Fabspeed XperTune ECU Software for Porsche Cayenne GTS and Turbo 4.0 (E3)

Prepare a calibration for an eligible non-hybrid E3 Cayenne 4.0-litre V8. Production date and ECU security matter; the supplier’s stated window reaches a June 2020 ECU-security cutoff. 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.

Before you order

Verify the exact E3 V8 ECU and production date, particularly for a GTS. A control-unit cutoff from a Turbo application must not be transferred automatically.

Technical Details

• Manufacturer product reference: FS.POR.E3T.ECU.
• ECU removal and shipment are required for bench programming.
• Provide the completed vehicle-information form, intended fuel and installed hardware.
• Fabspeed retains the original software; stock restoration and later file revisions may involve a fee.
• Confirm the control-unit version and service arrangements before removing the ECU.
• June 2020 is an ECU-security changeover. Eligibility depends on the exact ECU build and programming access; the calendar month alone is not confirmation.

Use restrictions

The calibration must retain required emissions controls. Fabspeed excludes requests to disable emissions equipment or its monitoring.
