XperTune Performance Software
XperTune ECU software for the McLaren 570S, 570GT, and 540C's 3.8-litre twin-turbo V8 (2015+), taking a stock 532whp/433 lb-ft to 582whp/506 lb-ft on otherwise-stock cars, with maps also available for cars running Fabspeed's sport cats and Supersport X-Pipe exhaust. Fabspeed developed the tune on its in-house dyno rather than in theory; you send in your ECU, it's bench flashed with the upgraded map, and returned ready to refit with your stock settings kept on file. No other modification to the car is required.
Frequently asked
Which cars does the XperTune Performance Software fit?
Fits your McLaren 570S/540C/570GT. Fabspeed lists this piece for: McLaren 570S/570GT/540C (2015+). 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.
How much power does the tune add on a stock car?
Fabspeed's dyno figures show a stock 532whp/433 lb-ft climbing to 582whp/506 lb-ft, a gain of roughly 76whp.
Does it work with other Fabspeed parts?
Yes — maps are also available for cars fitted with Fabspeed's sport cats and Supersport X-Pipe exhaust, with slightly higher peak gains in that configuration.
Is this a physical product?
No, it's a mail-in ECU tune — you send in your ECU for bench flashing and it ships back ready to refit.
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.
