Link G4+ PlugIn ECU's provide a straight forward way to gain full control over your engine functions while still keeping the stock appearance of the original ECU case.
The original motherboard and connector are removed from the ECU case and the Link motherboard and connector screws into the case. Remove the stock AFM, and install an IAT sensor in it's place. Wiring info will be provided. The original harness plugs in and all original sensors are used (except for AFM, and who wants to use that anyway?).
External view of ECU case and connector is unchanged from its stock appearance.
External 4 bar plug-in map sensor that requires no wiring is available, and many different aftermarket MAP sensors can be used, or just use the stock map sensor
Considerable gains in power across the complete RPM range can be achieved with these boards.
Allows full control over fuel, ignition timing, boost pressure and all other engine functions. All boards have QuickTune software and optional Anti-lag.
All boards are supplied with an ATS Basemap. Final tuning will be required.
GM Flex Fuel sensor support for E85
4-pin ignition expansion connector for Direct Ignition (Coil On Plug)
The Link G4+ PNP ECU is very capable with control of up to four variable cams and support for engines up to twelve cylinders. Software has very flexible options over how the inputs and outputs are controlled, and allows the user to design their own functions to control all sorts of devices. Precise control of injectors and ignition angle are guaranteed at very low or high RPM or manifold pressures. A very high level of protection from interference and tolerance of trigger input errors has been built into this ECU, ensuring a smooth running engine even under the most demanding conditions.
Motor Sport features include: Antilag, Flatshift, Launch control.
Individual Cylinder Knock control, when external digital knock amplifier used (available separately).
Peak and hold injector drivers. Both the peak Amps and hold Amps can be set separately in the software for optimum injector control.
Closed loop control of idle speed and boost pressure makes for a "factory" idle speed stability, and precise control of boost pressure. Boost control can be setup to provide a different boost in each gear or switch between boost control tables.
