The tuning industry has just taken another significant leap forward. With the latest Magic Motorsport Flex update (version 7.14.0.0), professional tuners can now unlock and remap Bosch MG1CS031 ECUs via OBD, effectively bypassing advanced anti-tuning protections on VAG 2.0L TFSI vehicles.
This development eliminates the need for ECU removal or bench tuning. Tuners can now perform direct OBD connections for safe and efficient programming, streamlining the tuning process considerably.
Expanded Vehicle Compatibility with Magic Motorsport Flex
This update broadens tuning capabilities to include a range of high-performance petrol models, such as:
- Audi S3 2.0L TFSI (310PS)
- Volkswagen Golf R 2.0L TFSI (320PS)
- Cupra Formentor VZ 2.0L TFSI (310PS)
- Skoda Octavia vRS 2.0L TFSI (245PS)
These vehicles, previously secured by sophisticated anti-tuning measures, are now accessible for performance tuning, economy remaps, and custom calibrations directly through the OBD port.
