Fabspeed McLaren 570S / 570GT / 540C ExperTune Performance Software


SKU: FS.MCL.570S.ECU Categories: , ,


ExperTune Performance software upgrade improves horsepower, torque, and driving characteristics of the McLaren 570 / 540 by reprogramming various sensor inputs, air/fuel ratios, and boost pressure. Achieve maximum power (~76 whp & 86 ft-lbs) from the 3.8L Twin Turbo V8 without sacrificing driveability or reliability by optimizing the engine’s performance. Greatly enhances the power and dynamic performance and driveability of this wonderful vehicle. Maps are available for completely stock cars, or for cars equipped with Sport Cats, Cat Bypass Pipes, Exhausts, upgraded turbos, and more.

You wouldn’t believe all the power that’s waiting to be unlocked in your 570S / 570GT / 540C. We’ve had ample time with a 570S on our in-house Dynojet to unlock extra power on both stock vehicles and optimize performance with Fabspeed exhaust components.

Once we receive your ECU, our tuner bench flashes it with the upgraded ExperTune map and we return it to you for easy re-installation; no modifications to the vehicle are necessary.

“There is a copious amount of power waiting to be had that McLaren has hidden from you. The 570S responds incredibly well to a tune and rewards you by taking the performance to a whole new level. Our tune brings the turbos to life with a vengeance, the car reaches boost immediately and pulls hard and consistently throughout the power band.The response and power delivery is outstanding, this is a true driving machine. A fully tuned 570S should make 650S owners envious!”


  • This is not a physical/shipped product.  This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.

  • Upgraded at no charge by Fabspeed over the life of the car. Can be flashed back to stock when you would like at any time.

  • While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!

  • You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.

  • Fabspeed Motorsport saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.

Enjoy your increased performance!
