  • Transmission ("Trans") connector: for reverse switch, DI, or other functions needing cabin signal
  • IAC connector: for 4-wire stepper IAC; if no IAC is used, those channels may be used for other functions (boost valve, NOS, etc.)
  • TPS connector: for cable-throttle sensors; in DBW applications, this connector may be repurposed
  • DBW (electronic throttle) connector: for DBW throttle bodies, providing analog inputs, 5V and sensor ground

Details

A complete hardware solution for connecting a Link ECU to your Gen 3 (LS1 & LS6) LS V8 engine with electronic throttle (Drive-By-Wire).

The Gen3 LS Drive-By-Wire Bundle (109-9005B) is specifically designed for electronic throttle applications. It combines the G4X XtremeX ECU with a terminated GM LS engine harness, an LS DBW Adapter Loom and dedicated adapters for factory Gen3 LS MAP and knock sensors.

The G4X XtremeX ECU and main engine harness can also support mechanically operated (cable) throttle applications. However, these installations require the appropriate adapter loom and a different ECU configuration. The 109-9005B bundle is supplied specifically for Drive-By-Wire applications.

Bundle Includes:

• G4X XtremeX ECU (8 x Injector and 8 x Ignition Drives) - 109-4000
• Terminated Engine Harness GM LS GEN3/4* - 101-0300
• LS DBW Adapter Loom - 101-0304
• LS MAP Adapter Harness - 101-0302
• LS Gen3 Knock Adapter Loom - 101-0305

If you also require a fuse box and relay, consider the following bundle: 109-9010B.

Gen3 DBW Base Map for G4X XtremeX/StormX

Important Installation Notes

• This bundle is intended for Gen3 LS1/LS6 engines equipped with electronic throttle (Drive-By-Wire).
• The Gen3 DBW Base Map provides a starting configuration and is not a completed or fully calibrated engine tune.
• Engine-specific settings, wiring assignments, throttle body and accelerator pedal compatibility must be checked before operation.
• All required ECU, throttle and pedal calibrations must be completed and verified before starting or operating the engine.
• Cable-throttle installations require the appropriate adapter loom and a different ECU configuration.
