What is a FI controller??
It seems there might be a little misunderstanding about what a FI controller is and what it is used for.
A FI controller has no use on Teryx because a FI controller is for a fuel injection vehicle such as the RZR or the new 700 Rhino. A FI controller is used on a fuel injected vehicle to be able to add or take away fuel just like jetting a carb but done electronically. The stock fuel injection systems have no way of changing the fuel requirements for any engine mods that change the fuel requirements of the engine. The stock system has what is called a Map which goes something like this: When sensor one says this and sensor two says this and sensor three says this then do that. When the data from any of the sensors change there is a Map written to cover it. But the human written maps do NOT cover changes that would occur from modifying an engine. There is also NO oxygen sensor like what is in your car to read air/fuel ratio and change the fueling on the fly. That is what is called a closed loop system and ATV's don't have that.
A FI controller can NOT be used on any aftermarket fuel injection as they are all custom made. All FI controllers are made only for the vehicle stated and are NOT universal. A FI controller is what is called a interceptor or conditioner which intercepts the signal from the sensors in the injection system and conditions the signal before it goes into the ECU and tricks it and some intercept what comes from the ECU and conditions it before it gets to the injector. Any aftermarket injection would have NO use for a FI controller because it would not have the limitations that the stock system has and would not need to be manipulated between the ECU, sensors and injectors.
All this being said, when the Teryx goes fuel injection you can bet Hunterworks will be ahead of the curve because we are already working with the manufacturers on the systems.
We have helped Dynatek, Velocity Devices and MSD in development for several ignitions and fuel controllers.
