XperTune Performance Software
An ECU reprogram for the Porsche E3 Cayenne S 2.9-litre twin-turbo (2019 to June 2020, non-hybrid models only), adjusting sensor inputs, air/fuel ratios and boost pressure for more horsepower and torque. This is a send-in service rather than a handheld flash: you mail in your ECU, Fabspeed reprograms it within 24-48 hours of receiving it, and ships it back the way it arrived. Fabspeed keeps your original factory settings on file, so the ECU can be reverted to stock later for a small fee. The June 2020 cut-off exists because Bosch locked later ECUs at the processor level, making bench tuning impossible.
Frequently asked
Does the XperTune Performance Software fit my Cayenne?
This listing is specific to the Porsche Cayenne (E3). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Is this a handheld tune or a send-in service?
A send-in service — you mail in your ECU and Fabspeed reprograms and returns it within 24-48 hours of receiving it.
Can I revert to the factory tune later?
Yes, Fabspeed keeps your original settings on file, though reverting to stock later carries a small fee.
Why is this limited to pre-June 2020 cars?
Bosch locked later ECUs at the processor level for security reasons, which makes bench tuning impossible.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
