Link ECU recently released the G4+ product line which improves upon the standard flagship G4 line. The G4+ line uses different hardware and software but visually appears to be very similar. It is important to understand that a G4 ECU CANNOT be upgraded to a G4+. The Link G4+ Xtreme and Storm will be available first (in a couple months), then the Plug In G4+ line will be available a few months after that. More info will be available soon.
Some of the notable G4+ features that differ from the G4 line:
Labelling of inputs and outputs – e.g. DI 5 can appear as “NOS Switch”
Twenty General Purpose tables (up from twelve) and many dedicated tables
Looping on-board data-logging with selectable parameters and rates – logging can loop continuously
Metric / Imperial display at the push of a button
Built in Trigger Oscilloscope which is displayed within PCLink to ensure optimum accuracy
Memo text file for the tuners notes stored within the ECU
Push Button – engine start / stop – as used on many modern cars
Improved CAN protocol communications
Dealer upgradable features for an additional charge which include: Full Logging (25 channels which can sample at different rates per channel), Internal closed loop Knock Control, Internal closed loop E-Throttle and full OBDII support via the standard OBDII connection.

Complete G4Plus Xtreme Key Features
The following list details why the G4Plus ECUs are so great, but if you talk to someone with a G4 or G4Plus system they love the powerful, smooth total experience :
Super smooth triggering for rock solid ignition timing thanks to the precision automotive microprocessor
Lamda and AFR tuning options – switchable as per user preference
OBD2 data stream by firmware upgrade
Connect up a blue-tooth or wifi adapter (available from your Link dealer, or e-bay etc).
Live data to your phone or tablet for graphical display of the ECUs data
external, 2.5 bar or 5 bar, MAP sensor (sold separately)
optional internal e-throttle upgrade
all G4Plus Storm features
Quick Tune
Using PCLink, QuickTune is an interactive tuning tool that assists in time efficient fuel tuning.
A graphical display of Target lambda (desired lambda) and Actual lambda (measured lambda) is provided. A dual pointer gauge allows the tuner to quickly see how close Actual lambda is to the Target lambda. QuickTune can be setup to operate over the entire fuel table or just over a particular area.
QuickTune can be used in Manual or Automatic modes. In Manual mode, QuickTune guides you to cell centering and advises you when is a suitable time to make a fuel table adjustment. With the press of a key a calculated adjustment is made. Often only one or two adjustments are required to tune each cell. In Automatic mode QuickTune does all the adjustments for you. This leaves the tuner free to operate the Dyno or perform other tuning work such as making ignition or cam angle adjustments.

Up to Six Dimensions of Fuel & Ignition Tuning
Under most circumstances a 3D Fuel Table is sufficient. RPM is typically used for one axis with load (typically represented by TPS or MGP) on another axis. The 3rd axis/dimension is the fuel zone value.
This 3D mapping will be very familiar to the average tuner and a 3D surface representing the fueling can be easily visualised or physically displayed by selecting Surface Graph.
In special cases 3D mapping may not be adequately flexible to cope with all operating parameters.
Multi-throttle turbo charged engines typically show an example of this. With the throttle wide-open at a MAP value of, for example, 200kPa and an engine speed of 5000rpm the engine will have considerably different fueling requirements than with the throttle half open and the same MAP and engine speed. In this case the 4D Fuel Table table may be used. This second table may be spanned using throttle position on the load axis.
When a 4D/5D table is turned on, its Table Activation mode can be selected. This allows the 4D or 5D Fuel Table to become active only under certain conditions. This is useful if an external switch or switching output is required to activate the table (e.g. switching in the 4D Fuel Table when the NOS solenoid becomes active). If the table is required to be always active, set this adjustment to Always ON.
As with all tables, 4D and 5D Fuel Tables can have their X and Y axis parameters selected and their row/column locations adjusted. To do this, click on the table and press X or Y.
These specifications will be updated fully to the G4Plus Storm soon.
