Fabspeed XperTune ECU Software for Porsche Cayenne S 2.9 (E3)

This send-in ECU service recalibrates an eligible E3 Cayenne S 2.9 around its fuel and installed hardware. Check the build date and ECU access before arranging removal, especially around the June 2020 security change. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
