VMAX Ford F-Max VMAX Speed Limiter Removal Emulator
Removes the factory or fleet-defined VMAX speed cap on Ford Trucks F-MAX long-haul tractors through a plug-in socket connection, with engine power maps left untouched and full reversibility.
The Ford Trucks F-MAX has been the brand's flagship long-haul tractor since its 2018 debut, pairing a 12.7-litre Ecotorq engine with a cab and driveline built for continuous heavy-tonnage work — credentials that earned it the 2019 International Truck of the Year title. What the hardware allows, however, the software often restricts: the VMAX road-speed limit written into the control unit by the factory or by fleet management holds the tractor below a fixed ceiling. On motorway stages, empty return legs and tight delivery windows, that ceiling turns straight into lost hours. The Ford F-Max VMAX Speed Limiter Removal Emulator electronically disables that speed-limit definition, letting the tractor run across the performance range it was engineered for. It installs through the original socket and leaves nothing permanent behind.
How Does It Work?
Fitment is plug-in: the unit connects to the relevant control unit connector on the F-MAX through its original socket, with no wires cut, spliced or soldered. In service it manages the data exchanged between the road-speed signal and the speed-limiting function, so the VMAX threshold the control unit would otherwise apply never engages. Power mapping, torque delivery and every other engine parameter stay exactly as calibrated. Unplug the unit and the tractor reverts to its factory speed limit.
Frequently Asked Questions
Which Ford Trucks F-MAX versions does this emulator work with?
It suits F-MAX tractor units whose control unit runs the VMAX speed-limiting function. Before ordering, check your VIN and control unit type against your service documentation and pass those details to our technical team so compatibility can be confirmed.
Will fitting it alter engine performance or the fuel map?
No. The unit acts on the VMAX speed-limiting function alone; power mapping, torque values and the engine calibration stay as they are. The connection runs through the original socket, so nothing has to be cut or soldered.
If I remove the emulator, does the truck go back to standard?
Yes. The unit sits on the original connector, so unplugging it returns the tractor to its factory-defined speed limit. No permanent trace or damage is left on the vehicle.
What legal points should I be aware of?
Speed limiters are a legal requirement for heavy commercial vehicles in many countries. Using this product is entirely the operator's own responsibility, and any vehicle driven on public roads must comply with the speed, tachograph and roadworthiness rules in force.
