Fabspeed XperTune ECU Software for Audi RS6 and RS7 (C8)

Confirm the exact C8 control units before arranging this send-in calibration. The detailed supplier notes limit production to June 2020 and identify RS6 explicitly; later units and RS7 coverage need the same exact-vehicle check. 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.

Technical Details

• Manufacturer product reference: FS.AUD.RSXC8.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.
