Before you buy
Adapter not included. You need an MHD-compatible wireless adapter. We stock the MHD Universal Wireless OBDII Wi-Fi Flash Adapter.
Some cars need an unlock. The M2 Competition and European M4 with an OPF always need a bench unlock before OBD flashing, and cars built after 06/2020 need a special unlock. We offer an in-house DME unlock. Message us your VIN if you are unsure.
