Free yourself from the constraints of the factory ECU.

We’ve been mapping Link ECUs for a number of years now, with great results.

The Link G4+ ECUs can use a MAP sensor as the primary load input which means the MAF sensor can be removed. This is pretty much essential when wanting to run a top mount turbo. A Link can also run turbo’d throttle body engines, such as the RB26, with sophisticated 4D mapping.

This ECU gives us a large degree of flexibility with a variety of custom definable maps. The ECU can control boost (with gear and TPS boost targets), eradicating the need of a separate boost controller. We can program multiple map options making switching between maps straight forward & seamless. The Link also supports launch control, anti-lag and traction control.

There are a number of safety features available including over boost protection, air temp correction & closed loop fuelling.

We offer the ECU as a standalone product or a package for supply, installation and Mapping.

Below details from Link’s website:

The Link G4+ 350ZLink PlugIn fits the Nissan 350Z with the VQ35DE engine (2002-2006 only. Doesn’t fit the Revup engine or the VQ35HR engine).

Complete with a new enclosure, totally replacing the original unit.

Compatible with:

  • Nissan 350Z
  • Skyline V35
  • Infinity G35 with the VQ35DE engine.

The original ECU is removed, then the G4+ 350ZLink N350+ is installed. The original harness plugs in and the job is done, no wiring required and the original sensors are used.

The G4+ 350ZLink N350+ has an internal 4.0 bar MAP sensor. External MAP sensors are also supported.

Considerable gains in power across the complete RPM range can be achieved with the G4+ 350ZLink N350+ .

The G4+ 350ZLink N350+ allows full control over fuel, ignition timing, and all other engine functions.

The G4+ 350ZLink N350+ is supplied with a base map pre-loaded. Some final tuning will be required.

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.
Factory features are supported – see Features for any exceptions.

The XS Expansion Loom offers the ability to add additional inputs & outputs on our range of plug-in ECUs.
