The XtremeX is one of Link’s premium ECU’s with more inputs, outputs and features.

The XtremeX has built in E-throttle and all the advanced features including Anti-lag, Cruise Control and Traction Control.

With 8 Injector drives and 8 ignition drives the XtremeX can control up to 4 rotors or 8 cylinders with sequential injection and direct spark. The XtremeX is a great choice for professional level motorsport or more demanding road car applications.

Please note: for peak & hold please contact a Link ECU Sales Person to purchase a G4+ Xtreme ECU.
Requires “A” & “B” Looms for installation.
If it is Onboard Digital Wideband Lambda Control you are after, consider the Fury.
