Competition-use certification required

Link ECU engine-management products are sold by Race Club for legitimate competition applications. California and other jurisdictions regulate emissions-affecting aftermarket parts. Street-legal use may require a valid emissions exemption or other approval for the exact vehicle and application.

Race Club may hold, contact the customer about, cancel, or refund an order when the intended use or applicable emissions legality cannot be verified.
Shipping, lead times & import charges

U.S.-stock and overseas-sourced items have different lead times. If this item must ship from Japan or another country, supplier processing, international transit and customs clearance can extend delivery. A shipping service transit estimate does not include supplier lead time. Contact RACECLUB for the current dispatch estimate before ordering time-sensitive or special-order parts.

For shipments crossing a border, customs duties, import taxes and carrier brokerage or handling fees may apply. Charges expressly collected at checkout are shown there; otherwise additional import charges may be payable by the recipient. Foreign manufacture alone does not mean your order will ship internationally. Confirm the shipping origin and any applicable import charges with us before ordering.

Confirm fitment, availability and delivery

Link ECU bundle 109-9020B pairs the G4X XtremeX wire-in ECU with a terminated harness and adapters for supported Gen 4 GM LS2, LS3, LS7 and LSA drive-by-wire engines. Confirm the engine and connector configuration for your installation.

What is included

  • G4X XtremeX ECU, 109-4000, with eight injector and eight ignition drives.
  • GM LS Gen3/4 terminated engine harness, 101-0300.
  • LS drive-by-wire adapter loom, 101-0304.
  • Gen 4 knock adapter loom, 101-0306, and MAP adapter harness, 101-0308.
  • Cam-sensor adapter harness, 101-0307.
  • Eight Bosch male-to-female adapters, 101-0287.

Plan the remaining installation

This package does not include the fuse/relay box. Compare the Gen 4 XtremeX fuse-box bundle, 109-9025B if that is required.

Confirm the throttle body and pedal, crank/cam trigger pattern and connector layout, sensor/injector connectors, chassis power wiring and calibration with your installer. The adapters are not replacement sensors, a throttle body or a pedal. A harness bundle does not establish fitment to every LS-swapped chassis.
