The World's First TFI Box Electronically Fuel-Injected Snowmobiles can boast improved drivability and power with the Dobeck Performance TFI.

The TFI box features simple plug and play installation and quick and easy adjustment. No need for computers and complex maps, just a screwdriver. Uses carburetor tuning logic for easy to understand fuel adjustments.

Dobeck Performance has an electronic jet kit for all the EFI sleds. The real technology behind the TFI box 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 box 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 box 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.

Electronic fuel injection controller (EFI)

Attitude Industries provides a tuning solution for all your electronic fuel injection (EFI) needs. Our EFI controller, the Attitude Box, incorporates technology to function much like a carburetor. It takes the knowledge and tuning experience many of us have had for years and converts it to a fuel injection interface. It makes EFI tuning just like adjusting the pilot jet and mixture screws, needle, or main jet in a carburetor. Our Attitude Box contains multiple different tuning modes determined by colors that are easy to read while riding instead of trying to read a LCD screen. The different colors allow you to quickly figure out what load or RPM range you are currently in. Our fuel injection controller makes it easy to tune for different modifications. The Attitude Box is designed to be used on EFI motors that are stock or have performance enhancement products like air box mods, pipes, heads, big bore kits, nitrous, and even turbos. This EFI controller box does not default computers or trip engine lights thanks to its patented ST technology. The Attitude Box works through a load based system that watches the demand on your motor and makes fuel adjustments to provide a perfectly tuned motor. Most of the time this unit plugs directly into your factory wiring harness for easy installation.
