VMAX Volvo VMAX Speed Limiter Removal Emulator
Plug-in emulator that removes the factory VMAX speed ceiling on Volvo FH and FM trucks, allowing operation within the permissible upper performance range without any ECU remapping.
Volvo FH and FM long-haul trucks are renowned for reliability and fuel efficiency, but the factory-programmed VMAX speed ceiling — typically set at 90 km/h — can create real-world scheduling and fleet management challenges on open routes. The Volvo VMAX Speed Limiter Removal Emulator bypasses this restriction at the electronic level without any permanent ECU intervention. Fitted directly onto the existing vehicle connector, it allows the truck to operate within its permissible upper performance range while the engine management system continues to receive consistent, fault-free signals. Fleet operators retain full control over journey planning without being locked to a blanket factory limit.
How Does It Work?
The emulator plugs directly into Volvo's factory connector without cutting wires or soldering. Once connected, it conditions the vehicle speed and wheel revolution signals that feed the ECU's VMAX logic, preventing the factory speed threshold from being enforced. The engine management unit continues to receive coherent data, so no fault codes are generated and no warning lights appear on the dashboard. The device is fully plug-and-play and completely reversible.
