Link G4X XtremeX LS Kit, Drive-by-Wire

An LS swap kit rather than a bare ECU. A G4X XtremeX with a terminated LS engine harness, built for electronic throttle.

We stock it. The harness arrives terminated, with the engine side connectors already fitted, so it is a fit and wire job rather than a build. Check your throttle type before ordering. This is the drive-by-wire kit, which is why it uses the XtremeX: electronic throttle control is programmable on that unit. The StormX kit is the cable throttle one.
