bootmod3 closed beta for the B48 engines has been a great success and we're excited to announce the wait is finally over!

Our development and testing teams have worked tirelessly on BMW B48 engine feature support over the past few months. Once B58 was released back in April focus shifted to B48 testing with a wider closed beta. Initial flash time that includes unlocking the DME is around 3 minutes and switching maps takes just 19 seconds using the standard ENET-OBD cable available on Amazon/eBay or through even some authorized dealers.
