Frieling Racing has just released the ability to flash all F-Series MEVD17 ECUs via the OBDII port. You no longer have to patch or boot mode the ECU first. To flash the ECU, you just need to make the tune of an original file. Most BMW tuners have all original files or you can of course get them by boot moding a ECU. This flashes the full file. The protocol works for end users, slave, and master cables. More details, photos, and video coming soon!
