Quick Tune
Using PCLink, QuickTune is an interactive tuning tool that assists in time efficient fuel tuning.
A graphical display of Target AFR (desired AFR) and Actual AFR (measured AFR) is provided. A dual pointer gauge allows the tuner to quickly see how close Actual AFR is to the Target AFR. 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.
Peak and Hold
The G4 Xtreme has eight channels of independently configurable, peak and hold fuel injection control.
With high impedance injectors it is possible to apply the full battery voltage (saturation) across the injector during the whole time that it must stay on. The injector current will be limited by the injector's coil resistance so that no damage will occur. With low impedance injectors this is not the case. When the injector pulse widths are high, driving low impedance injectors in this way will result in excessive current that will damage the injectors and/or ECU.
One solution (the one used by most car manufacturers) is to fit ballast resistors to limit the injector current to a safe level. The only downside of this approach is that it increases the time taken for the injector to open. This is of no concern on most factory engines as the injectors never need to operate near their minimum pulse width for consistent operation.
However, when large injectors are used in after market performance applications, very short pulse widths are required at idle and low load. In this case it is desirable to have an injector that can open as quickly as possible. To do this the G4 Xtreme's injector control can be set to Peak and Hold. This will initially apply the full battery voltage across the injector to open it then the ECU will limit the current to a safe level while still keeping the injector open.
The G4 Xtreme employs low heat technology to digitally control the injectors ensuring minimum current draw and very little heat to be dissipated.
Individual Cylinder Fuel Correction allows the fueling of each individual cylinder to be adjusted independently. This can be used to compensate for slight differences in injector flows, slight differences in fuel pressure at each injector, differences in cylinder temperature due to coolant system design, etc...
