Show original supplier description
The Link ECU G4X XtremeX represents a high-end engine control unit offering advanced features for competitive motorsport and specialized road vehicles. This unit excels with integrated E-throttle, sophisticated anti-lag systems, cruise control, and traction control functionality. Its robust I/O includes 8 high-current injector drives compatible with high impedance injectors and 8 ignition channels, enabling sequential injection and direct spark for engines up to 8 cylinders or 4 rotors. This ECU is packed with extensive adjustment capabilities for both fueling and ignition. Fueling options range from traditional to modeled multi-fuel equations, supporting various injection modes like sequential and staged. Ignition adjustments cover diverse modes including distributor, wasted spark, and direct spark, with up to a 440-zone ignition table for precise tuning. Additional features include multiple limiters based on engine temperature, vehicle speed, and RPM, along with sophisticated launch control, gear shift control, and traction control systems. Installation and operation of the Link G4X XtremeX require specific components. It necessitates "A" & "B" looms or "A" & "B" connector kits, which are sold separately. For digital wideband lambda control, the CANLTW (101-00211) and CANLAM (125-1000) modules are required. All ECUs and tuning services are designated for off-road motorsport use only and should not be used on public roads.
