Link G4X Plug In ECU - Impreza WRX and STI V11 GR/GV/GH/GE, VAB/VAF (2007-2021)

Now upgraded with Links latest G4X platform, the plugin ECU range has a much faster microprocessor, high speed communications chip and 512 megabytes of data logging across the entire range.

Compared to the older G4+ ECUs, ALL G4X ECUs feature:

A faster Micro controller – meaning your engine will run smoother, accelerate faster and act more responsively

An upgraded Communications Chip –  sees download speeds 16 x faster than G4+

512 Megabytes of data logging – this is over 100x the size of prior Link ECUs

A new version of PC Link tuning software – which is easier to use and modify tunes with

Installation is a breeze with no alteration of the factory wiring loom required. A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag/logging switches.
