The following list details why the G4+ ECUs are so great, but if you talk to someone with a G4 or G4+ 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

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.
