Buick Regal GS and Sport Modes
Certain models of the 2011--2017 Buick Regal vehicles are equipped with additional mode buttons – one is labeled “GS” and the other is labeled “Sport”. Depending on the features of the vehicle, these buttons may change the way the suspension operates, the way the accelerator pedal responds, and/or the way the automatic transmission shifts.
TRIFECTA Exclusive Driver Selectable Vehicle Modes (DSVM)
One of the earliest exclusive TRIFECTA product features is DSVM, formerly known as Select-A-Tune (SAT). Taking root in the days of the first 2.0L turbo Direct-Injected engine GM built (RPO: LNF), SAT was a feature designed to give the driver dynamic control over the vehicle's power output. This feature was a very popular distinguishing feature of the TRIFECTA calibration. Over time it evolved into DSVM by name, and has been implemented in most vehicles that TRIFECTA offers a calibration for.
DSVM and SAT are exclusive because they rely on the specific software that doesn't exist in the OE software. Some vehicles have OE DSVM-like capabilities, such as the 2014-2019 Chevrolet Corvette, but many other vehicles do not.
TRIFECTA has always been interested in whether either (or both) the GS and/or Sport buttons found in the Buick Regal could be tapped into to change the engine's dynamics on the fly. After some amount of research we determined that these buttons can in fact be used to select alternate automatic transmission shift profiles, but selecting alternate performance envelopes and pedal response maps seemed to not be possible with the OE software.
Bringing DSVM to your Buick Regal GS and Sport button
TRIFECTA is proud to announce we have successfully developed the Driver Selectable Vehicle Modes feature for the 2014--2017 Buick Regal, bringing about the ability to change the power and drivability dynamic of their Buick Regal on the fly with the GS and/or Sport button!
Changing modes via the arming state of the Cruise Control system
In developing this feature, we realized our customers who may not have the Sport or GS modes on their vehicle may want to take part in the fun. With that in mind, we've taken things a step further and have integrated the ability to switch modes based on the arming state of the Cruise Control button as well!
Now Regals without the GS/Sport buttons can also enjoy this feature!
When purchasing or updating an existing purchase, customers are now able to select how they want the TRIFECTA calibration to be activated. The available configurations are:
- None ("Always On")
- GS Mode
- Sport Mode
- GS or Sport Mode
- Cruise Control Disarmed
