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.
