Send your BMW 4 Gran Coupé-series G24-G26 read

WhatsApp 0466 659 997 with the engine, ECU, your tool and what you want. Hand-built files typically return in 10–20 minutes during file-service hours (9am–9pm Mon–Sat AEST).

Vehicle, ECU and read-method data compiled from the published compatibility lists of the flashing tools we work with (files are returned for Autotuner, KESS3, Flex, DFOX, PCMflash, bFlash, BitBox and more). Stock figures are manufacturer-published values as listed by those tools and may vary by market. All tuning files are intended for off-road, motorsport, agricultural or commercial use only; it is the responsibility of the vehicle owner to ensure compliance with local regulations.
