Is a Plug-In ECU right for me?

The Link G4X Plug-In ECUs take the headache out of custom wiring a standalone ECU. It provides a neat and tidy solution to fitting a programmable ECU to your vehicle and offers all of the same processing power as the top of the line Xtreme ECU. The Link G4X Plug-In ECU allows factory inputs and outputs to be reconfigured to perform other tasks, or simply add an Link XS connector to provide additional inputs if required.

In most cases where a Link G4X Plug-In ECU is available for your particular model of car, this is the best option. If you have any queries feel free to contact our friendly team for further advice.


Simple to install

Wiring in a standalone ECU is time consuming and requires a good knowledge of automotive wiring for a successful result. The Link G4X Plug-In ECU makes it quick and easy. Installation is as simple as fitting the new Link G4X Plug-In ECU board to your factory ECU enclosure and plugging in the factory loom.

No wiring is necessary, and if your car is standard then the ECU will allow you to startup and drive your car straight away!*

* Startup map is intended to allow vehicle to be transported to a dyno facility only. All G4X ECUs should be tuned specifically to suit each individual installation.

Total control means more power, better fuel economy and perfect driveability

The Link G4X Plug-In ECU utilises the same processor as the top of the line Xtreme. The advanced processing power provides unparalleled accuracy and control. Coupled with Link’s user friendly PCLink tuning software, getting the best out of any engine is easily achievable – You won’t be disappointed!

Gone are the days where having an aftermarket ECU meant that you had to suffer with poor cold start performance and a car that no longer idles properly. The Link G4X Plug-In ECU offers complete control of cold start performance and can control your stock idle speed system. Correctly tuned, this means your car will cold start and idle just as well as it did from the factory.*

*Engine must be fitted with factory idle speed system. Heavily modified engines with large camshafts may  not be able to achieve stock-like idle.


Works with your factory sensors – No expensive extras required

The Link G4X Plug-In ECU is configured to use your factory sensors. This saves you the cost of additional sensors just to make your engine run. With the flexibility of the Link G4X Plug-In ECU, you can still choose to change any factory sensors or add your own if you want. Just adjust the calibration and you are ready to go.
