ProX Racing Parts has a complete product program of Electronic Fuel Injection Controllers that will make it very simple and easy to adjust your motor's characteristics.

The ProX EFI controller is all plug ?n play and works very simple. It easily plugs into the injectors of the engine and works from the ECU. The controller gives you three basic zones that can be adjusted, actually similar to a carburetor which is very common to most people. One zone sets your ?pilot jet? for idle and cruise, another zone sets your ?needle jet? for acceleration and the third zone sets 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.
