XperTune Performance software upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure. Achieve maximum power from the BMW M340i without sacrificing driveability or reliability by optimizing the engine's performance.

FEATURES:

• For all BWM G20 M340i 2019 - June 2020 Models worldwide
• More power and throttle response
• Increased driveability
• Even more gains can be made with bolt on performance parts

NOTES:

• 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!  
• 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.
• 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.
• Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser.  The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with.  (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground.  If you ship it via Overnight, we will ship it back via Overnight.)
• Special requests and tune file upgrades may be subject to additional fees.
• Why the June 2020 cut-off date? All vehicles that currently use the Bosch MEVD and MG1 family of ECU’s starting mid-June 2020 are completely locked by Bosch. The reason for the update is to provide improved security for autonomous driving and other driving assistance features and keeping hackers away from remotely intervening with the vehicle’s systems. The lock has been introduced in the bootloader of the ECU and is implemented on the processor level, which means that “bench unlocking” with direct access on the ECU is no longer possible.
