Diesel engines are the powerhouses driving most big rigs and heavy duty trucks today. They deliver more power and torque than their gasoline powered counterparts. These engines require specific solutions to maximize performance.

Proecutuning has pioneered the first genuine microprocessor based solution for these engines, the VT-2, which delivers results without requiring involved modifications by the user. This plug and play solution can be installed in minutes and leaves no footprint once removed. Benefits are immediate and include improved fuel economy and peak engine performance.

SGW, or Security Gateway, is a new technology used in recent model year vehicles to prevent unauthorized access to a vehicle’s ECU. Some manufacturers using the technology include Chrysler, Dodge, Jeep and many others. The security feature is used mostly in select vehicles manufactured in the year 2018 and newer, and works by isolating traffic from the central vehicle bus network. This is designed to prevent malicious devices from modifying the vehicle ecu and causing damage, as well as eavesdropping and altering critical vehicle systems. While it can be beneficial, the security feature can also cause headaches for many drivers who see it as a way for the dealer to effectively ‘lock out’ the competition from accessing the vehicle ecu without a special dealer tool.

OBD tuning devices which use this port will not be able to access the vehicle ecu and therefore will not be compatible with vehicles using this security feature. Proecutuning has analyzed and tested a workaround which allows our devices to function on these vehicles without requiring involved modifications by the user.
