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

Special order — available to order

This item is ordered from our supplier after you purchase. It is not held in RACECLUB stock. Dispatch depends on supplier availability; contact us before ordering if you need it for a specific event. Shipping transit estimates start after dispatch and do not include supplier processing or backorder time.

Link G4X MonsoonX — 127-4000

A wire-in ECU for naturally aspirated or turbocharged builds, with four injector drives, four ignition drives and six auxiliary outputs. Supports up to four cylinders or two rotors with sequential injection and direct spark.

Features and installation checks

  • VVT, closed-loop boost control, launch control and anti-lag support.
  • CAN bus and 512 MB onboard logging.
  • Not all supported features can run together: the combination depends on the inputs and outputs each feature needs.

Available inputs and outputs limit which features can operate together. Requires an A loom, sold separately. Confirm the required MAP-sensor version before ordering.

Have a qualified installer confirm your wiring, sensors and calibration requirements. Do not use this product in a way that interferes with vehicle safety or emissions-control systems.
