Vehicle telematics unit power management

A system and a method using the system for wireless communication using a vehicle telematics unit, including the steps of: prior to a vehicle telematics unit establishing a network connection, assigning a temporary internet protocol (IP) address having a short-term lease duration to a mobile device to permit communication between the telematics unit and the mobile device; and if the network connection is not established prior to the expiration of the short-term lease duration, renewing the temporary IP address, wherein the renewal lease duration is shorter than the earlier lease duration.

Dynamic DHCP for Wi-Fi connectivity in a vehicle

An automotive vehicle having a turbocharged internal combustion engine and a heat initiated exhaust treatment device, such as a catalytic converter, in the exhaust system is provided with a multiple function turbine bypass valve with controls that provide bypass of the exhaust gases directly to the treatment device during warm-up and also provide a boost controlling wastegate function that limits the turbocharger boost pressure during normal operation. Full throttle bypass override to provide turbocharger boost during warm-up as well as other control and operating functions are also disclosed.
