The Link G4X XtremeX LS Drive-by-Wire ECU Bundle is the quickest, easiest, cleanest, and most cost-effective way to connect a Link ECU to your drive-by-wire / electronic throttle LS V8 engine. This package combines Link’s premium G4X XtremeX ECU with a terminated GM LS Gen 4 engine harness and LS DBW adapter loom, making it a great solution for high-performance street, track, and motorsport LS builds.
Built around the Link G4X XtremeX, this bundle provides 8 injector drives, 8 ignition drives, built-in electronic throttle control, dual CAN communication, advanced motorsport strategies, and 512MB onboard data logging. The XtremeX supports up to 8-cylinder engines or 4-rotor applications with sequential injection and direct spark, while offering advanced features such as anti-lag, launch control, traction control, cruise control, gear shift control, and closed-loop lambda strategies.

Gen 4 LS Notes
- A cam sensor harness extension is required for Gen 4 LS engines with a front-mounted cam sensor
- A small crank sensor connector modification is required; refer to the crank connector section in the installation manual
- Injector connector adapters to USCAR connectors are required for most Gen 4 engines; confirm your injector connector before ordering
- Use Link PN 101-0287 for USCAR injector connector adapters
- To support Gen 4 factory knock sensors, use the Link LS Gen 4 Knock Adapter Loom, PN 101-0306
- To support the factory Gen 4 MAP sensor, use a Link LS MAP Adapter Loom plus a Gen 3 to Gen 4 MAP sensor extension harness
- A Link MAP sensor may also be used and is directly supported by the harness
Important Notes
- Fuse box and relay are not included
- If a fuse box and relay are required, purchase Link PN 101-0310 separately
- 2 digital inputs are required when using the second CAN bus
- For peak and hold injector applications, contact Link ECU for the correct G4+ Xtreme ECU option
- For onboard digital wideband lambda control, consider the Link G4X Fury ECU
- Professional installation and tuning are strongly recommended
