Flash Access F56 by Bytetronik

The ECU reflash has been designed to provide smooth additional power while improving drive-ability over OEM mapping. Our tuning philosophy is to safely increase the HP and Torque without pushing it over the edge. Unlike other tuners, we use the dyno as a tuning tool to showcase the “delta” of the increase in performance – we don’t believe in chasing dyno numbers. If you want a tune that can deliver 300HP on stock internals, then our tune is not for you.

Parameters Adjusted:

• Raised Speed limiter (VMAX)
• Fuel Pressure raised
• Target Lambda optimized
• Clutch torque optimized
• Torque monitors optimized
• Race start (launch control) start temperature modified
• Boost target optimized
• Target torque optimized
• Schubblurbben (burble) parameters optimized for more bangs and pop (*This feature is not yet refined on certain 2018 & 2019 models with the latest SW version)

 PLEASE NOTE:  *FOR OFF ROAD USE ONLY* Any modification to your vehicle has the potential to void your car’s factory Warranty. Please check your terms and conditions before purchasing our tune.

Customers who have purchased the OBD2 FlashAccess Module is entitled to One-Customized adjustment. In order to take advantage of this service, we need you to provide a data log (using OBD2 logger such as OBD Fusion) with the following parameters after you have flashed the tune into your ECU:

• Engine Speed
• Absolute Load
• Boost Pressure
• Commanded AFR
• Actual AFR
• Ignition timing

• Pedal position

Our tuner will examine the logs and send a customized tune file back to you.
