GIAC software for Macan S applications are now available!


GIAC software is now available for the Porsche Macan S (30L V6 twin turbo engine). This software calibration accommodates 91-93 octane fuel, as well as the factory exhaust and intake system. While retaining smooth drivability, the program offers dramatic and consistent power improvements over the OEM software. On 91 octane fuel, gains are as high as 73 wheel HP and 129 ft lbs wheel torque in some areas of the power band. Peak gains are 36 horsepower and 110 ft. /lbs. of torque at four wheels over stock, on 91 octane fuel.

Notable features include the following:
  • properly recalibrated air/fuel ratios,
  • improved throttle response for a drive-by-cable system feel,
  • optimized torque control for smoother, faster shifting.
Dynamometer test results from an MD-500 Mustang dyno are included here. The graph plots power tests (wheel HP and TQ) for a 2015 Porsche Macan S. The red line denotes a completely stock Macan S with OEM software, exhaust, intake and charge cooler, on 91 octane. The blue and green lines denote two different runs for the same Macan S with GIAC 91 octane software, OEM exhaust, OEM intake and OEM charge cooler, also on 91 octane.

The new high security DME 95B906022B Simos SDI10.2 of the Macan S/Macan Turbo prompted GIACís development of an entirely new proprietary flashing protocol for this product line. These ECUs can be flashed in the car through the OBD port for software installation. Contact your local GIAC authorized dealer for additional information and pricing.
