More and more technology is being added to modern day engines. Many of the new Dirtbikes and ATV have their carburetors changed with Electonic Fuel Injection. For many people Electonic Fuel Injection is a high-tech feature that is not very simple to adjust. ProX is introducing a new line of Electronic Fuel Injection Controllers that will make it very simple and easy to adjust your motor's charactaristics. The ProX EFI Controller is all plug 'n play and very easy to use! The ProX EFI controller easily plugs into the injectors of the engine and works from the ECU. It gives you three basic zones that can be adjusted, actually similar to a carburetor. One zone sets your "pilot jet" for idle and cruise, another zone sets your "needle jet" for acceleration and a third zone set your "main jet" for heavy loading and wide open throttle. A big benefit of the ProX EFI Controller is that for using the product no computer or dyno is needed. With the push of a button you can easily adjust fuel flow and fine tune for modifications such as high compression pistons, cams, intake mods and exhaust. ProX EFI Controller features Simple plug 'n play installation. Easy control by the push of a button. No computer or Dyno needed, easily to adjust between riding sessions. 3 zones to adjust, similar to a carburettor, for simple fine tuning in the preferred area.

The latest generation of MX bikes is brought to market using Electronic Fuel Injection. The majority of the OEM throttle bodies are designed for higher RPM horsepower. However, this is not the best set up for all tracks and riding conditions. ProX now introduces the Velocity Stack! The ProX Velocity Stack is an alloy tube that needs to be installed in the throttle body of the Fuel Injection system. The light weight alloy tube is specially designed and developed to adjust flow so that the engine gets improved bottom power at part openings, plus better and smoother throttle response without re-mapping the ECU. The ProX Velocity Stack will significantly improve drivability and increases torque at the lower rev range, exactly the area where the power is needed! ProX Velocity Stack features Manufactured from high quality alloy with supers mooth finish for high flow. Adjusts flow offering significantly improved drivability and increased torque in the lower rev range. No need to adjust ECU.
