VersaTuner 1.7 Released!

[Ugnius@VersaTune]

VersaTune is proud to announce the following changes in VersaTuner 1.7

Extended Load and RPM Axes

Twenty One tables deemed critical to performance tuning and drivability have had their axes extended to 4.0 load and/or 8000 RPM. The tables modified include load targeting, fueling, ignition, valve timing, throttle, and boost control. Proper tuning of large turbo equipped vehicles is finally possible. Drivability is radically improved by removing the on/off behavior of tunes limited to a load of 2.0. All extended tables have “Extended” in the table name.


Removal of injector duty cycle limit

The ECU limits injector duty cycle to 80% to prevent cylinder wall wetting and to control emissions. This limit is seen as the ECU reducing wastegate solenoid duty cycle and closing the throttle at high loads and high rpm despite load targets not being achieved. By allowing the adjustment of this limit, you can now achieve the largest possible injection pulse width - from the close of the exhaust valve through ignition. There is a new table “Max Injector DC” to control this limit.


Ability to Save As in tune editor

We have added a "Save As" button to make it easier to retain a revision history in your tune database. You can change the name, description, and revision number of the tune when you save using the save as button.


Ability to use horizontal and vertical linear interpolation as well as 2D interpolation to fill cell ranges in tables

It is now possible to fill ranges of cells with data using linear and 2D interpolation. Simply populate the ends/corners of the range and click the interpolation button to fill the cells with data. This is very useful for those who create their own table data from scratch rather than modifying OEM values. It is also useful for extending tables beyond load 2.0 in existing tunes.


Log Viewer bug fixes and performance enhancements

The Log Viewer tab now refreshes each time you click on it. Load time for the Log Viewer tab has been significantly reduced for large log databases. Data log junkies rejoice!
