First Ever EFI Controller for Snowmobiles

Dobeck Performance has an electronic jet kit for all the EFI sleds. The real technology behind the TFI is that it functions like a carburetor. It takes the knowledge and experience that many of us have, and converts it to a fuel injection interface. Simply figure at what point you are having your trouble, and based on carburetion logic, determine what circuit you would adjust: pilot jet and mixture screw, needle and slide speed, or main. The corresponding pot in our box will change that point in the fuel delivery curve just like a carb would. These controls make it easy to tune for different modifications. The TFI is to be used on EFI sleds that have performance enhancements that require more fuel to run correctly, such as pipes, heads, even big bore kits. With patented ST technology this box does not default computers, or trip engine lights. The TFI is the only load based system out their that monitors the demand on your motor and its fueling needs, and moves with those needs providing a perfectly tuned fuel curve that moves with your sleds EFI system. This unit plugs directly in your factory wiring harness for easy installs

Key benefits include:

• Allows addition of fuel required with engine modifications without upsetting stock fuel map.
• Integrated dials provide easy adjustment and fine-tuning of fuel delivery curve without external programming devices.
• LED lights indicate fuel delivery settings while tuning
• Won’t interfere with your Sled’s stock sensors and inputs
